Brought to you by the reinvented two thousand twelve Camray.
It's ready. Are you get in touch with technology with
tech Stuff from how stuff works dot Com. Join Josh
and Chuck, the guys who bring you stuff you should know,
as they take a trip around the world to help
you get smarter in a topsy turv economy. Check out
(00:20):
the all new super Stuff Guide to the Economy from

Hello there, everybody, Welcome to tech Stuff. My name is
Chris Bollette. I'm an editor here at how stuff works
dot com and sitting next to me as always as
senior writer Jonathan Strickland. Well that was quick. No, no,
(00:41):
it's Hungarian for hello. Oh okay, I thought you were
saying goodbye. Not yet, all right, I don't know. I'm
kind of in a fog right now. All right, Well,
today we have another one of our famous or soon
to be famous listener mail round up jamborees. I think
(01:02):
this would be number two, So let's get started, shall we. Sure? Right,
So here's the first one. Hi, guys, currently listening to
your April Fools podcast. So I'm so sorry this is
ticket so long for me to get to great stuff.
I think my favorite podcast so far was your two
thousand eight Christmas Picks. I didn't see anything from this
(01:24):
listener in my my stocking, but okay. Thanks. On a
more serious note, I worked for a small coffee roaster
in the Midwest, and I think we almost got involved
in an online scam. Someone emailed a request asking if
we shipped to South Korea and specified a freight company
we should use for a quote. I did an internet
search and found this person's name and email on a
website highlighting online scams. I checked out how stuff works
(01:47):
dot com. Excellent choice, and to scam the article on
how online fraud alerts work, but didn't see anything about
how to report potential scam activity. I went to the
IC three website, but we didn't suffer a financial loss,
so I didn't know if I should still fell out
a complaint. Wow, I can't talk. Do you have any suggestions?
(02:09):
Thanks for all your awesome informative podcasts. I've learned I'm
a techie at heart. Sarah Well, Sarah, Yeah, we can
give you some hints and some some tips. If you
suspect that you've encountered an online fraud. UM. Actually, there
are quite a few different opportunities you could take. It
all depends on sort of the nature of what the
(02:29):
fraud is. But your first assumption to go to i
C three that's actually a pretty good one. I see
three stands for the Internet Crime Complaint Center, and it's
a partnership between the Federal Bureau of Investigation and the
National White Collar Crime Center, And uh, usually that's that's
a pretty good source to go to if you need
(02:50):
to report an online scam. Yeah, they're they're very specialized
toward internet crime, as the name suggests UM, you know,
unlike other eight agencies, so you know, it would be
very helpful. They also have if you are interested in
are not Sarah. They also have a lot of other
scam information on the website. So even if you have
(03:10):
not been specifically targeted, but are interested in scams, you
can find a lot of information about different stuff that's
going on right now, different styles of scams UM and uh,
you know, specifics on what to do with regard to
filling out a complaint. The thing is, if you haven't
actually been scammed, it's kind of I don't know what
(03:31):
they'll actually do if you feel like well, I mean,
you can fill out a complaint and and theoretically they're
going to investigate it, and if they find there's anything
substantive there, then they will proceed. I don't think that
you necessarily have to suffer a loss for them to
be aware of it. I think it's better that you
go ahead and say, you know, this is this is
(03:52):
who I think is trying to defraud me. This is
why I think that here is some supporting evidence. I mean,
you know, you don't to just throw accusations around, right right.
You have to send you have to send some information
about who they are and what you think they were
up to. And you know, if if you actually, um,
(04:12):
you know, go ahead with it and send them information
or send them money, they're gonna want to know exactly
what you did and when it happened and all that information.
Otherwise it's going to be very difficult for them to
investigate it further. But you know, they're gonna want to
know specifics, you know, in in as much detail as
you can give them to them. That's true. And uh,
(04:33):
if um, you know, if that seems like that's not
the right course for you, I've got some other suggestions
you can unn follow UM. If the business that you
suspect is UH is committing fraud or the individual who's
committing fraud is either in the United States or Canada,
you can contact the Better Business Bureau UH. If it's
(04:54):
outside of that, that's outside of their jurisdiction, so that
would not work in that case. UH. Other opportunities you
could You could contact the Federal Trade Commission. That's good
for fraudulent emails or UM or fraudulent businesses UH, the
Attorney General if it's a fraudulent business UM, there's UH.
