A+ Fundamentals Chapter 1 and 2: Becoming an IT Specialist: Troubleshooting and Hardware Essentials

[e-mail]

The digital world seems like magic to many, but behind every functioning computer is a complex system of hardware components and methodical troubleshooting approaches. In this comprehensive episode, we pull back the curtain on what makes IT specialists effective problem-solvers and explore the physical heart of computing systems.

We begin by examining the role of IT specialists as workplace heroes who tackle everything from simple password resets to complex network outages. Through real-world stories and practical examples, we highlight how the best tech professionals combine technical knowledge with crucial soft skills like communication and organization. You'll discover why explaining complex concepts in plain language is just as important as understanding those concepts in the first place.

At the core of effective IT work lies a structured troubleshooting methodology. We break down CompTIA's six-step approach: identifying problems through careful information gathering, establishing theories of probable cause, testing those theories systematically, implementing solutions, verifying full functionality, and documenting everything for future reference. This methodology isn't just exam material—it's a framework that professionals rely on daily to solve real-world tech problems efficiently.

The episode then ventures into hardware territory, exploring the motherboard as the computer's central nervous system. We discuss different form factors, installation procedures, and potential pitfalls like electrostatic discharge. Our journey continues through the evolution of connection standards—from early USB and display technologies to modern Thunderbolt and USB-C implementations—and the expansion cards that enhance computer functionality.

Whether you're studying for CompTIA certification, working in IT, or simply curious about what happens when you call tech support, this episode provides valuable insights into the methodical thinking and technical knowledge that powers our digital world. We wrap up with practice questions that reinforce key concepts and prepare you for both certification exams and real-world scenarios.

Episode Transcript

Speaker 1 (00:01):
Hey, before we get started, I want to do a little
housekeeping.
So you know how I used to dotwo chapters a week.
I would do chapter, let's say,four, part one, and then chapter
four, part two.
Well, I'm going to combine itand it's going to be one chapter
for the week, so we're going todo so.
This gives us an opportunity todo on a Tuesday, let's say,
security Plus, thursday, a+,which is the new series that I

(00:24):
want to start, and then sundaywill be like a fun day and we
can do the history of moderntechnology.
So I'm going to combine theepisodes.
Now it's because I'm on the podmatch network and also my rss
feed, buzzsprout.
In order to get ads it has tobe a certain limit.
It has to be 23 minutes.
So I'm going to make all ofthese shows at least 23 minutes,

(00:47):
maybe longer.
I don't know if you guys likethem longer or shorter.
If you do, just let me know.
But that's the reason why Icombined chapter one and chapter
two, and then on sunday I'llcombine two stories.
So instead of doing one storyon the history of modern
technology, I'll do two, I'll doone back to back.
That way the total is 23minutes and I can meet all the

(01:10):
requirements that you knoweverybody wants me to meet,
reach and hopefully, hopefullywe build this community that I
have myself set up for success.
And you know I have which daysI'm going to do it and how many
I'm going to do a week, and thenI have a lot of time in my

(01:30):
schedule to do all this stuff.
Hopefully you give me theopportunity to come back.
I lost a lot of fans not doingit for 14 months, so hopefully
everybody will come back andthey will continue to listen.

(02:02):
So, without further ado, here'sthe next episode, and welcome to
Technology Tap.
I'm your host, professor J Rod,and today we're diving into the
world of IT specialists,troubleshooting and the very
heart of the computer themotherboard.

(02:24):
Now, whatever you're a studentpreparing for the CompTIA A-plus

(02:49):
certification, someone alreadyworking in IT or just curious
about what goes on inside thesemachines used every day, this
episode's for you.
We'll explore what it means tobe an IT specialist, the skills
you need, the structuredmethodology behind
troubleshooting, and then rollup our sleeves and step into a

(03:10):
hard way world Talking cables,connectors, motherboards and
expansion cards.
By the end, you not onlyunderstand the concepts, but you
also see how they connect tothe real world and to your exam
prep.
So grab a notebook if you'restudying, or just sit back and
enjoy the ride.
Let's get started.
When people ask what does an ITspecialist actually do, I

(03:30):
usually say an IT specialist isa problem solver.
That's in its simplest form.
Every day brings a newchallenge.
One moment you're helping auser recover their password.
The next moment you'rediagnosing a network outage that
keeps an entire office offline.
There is no routine in thisrole.
That's what makes it excitingand also what makes it stressful

(03:51):
.
It specialists are often theunsung heroes of the workplace.
Let me tell you a quick story.
Years ago, I was working on acollege campus and it was
registration week, one of thebusiest time of the year.
Suddenly, the registrar systemswent down.
Students were lined up,panicking because they couldn't
register for their classes.
Staff members were on the edge.

(04:12):
Everyone looked to IT.
Now they could have panicked,but instead they took a deep
breath, remembered theirmethodology and began
systematically diagnosing theproblem.
Within minutes, they had thesystem back online.
Later, one of the staff memberssaid you saved us, referring to
the IT Always being, as Ialways say to my class always be

(04:37):
ready for the unexpected.
Now, what makes a good ITspecialist?
It's not just about technicalknowledge.
Sure, you need to understandthe hardware software.
What makes a good IT specialist?
It's not just about technicalknowledge.
Sure, you need to understandthe hardware software networking
, cloud and security.
But the skills and ability gofar beyond that.
First, as I always tell mystudents, it's communication.

(04:57):
You need to be able to explainwhat you're doing in both
written and oral form.
Sometimes that means tellingyour boss in plain English why
their laptop is running slow.
Sometimes it means documentingin a repair ticket so another
technician can follow up.
Second, organizations.
Think of your workspace likeyour brain If it's cluttered,

(05:20):
finding the right tool or partbecomes a nightmare.
Clean, organized environmentsmake problem-solving faster and
more efficient.
And third, problem-sol partbecomes a nightmare.
A clean, organized environmentmakes problem solving faster and
more efficient.
And third, problem solving as aprocess, not just throwing
darts at the wall, but using astructured, step-by-step
approach.
We'll get into that in the nextsegment.
So to summarize the firstsection, it specialists are

(05:40):
problem solvers, communicators,organizers and lifelong learners
.
It specialists are problemsolvers, communicators,
organizers and lifelong learners.
And if you're preparing for aCompTIA A-plus exam, keep in
mind that the exam doesn't justtest what you know.
It tests how you think.
Critical thinking is veryinvolved in these exams, these
A-plus series that I'm doing inconjunction with the Security

(06:03):
Plus that I'm running parallel.
You will be able to take thesepodcasts and listen to it and
hopefully it will help you withyour exam when you go and take
the exam.
All right, let's move to thedetective work of IT
troubleshooting.
Comptia Online's a six-steptroubleshooting mythology and

(06:24):
it's one you should memorize,not only for this exam but also
for real-world practice.
And also this stuff scaffoldsusing an education term.
So whatever you learn here,it's in Network+, it's in
Security+, it's in Cloud right,so you could always use it.
Step one identify the problem.
That might sound obvious, butit's critical.
Gather as much information aspossible.

(06:45):
Ask the user what error messagedid you see?
When did it start?
Did you change anythingrecently?
Has anyone else experienced theissue?
Let's imagine a user's laptopwon't turn on.
Before jumping into theoriesabout bad motherboards or fried
CPUs, check the simple things.
Is it plugged in?
Is the power strip switched on?
Is the battery charging?

(07:06):
This step alone could savehours, and with CompTIA, they
always want you to try thesimple stuff first.
You try the simple stuff first,then you try the hard stuff.
Step two establish a theory ofpowerable calls.
Maybe it's a bad power adapter,maybe it's a dead battery,
maybe the RAM is loose.
Step three test this theory.

(07:27):
Swap in a different charger,remove and reseat the RAM.
Try booting without peripherals.
See if your theory holds water.
Step four create and implement aplan of action.
If your theory is correct,decide how to fix it.
Replace the battery, order anew power supply, re-image the
system.
Step five verify full systemfunctionality.

(07:48):
Don't just stop when the systemboots.
Make sure the issue is fullyresolved If you replace the hard
drive, test the operatingsystem, the applications, the
network connections.
Step six document everything.
This might be the mostoverlooked step.
Write down what issue was, whatyou tried, what worked, what
didn't.
This documentation helps yourteam in the future and builds a

(08:11):
knowledge base.
Here's a real-world example.
I once got a call about a deadPC.
The user saw it wouldn't turnon.
I arrived, pressed the bowbutton, nothing.
I checked the back, saw thepower cable dangling on the
floor, plugged it in.
Problem solved A $10, a 10cents fix.
Always, always question theobvious right.

(08:31):
And here's an exam tip Expect ascenario question when you have
to choose the next logical step.
If they describe a computer thatwon't boot, don't jump in to
replace the motherboard.
Start with identifying theproblem and always use the super
simple stuff first, becausethat's what CompTIA is looking

(08:53):
for.
So always, always, go for thesuper simple stuff.
You want to check the cables?
You want to check the videocable, the power cable, the
video cable it's the supersimple stuff.
Check that first.