The e consumer dot gov website is a good place
(05:16):
to go if it's an international company that you suspect
is committing fraud UM. So that's of course one of
the big problems with the Internet. You know, it's a
global entity, so not all the the sites or all
the companies are going to be found in the United States,
which makes it a lot more difficult when you're like, well,
how why can we even do about this if they're
(05:37):
on the other side of the world. Can we even
prosecute anything, you know, any sort of fraud UM. But
you can go to like I said, E Consumer dot
Gov and UH and at least report scams. If nothing
else they can, they can raise awareness UM for phishing emails.
You can use the the usd S SERT, which is
the Computer Emergency Response Team website UH to report that.
(06:01):
You can report fraud to the FBI. You know, this
sounds like it's really kind of scary, spooky stuff, but
really we're talking about people. People's lives can be ruined
by fraud, and it happens all the time, and it's
better to go ahead and report something than to stay
quiet about and just hope that, you know, no one
else gets hurt, Like, you know, we'll eat this loss
(06:21):
and we'll just you know, we don't want to suffer
the embarrassment of admitting that this happened, or you know,
we don't want to go through the paperwork. That's really
kind of irresponsible. It's much better to go ahead and
step forward and say, hey, these guys over here are
just are taking people for whatever they can and we
need to stop it. UM and UH. And then there's
a www. Dot fraud dot org, which is the National
(06:43):
Consumer League's fraud center that's not a government site, that
is a nonprofit consumer sites. Actually one of the oldest
ones that exist, and uh, they have a they have
a lot of information about fraud, how to spot it,
how to avoid it, how to report it. And you
can report something to that center and they will they
(07:05):
will take it from there. They'll actually start going through
and say, Okay, these are the authorities we should contact.
Here's the information that we have to pass along to them. Um.
So that's a good resource too. Now I know that
we tend to concentrate on the United States, so I
actually looked into a couple of other opportunities as well.
(07:25):
So for my friends up in Canada who are still
mad that I said that they don't use one, I
just mean that you guys don't have emergencies because you're
so level headed. Um. No, seriously, I know now that
you use. At the time, I wasn't sure and I
couldn't get to my computer, so I apologized profusely. Please
stop throwing bacon at me. But in Canada, you can
(07:48):
again contact the Better Business Bureau or Industry Canada Consumer Connection,
which is and I followed by three CS. Do you
think that causes any confusion? There are lots of three
I found that out, um. And then over in the
UK you can contact the Metropolitan Police or the Office
(08:10):
of Fair Trading, or you can go to a website
www dot rip Off, tip Off dot net to report scams.
And there are many other organizations you can contact. And
of course those are just two other countries. Every country
has has different departments that you can contact in the
case of scams. Um and a good resource to go
(08:31):
to for really any any person in any country is
www dot Consumer Fraud Reporting dot org. They actually maintain
a list of various countries and the department that you
would need to contact if you were to encounter fraud online.
And it seems, Sarah that your your instincts were good
because you knew something fishy was was going on. And um,
(08:54):
I know it's been said many, many, many times and
it's sort of cliche now, but yeah, if something seems
too good to be true, it probably is. So you know,
trust your gut feeling when somebody offers you something that
seems a little out of the ordinary. Uh. You know,
as far as a business proposition, I would imagine that
you know, businesses have to you know, you're looking for
(09:16):
every opportunity to to do more business. Um, you know
versus Hello, beneficiary, I want to uh, trade, you know,
trade your information. Hello, Mr so and so, I am
I am a lawyer for Mr so and so who
was sick in Nigeria. Yeah, yeah, so, I'm sure for
for business, it's got to be a little tougher because you're,
(09:37):
you know, you're looking for an opportunity to actually, you know,
conclude a deal. But uh, you know, you've got to
trust those instincts because if something smells a little fishy,
you need to to look into it, even if you
don't uh, if you don't bite, and it's uh, you know,
people know. And I encountered a lot of this back
back when I worked at a different job. I was
manned the phones every now and then and occasional and
(10:00):
we would get the phone version of this kind of
scam where someone asks you a couple of questions and
just by saying yes, they go ahead and put down
the the you know, the the client agreed to this service,
and then they start charging you for it, and people
are like, why are we getting charged for this paper
from this vendor? We don't even use this vendor. And
it was all based off of this one phone call
(10:21):
where they trick someone into saying yes, and that's that
is the basis of their agreement. Um, it's pretty scummy stuff,
and yeah, you find it. You find it in all
walks of life. It's just the Internet makes it, yeah,
because you can then scam people all the way across
the world. You aren't limited to the people in your
area code. Thank you Internet. It sure is moving on.
(10:47):
So our next question comes from Eric, and Eric wanted
to know the difference between the terms hardware, software, and firmware.
We talked a little bit about firmware in a previous
episode and he was just kind of curious, says to,
you know, what exactly is firmware? So really you have
to talk about all three to kind of explain. So first,
let's tackle hardware. That's pretty easy. Yeah, that's why I
(11:09):
wouldn't tackle it first. Those are those are well, in
the case of electronics and technology, the machines themselves, the
physical devices your monitor, your computer, your iPod, your adapter, cars,
tax machine, cables, anything like that, if you can touch it, Um,
you know technology, it's it's hardware, right, So that's pretty easy.
(11:33):
And then software are programs and applications that run on hardware. Um,
so this is like all the different programs things that
you rely on day to day operating systems can be
you know, that's software as well. Um, so this is
all the little happy programs that make your technology useful.
So it could be anything from like software on computer,
software on a mobile device. Uh, you know, even on
(11:55):
some watches things like that. I mean pretty much any
electronic device that can do us to phisticated sort of task,
it's using some sort of software. So the the hardware
is the machine that without the software, it couldn't do anything.
So that you know, the software is the program that
runs on the machine and gets it to do things.
What is firmware? Yes, it's kind of um, yeah, firmware
(12:18):
is this this gray area that you know, there's no
definitive point where you can say this is firmware and
this is software. Right, Well, it's sort of a combination.
It's it's literally a combination of the two, but only
for a very specific part of the hardware and a
very specific part of the software. Yeah, and it tends
to be these tend to be very tiny applications that
(12:38):
are hard coded into some part of the hardware on
your device, sort of like a driver. Really, it could
be very much like a driver or you know, a
microprocessor has machine code coded onto it, otherwise it can't work. Um.
You know, when you're running a program, ultimately it's getting
translated into machine code and then translate back into whatever,
(13:00):
you know, whatever the program is doing. But um, that's
you know, that's the very core of how a computer works.
So the firmware is the stuff that is hard coded
part of the device. Uh. You know, you can't remove it,
you can't write over it. It's it's what it's what
allows software to communicate with the hardware so that you
get results. Yeah, it's um, it's actually stored in ROM,
(13:23):
which is read only memory and UM, so it can
only be found on him on a ROM that's inside
of your machine. So it's uh, you know, it's not
something that's on your hard drive or anything like that.
It would actually be in the chips themselves. Right. You
can think of things like, um, I I would you
call say, a cartridge game, would you call that firmware
(13:45):
because it's hardcoded onto the cartridge? Well, um, that's a
really good question you answer for you mean, like, yes,
don't say the game. I'm not But those were those cartridges,
those older cartridges up until you know I guess Nintendo
sixty four era type stuff. Um, you know those those
(14:06):
you can't write to those cartridges. I mean you can,
but you have to have a burner to do it,
and it's a pain in the neck. You're you're putting
it inside your game machine. You're not writing to them.
Those are those are rams? Um, and uh so technically yeah,
they're kind of fit in that area. I think though
that people would tell you if we went to talk
to a programming expert, um, they would say that something
(14:29):
inside the on the on the chips itself that tell
the chips how to handle that would actually be firmware
where the software is on the actual fair enough. So
what what about a RAM chip that you would find
in an old fashioned arcade game? See now that I'm
thinking would probably be technically firmware. Somebody's gonna write to us.
(14:53):
Just make make sure you put attention Pallette. So, yes,
if you would like to clarify our position, you know,
were not this The thing is that really firmware is
kind of it's a it's a little bit of a
fuzzy term because there are some points where you're where
you might say, well, is a driver really firmware or
is that software because drivers are what allow you know,
(15:14):
devices to interact with programs. So this goes back to
our our our semi definition that we're making up as
we go along, which is, um, if you download a
driver for your printer, you're storing it on your hard drive,
software on your hard drive that your computer hardware uses
to access the printer. But say you have to update
(15:37):
the firmware in your wireless router, and that way, you know,
you're having to download information that gets stored written back
onto the router to make it, you know, do what
it needs to do to interact with your computer and stuff. Eric,
I'd like to thank you for breaking text stuff. Well,
(15:58):
very much impressed, you know, I I will admit, uh,
you know, hey, I didn't really know everything about firmware
and I still don't, but I know a lot more
now from doing research changes questions. So if you have
a clarification and want to help out, if you're a
programmer expert, you know, please drop us a line. And
it may very well be that certain. You know, within
different industries you have different definitions of what this really means.
(16:21):
I mean, that's true. I was using a general Yeah,
because because someone might think of firmware one way for
say a laptop, and a different different way of thinking
about when you're talking about say a mobile phone or
or an Xbox three sixty. I mean, you know, we
have game consoles now they get firmware updates to correct
for problems. So you know, this is no longer just
(16:45):
the realm of the computer. Um, it's really lots of
different devices, but it's it's essentially chip instructions versus the
software that actually runs, you know, when you open a
program on your machine. So thanks a lot, Eric, I
hope that muddy up the waters a little bit. Yeah, yea, Well,
we have one more ready for the last one. Right,
(17:08):
Hey guys, I'm a new listener, but have only six
more of your podcast to listen to keep quick Yeah,
caught up really quickly. I can't get enough information. So
thanks on your Rechargeable Batteries podcast, I was hoping you'd
address one aspect of charging. The scenario is I've been
playing on my eye Touch all okay, I guess that's
the iPod Touch all night, and I realized it's getting
(17:31):
late and I need to charge it so I can
take it with me tomorrow and have enough battery to
last the day. But if I plug it in now
and leave it in all night, I'm worried I'll overcharge
the battery. So my question is can you overcharge batteries?
Thanks for your help, Aaron. All right, Aaron, Well, um,
so we're talking about rechargeable batteries. Whether you know, we
(17:51):
we talked a lot about what was the best way
to charge them. You know, how charge is lost over
the duration of the lifetime of the battery, that kind
of thing. You remember this podcast? I do remember that podcast. So, um,
so yeah overcharging. Uh, first of all, you asked, can
you overcharge batteries? The answer to that is sometimes, Well,
the answer to that is yes, but it's sort of
(18:14):
it's very difficult to do it because depending on the
kind of battery you have, and depending on the machine
you're using to charge it. Um, It's it's unlikely that
you're gonna do that. Um because most chargers have some
technology built in to keep you from overcharging your battery. Yeah,
it'll detect how much of voltage your battery is storing,
(18:37):
and if it's over a certain amount, it'll stop sending
a charge to that battery. Essentially, laptop batteries are pretty
smart in that regard because they can they generally have
some technology built in to say, oh, well this is
this is enough, you don't need to charge anymore. So
let's just say, for sake of argument, that your charger,
the voltmeter no longer accurately measures the voltage in your battery.
(19:03):
So let's say that you've kept the the device, computer,
whatever plugged in for like a day. Uh, what's the
worst thing that can happen? Okay, So the best thing
that can happen is that your battery overheats a bit
and it damages the battery and your battery life suffers
as a result. And that's probably going to be the
most common thing that happens. That's like, by and large,
the best best case scenario. Worst case scenario, the battery
(19:27):
bursts into flames and burns down half of Detroit, um,
even if you lived in St. Louis. No, that's that's
that's a bit of an exaggeration. Uh No, No, it
really could. Though. It could burst into flames. I mean
that is a possibility. It's not likely to happen, um,
but it is. It is a potential danger that every
(19:48):
lithium ion battery really has. It's that if you overcharge it,
it might it might burn up. Actually, you make a
good point, because I forgot to mention that the research
that I did was speci typically for lithium ion batteries,
which is the most common battery found in laptops and
portable electronics, you know, chargeable stuff. Now, there are other
kinds of chargeable batteries, so your mileage may vary. Battery
(20:13):
is actually a little more dangerous, I think. But the
nickel acadmium, yeah, well they're not used as much as
they used to be either. Um and and lithium ion
also has a you know, you've seen those laptops that
have burst into flames. Um that's called thermal runaway. And
I had one. They burst into flames and just cut Yeah,
they got extremely hot, and that's uh, that can actually
(20:35):
happen by itself when you're not charging, but that requires
a serious breakdown in the battery itself too. You know,
we're talking about chemical reactions that kind of cause the
stuff to happen. So that's unrelated to the charging. Well
I guess we're charging. Yeah, So anyway, Yes, it is possible.
It's not easy to do, so you probably don't need
to worry about it. But in general, don't leave anything
plugged in for twenty four hours. Yeah, you'll if you
(20:58):
read the instructions that with your portable electronic device, computer, etcetera. Um,
you'll you'll get instructions and a lot of them will
tell you, yeah, go ahead and plug it in and
charge it overnight for the first time or you know.
I think if you come home, your batteries run down,
you plug it into the charger, and then the next
morning before you leave, you unplug it. I don't think
that's gonna cause a big problem. It's when you leave
(21:20):
it plugged in for days and days and days and
days and days, especially when it's something that's less intelligent. Um,
like if you've just had batteries sitting at home in
a charger and they were just well, you know, I'll
leave them in there so they're always ready. Probably not
leaving your laptop plugged in all the time is not
probably gonna cause a big problem because it's a little
(21:41):
smarter than that. Yeah, so in general you're probably okay, Um,
don't leave your your device is plugged in for twenty
four hours or more at a time. Just to avoid that,
because that's that that can cause damage. Even if it
doesn't damage the battery directly. Uh, it might, you know,
the charger, It might wear the charger down fast, I
mean or the battery. Yeah, or the battery. That's true.
(22:03):
The battery life can suffer if it overheats for an
extended period of time. That can that can cause the
chemical reactions to be less efficient, and then it doesn't
hold a chart as much of a charge as it
used to. And that's a simple way to tell. I
feel it. It's the battery. Yeah, you know, if it's
a little warm, you know, oh that's kind of warm. Wow,
that's that's that's pretty dark. If you're using a device
(22:26):
like I don't know, the HTC G one Google Android Farm. Uh,
if you're using like that with all of its functions going,
it can warm up all on its own. So that's
not necessarily a sign of the battery overheating. Um, that's
a sign of the processor getting really hot. I found
that out the hard way. So now I don't use
nearly as many functions at a time. Well, I use uh,
(22:49):
you know, my my laptop at home is a as
an Apple aluminum case laptop, you know, and then there's
that you know, working in the summer wearing shorts, thing
going well, that is awfully warm, So that's you know,
they're use your head. But yeah, I mean, if you
feel your battery and it's warmer than it should be
while it's charging, and you know, for example, you're not
(23:10):
actually doing anything with the battery, you know, it's just
plugged in, that's that's a bad time. So that about
wraps it up for this this podcast. I think you
don't have anything else in So if any of you
have any questions or concerns, or you want to try
and get something off your chest, like the image of
Chris and Shorts working on a laptop. If you want

substantive there, then they will proceed. I don't think that
you necessarily have to suffer a loss for them to
be aware of it. I think it's better that you
go ahead and say, you know, this is this is
(03:52):
who I think is trying to defraud me. This is
why I think that here is some supporting evidence. I mean,
you know, you don't to just throw accusations around, right right.
You have to send you have to send some information
about who they are and what you think they were
up to. And you know, if if you actually, um,
(04:12):
you know, go ahead with it and send them information
or send them money, they're gonna want to know exactly
what you did and when it happened and all that information.
Otherwise it's going to be very difficult for them to
investigate it further. But you know, they're gonna want to
know specifics, you know, in in as much detail as
you can give them to them. That's true. And uh,
(04:33):
if um, you know, if that seems like that's not
the right course for you, I've got some other suggestions
you can unn follow UM. If the business that you
suspect is UH is committing fraud or the individual who's
committing fraud is either in the United States or Canada,
you can contact the Better Business Bureau UH. If it's
(04:54):
outside of that, that's outside of their jurisdiction, so that
would not work in that case. UH. Other opportunities you
could You could contact the Federal Trade Commission. That's good
for fraudulent emails or UM or fraudulent businesses UH, the
Attorney General if it's a fraudulent business UM, there's UH.
The e consumer dot gov website is a good place
(05:16):
to go if it's an international company that you suspect
is committing fraud UM. So that's of course one of
the big problems with the Internet. You know, it's a
global entity, so not all the the sites or all
the companies are going to be found in the United States,
which makes it a lot more difficult when you're like, well,
how why can we even do about this if they're
(05:37):
on the other side of the world. Can we even
prosecute anything, you know, any sort of fraud UM. But
you can go to like I said, E Consumer dot
Gov and UH and at least report scams. If nothing
else they can, they can raise awareness UM for phishing emails.
You can use the the usd S SERT, which is
the Computer Emergency Response Team website UH to report that.
(06:01):
You can report fraud to the FBI. You know, this
sounds like it's really kind of scary, spooky stuff, but
really we're talking about people. People's lives can be ruined
by fraud, and it happens all the time, and it's
better to go ahead and report something than to stay
quiet about and just hope that, you know, no one
else gets hurt, Like, you know, we'll eat this loss
(06:21):
and we'll just you know, we don't want to suffer
the embarrassment of admitting that this happened, or you know,
we don't want to go through the paperwork. That's really
kind of irresponsible. It's much better to go ahead and
step forward and say, hey, these guys over here are
just are taking people for whatever they can and we
need to stop it. UM and UH. And then there's
a www. Dot fraud dot org, which is the National
(06:43):
Consumer League's fraud center that's not a government site, that
is a nonprofit consumer sites. Actually one of the oldest
ones that exist, and uh, they have a they have
a lot of information about fraud, how to spot it,
how to avoid it, how to report it. And you
can report something to that center and they will they
(07:05):
will take it from there. They'll actually start going through
and say, Okay, these are the authorities we should contact.
Here's the information that we have to pass along to them. Um.
So that's a good resource too. Now I know that
we tend to concentrate on the United States, so I
actually looked into a couple of other opportunities as well.
(07:25):
So for my friends up in Canada who are still
mad that I said that they don't use one, I
just mean that you guys don't have emergencies because you're
so level headed. Um. No, seriously, I know now that
you use. At the time, I wasn't sure and I
couldn't get to my computer, so I apologized profusely. Please
stop throwing bacon at me. But in Canada, you can
(07:48):
again contact the Better Business Bureau or Industry Canada Consumer Connection,
which is and I followed by three CS. Do you
think that causes any confusion? There are lots of three
I found that out, um. And then over in the
UK you can contact the Metropolitan Police or the Office
(08:10):
of Fair Trading, or you can go to a website
www dot rip Off, tip Off dot net to report scams.
And there are many other organizations you can contact. And
of course those are just two other countries. Every country
has has different departments that you can contact in the
case of scams. Um and a good resource to go
(08:31):
to for really any any person in any country is
www dot Consumer Fraud Reporting dot org. They actually maintain
a list of various countries and the department that you
would need to contact if you were to encounter fraud online.
And it seems, Sarah that your your instincts were good
because you knew something fishy was was going on. And um,
(08:54):
I know it's been said many, many, many times and
it's sort of cliche now, but yeah, if something seems
too good to be true, it probably is. So you know,
trust your gut feeling when somebody offers you something that
seems a little out of the ordinary. Uh. You know,
as far as a business proposition, I would imagine that
you know, businesses have to you know, you're looking for
(09:16):
every opportunity to to do more business. Um, you know
versus Hello, beneficiary, I want to uh, trade, you know,
trade your information. Hello, Mr so and so, I am
I am a lawyer for Mr so and so who
was sick in Nigeria. Yeah, yeah, so, I'm sure for
for business, it's got to be a little tougher because you're,
(09:37):
you know, you're looking for an opportunity to actually, you know,
conclude a deal. But uh, you know, you've got to
trust those instincts because if something smells a little fishy,
you need to to look into it, even if you
don't uh, if you don't bite, and it's uh, you know,
people know. And I encountered a lot of this back
back when I worked at a different job. I was
manned the phones every now and then and occasional and
(10:00):
we would get the phone version of this kind of
scam where someone asks you a couple of questions and
just by saying yes, they go ahead and put down
the the you know, the the client agreed to this service,
and then they start charging you for it, and people
are like, why are we getting charged for this paper
from this vendor? We don't even use this vendor. And
it was all based off of this one phone call
(10:21):
where they trick someone into saying yes, and that's that
is the basis of their agreement. Um, it's pretty scummy stuff,
and yeah, you find it. You find it in all
walks of life. It's just the Internet makes it, yeah,
because you can then scam people all the way across
the world. You aren't limited to the people in your
area code. Thank you Internet. It sure is moving on.
(10:47):
So our next question comes from Eric, and Eric wanted
to know the difference between the terms hardware, software, and firmware.
We talked a little bit about firmware in a previous
episode and he was just kind of curious, says to,
you know, what exactly is firmware? So really you have
to talk about all three to kind of explain. So first,
let's tackle hardware. That's pretty easy. Yeah, that's why I
(11:09):
wouldn't tackle it first. Those are those are well, in
the case of electronics and technology, the machines themselves, the
physical devices your monitor, your computer, your iPod, your adapter, cars,
tax machine, cables, anything like that, if you can touch it, Um,
you know technology, it's it's hardware, right, So that's pretty easy.
(11:33):
And then software are programs and applications that run on hardware. Um,
so this is like all the different programs things that
you rely on day to day operating systems can be
you know, that's software as well. Um, so this is
all the little happy programs that make your technology useful.
So it could be anything from like software on computer,
software on a mobile device. Uh, you know, even on
(11:55):
some watches things like that. I mean pretty much any
electronic device that can do us to phisticated sort of task,
it's using some sort of software. So the the hardware
is the machine that without the software, it couldn't do anything.
So that you know, the software is the program that
runs on the machine and gets it to do things.
What is firmware? Yes, it's kind of um, yeah, firmware
(12:18):
is this this gray area that you know, there's no
definitive point where you can say this is firmware and
this is software. Right, Well, it's sort of a combination.
It's it's literally a combination of the two, but only
for a very specific part of the hardware and a
very specific part of the software. Yeah, and it tends
to be these tend to be very tiny applications that
(12:38):
are hard coded into some part of the hardware on
your device, sort of like a driver. Really, it could
be very much like a driver or you know, a
microprocessor has machine code coded onto it, otherwise it can't work. Um.
You know, when you're running a program, ultimately it's getting
translated into machine code and then translate back into whatever,
(13:00):
you know, whatever the program is doing. But um, that's
you know, that's the very core of how a computer works.
So the firmware is the stuff that is hard coded
part of the device. Uh. You know, you can't remove it,
you can't write over it. It's it's what it's what
allows software to communicate with the hardware so that you
get results. Yeah, it's um, it's actually stored in ROM,
(13:23):
which is read only memory and UM, so it can
only be found on him on a ROM that's inside
of your machine. So it's uh, you know, it's not
something that's on your hard drive or anything like that.
It would actually be in the chips themselves. Right. You
can think of things like, um, I I would you
call say, a cartridge game, would you call that firmware
(13:45):
because it's hardcoded onto the cartridge? Well, um, that's a
really good question you answer for you mean, like, yes,
don't say the game. I'm not But those were those cartridges,
those older cartridges up until you know I guess Nintendo
sixty four era type stuff. Um, you know those those
(14:06):
you can't write to those cartridges. I mean you can,
but you have to have a burner to do it,
and it's a pain in the neck. You're you're putting
it inside your game machine. You're not writing to them.
Those are those are rams? Um, and uh so technically yeah,
they're kind of fit in that area. I think though
that people would tell you if we went to talk
to a programming expert, um, they would say that something
(14:29):
inside the on the on the chips itself that tell
the chips how to handle that would actually be firmware
where the software is on the actual fair enough. So
what what about a RAM chip that you would find
in an old fashioned arcade game? See now that I'm
thinking would probably be technically firmware. Somebody's gonna write to us.
(14:53):
Just make make sure you put attention Pallette. So, yes,
if you would like to clarify our position, you know,
were not this The thing is that really firmware is
kind of it's a it's a little bit of a
fuzzy term because there are some points where you're where
you might say, well, is a driver really firmware or
is that software because drivers are what allow you know,
(15:14):
devices to interact with programs. So this goes back to
our our our semi definition that we're making up as
we go along, which is, um, if you download a
driver for your printer, you're storing it on your hard drive,
software on your hard drive that your computer hardware uses
to access the printer. But say you have to update
(15:37):
the firmware in your wireless router, and that way, you know,
you're having to download information that gets stored written back
onto the router to make it, you know, do what
it needs to do to interact with your computer and stuff. Eric,
I'd like to thank you for breaking text stuff. Well,
(15:58):
very much impressed, you know, I I will admit, uh,
you know, hey, I didn't really know everything about firmware
and I still don't, but I know a lot more
now from doing research changes questions. So if you have
a clarification and want to help out, if you're a
programmer expert, you know, please drop us a line. And
it may very well be that certain. You know, within
different industries you have different definitions of what this really means.
(16:21):
I mean, that's true. I was using a general Yeah,
because because someone might think of firmware one way for
say a laptop, and a different different way of thinking
about when you're talking about say a mobile phone or
or an Xbox three sixty. I mean, you know, we
have game consoles now they get firmware updates to correct
for problems. So you know, this is no longer just
(16:45):
the realm of the computer. Um, it's really lots of
different devices, but it's it's essentially chip instructions versus the
software that actually runs, you know, when you open a
program on your machine. So thanks a lot, Eric, I
hope that muddy up the waters a little bit. Yeah, yea, Well,
we have one more ready for the last one. Right,
(17:08):
Hey guys, I'm a new listener, but have only six
more of your podcast to listen to keep quick Yeah,
caught up really quickly. I can't get enough information. So
thanks on your Rechargeable Batteries podcast, I was hoping you'd
address one aspect of charging. The scenario is I've been
playing on my eye Touch all okay, I guess that's
the iPod Touch all night, and I realized it's getting
(17:31):
late and I need to charge it so I can
take it with me tomorrow and have enough battery to
last the day. But if I plug it in now
and leave it in all night, I'm worried I'll overcharge
the battery. So my question is can you overcharge batteries?
Thanks for your help, Aaron. All right, Aaron, Well, um,
so we're talking about rechargeable batteries. Whether you know, we
(17:51):
we talked a lot about what was the best way
to charge them. You know, how charge is lost over
the duration of the lifetime of the battery, that kind
of thing. You remember this podcast? I do remember that podcast. So, um,
so yeah overcharging. Uh, first of all, you asked, can
you overcharge batteries? The answer to that is sometimes, Well,
the answer to that is yes, but it's sort of
(18:14):
it's very difficult to do it because depending on the
kind of battery you have, and depending on the machine
you're using to charge it. Um, It's it's unlikely that
you're gonna do that. Um because most chargers have some
technology built in to keep you from overcharging your battery. Yeah,
it'll detect how much of voltage your battery is storing,
(18:37):
and if it's over a certain amount, it'll stop sending
a charge to that battery. Essentially, laptop batteries are pretty
smart in that regard because they can they generally have
some technology built in to say, oh, well this is
this is enough, you don't need to charge anymore. So
let's just say, for sake of argument, that your charger,
the voltmeter no longer accurately measures the voltage in your battery.
(19:03):
So let's say that you've kept the the device, computer,
whatever plugged in for like a day. Uh, what's the
worst thing that can happen? Okay, So the best thing
that can happen is that your battery overheats a bit
and it damages the battery and your battery life suffers
as a result. And that's probably going to be the
most common thing that happens. That's like, by and large,
the best best case scenario. Worst case scenario, the battery
(19:27):
bursts into flames and burns down half of Detroit, um,
even if you lived in St. Louis. No, that's that's
that's a bit of an exaggeration. Uh No, No, it
really could. Though. It could burst into flames. I mean
that is a possibility. It's not likely to happen, um,
but it is. It is a potential danger that every
(19:48):
lithium ion battery really has. It's that if you overcharge it,
it might it might burn up. Actually, you make a
good point, because I forgot to mention that the research
that I did was speci typically for lithium ion batteries,
which is the most common battery found in laptops and
portable electronics, you know, chargeable stuff. Now, there are other
kinds of chargeable batteries, so your mileage may vary. Battery
(20:13):
is actually a little more dangerous, I think. But the
nickel acadmium, yeah, well they're not used as much as
they used to be either. Um and and lithium ion
also has a you know, you've seen those laptops that
have burst into flames. Um that's called thermal runaway. And
I had one. They burst into flames and just cut Yeah,
they got extremely hot, and that's uh, that can actually
(20:35):
happen by itself when you're not charging, but that requires
a serious breakdown in the battery itself too. You know,
we're talking about chemical reactions that kind of cause the
stuff to happen. So that's unrelated to the charging. Well
I guess we're charging. Yeah, So anyway, Yes, it is possible.
It's not easy to do, so you probably don't need
to worry about it. But in general, don't leave anything
plugged in for twenty four hours. Yeah, you'll if you
(20:58):
read the instructions that with your portable electronic device, computer, etcetera. Um,
you'll you'll get instructions and a lot of them will
tell you, yeah, go ahead and plug it in and
charge it overnight for the first time or you know.
I think if you come home, your batteries run down,
you plug it into the charger, and then the next
morning before you leave, you unplug it. I don't think
that's gonna cause a big problem. It's when you leave
(21:20):
it plugged in for days and days and days and
days and days, especially when it's something that's less intelligent. Um,
like if you've just had batteries sitting at home in
a charger and they were just well, you know, I'll
leave them in there so they're always ready. Probably not
leaving your laptop plugged in all the time is not
probably gonna cause a big problem because it's a little
(21:41):
smarter than that. Yeah, so in general you're probably okay, Um,
don't leave your your device is plugged in for twenty
four hours or more at a time. Just to avoid that,
because that's that that can cause damage. Even if it
doesn't damage the battery directly. Uh, it might, you know,
the charger, It might wear the charger down fast, I
mean or the battery. Yeah, or the battery. That's true.
(22:03):
The battery life can suffer if it overheats for an
extended period of time. That can that can cause the
chemical reactions to be less efficient, and then it doesn't
hold a chart as much of a charge as it
used to. And that's a simple way to tell. I
feel it. It's the battery. Yeah, you know, if it's
a little warm, you know, oh that's kind of warm. Wow,
that's that's that's pretty dark. If you're using a device
(22:26):
like I don't know, the HTC G one Google Android Farm. Uh,
if you're using like that with all of its functions going,
it can warm up all on its own. So that's
not necessarily a sign of the battery overheating. Um, that's
a sign of the processor getting really hot. I found
that out the hard way. So now I don't use
nearly as many functions at a time. Well, I use uh,
(22:49):
you know, my my laptop at home is a as
an Apple aluminum case laptop, you know, and then there's
that you know, working in the summer wearing shorts, thing
going well, that is awfully warm, So that's you know,
they're use your head. But yeah, I mean, if you
feel your battery and it's warmer than it should be
while it's charging, and you know, for example, you're not
(23:10):
actually doing anything with the battery, you know, it's just
plugged in, that's that's a bad time. So that about
wraps it up for this this podcast. I think you
don't have anything else in So if any of you
have any questions or concerns, or you want to try
and get something off your chest, like the image of
Chris and Shorts working on a laptop. If you want