(09:13):
Now that we cover the human sideof IT and the troubleshooting
mindset, let's step into thehardware world.
Inside the PC case, you havecomponents motherboard, cpu RAM
storage and then you haveperipherals.
You have components,motherboard, cpu RAM storage and
then you have peripherals.
Peripherals are the device thatadd functionality Printers,
monitors, external drives,keyboard and mouse.
Let's talk about USB, universalService Bus, and how we connect

(09:36):
peripherals.
Usb 1.0 gave us 1.5 megabitsper second transfer rate
Painfully slow by today'sstandard.
Usb jumped to 480 megabytes.
Usb 3.0 gave us gigabyte speedand USB 4.0 now reaches up to 40
gigabytes per second.

(09:57):
That's faster than some networkconnections.
Here's a real world tie-in.
The European Union now requiressmartphones to use USB-C.
Why?
Because it's universal.
One charge for all devices,reduces waste and makes life
easier.
Display cables are another keytopic.
Vga's analog old school HCMIgives us crisp audio and video

(10:19):
only through a single cable,doesn't give us data.
Displayport is favored bygamers and professionals because
it supports high resolutions,refresh rates and daisy chain
multiple monitors.
And then there's ThunderboltRegular Thunderbolt, thunderbolt
3 and 4, using USB-C connectors, can push data at 40 gigabytes

(10:40):
per second Perfect for externalgraphic cards, high-speed
storage and professional videoequipment.
Apple wants to use aproprietary lightning connector
for iPhones and iPads, but eventhey are shifting towards USB-C.
If you buy a modern iPhone inEurope, you'll likely see a
USB-C instead of lightning inhere too, if you buy in the US.
So whenever you are setting upa desktop, building a gaming PC

(11:07):
or working in enterprise IT,cables and connectors matter.
Get them wrong and you'll bechasing ghosts.
Next, the motherboard.
Now let's head to the star ofthe hardware world the
motherboard.
The motherboard is the central,the star of the hardware world,
the motherboard.
The motherboard is the centralnervous system of the computer.
It connects the cpu, memorystorage, expansion cards and
peripherals.

(11:27):
It's also with the power anddata flow.
Without it, your pc is just acollection of parts.
Major manufacturers includeasus, msi, as rock and Gigabyte.
Motherboards come in differentform factors ATX, the standard
size, about 12 by 9.6 inches.
Microatx, a smaller version at9.6 by 9.6.

(11:51):
And Mini-ITX, even smaller, 6.7by 6.7, often in compact build.
Think of it like vehicles atxis a full-size pickup, micro atx
is compact, usb you suv andmini itx is the sports coupe.
Installing a motherboard is aprocess.

(12:12):
First, review the documentation.
Install the io shield in thecase.
Those are the things where thatplastic shield where you put
like the keyboard and the USBthrough in the back of the
computer that's the IO case.
Insert standoff to keep theboard off the metal case, that's
to put them on the case, themotherboard case.
You put the standoffs first andthen you put the motherboard on

(12:34):
top.
Pre-install the CPU and the RAMif you can it's easier if you
do it outside the case.
Align the board, secure it withscrews and then connect power
cables, storage devices andfront panel headers.
Finally, manage your cable forairflow and aesthetics.
Here's a story I once installeda motherboard but forgot one

(12:54):
standoff.
That caused the board to shortagainst the case.
The system wouldn't boot.
Lesson learned Double checkyour standoffs.
Electric static discharge isanother risk.
Always use grounding strips ormats and keep parts in
anti-static bags until you'reready.
A single static zap can fry adedicated motherboard.
Now, I've never used agrounding strip a wrist strip to

(13:19):
ground myself, but it's in theexam, so you should do it and
you should learn it Right, don'tyou know?
When you get experience, thenyou do whatever you want, but
when you're first starting out,do it the way CompTIA wants it.
Motherboards aren't just aboutbasic.
They also support expansion.
Video cards.
Gpus handle graphic processingwhatever for gaming, 3d modeling

(13:42):
or machine learning.
Capture cards let you stream orrecord video feeds.
Sound cards provide advancedaudio features for professionals
.
Network interface cards expandconnectivity from copper to
fiber to wireless.
Now that we have legacyconnectors, vga and DVI are
still around in some offices,even though HDMI and DisplayPort

(14:03):
have taken over.
Serial cables with the DB9,connectors are dinosaurs, but
you still find them on olderindustrial equipment.
Why does this matter?
Because, as an IT specialist,you might walk into an
environment that mixes brand newhardware with devices that are
20 years old.
Knowing how to recognize andconnect these legacies is still

(14:23):
a valuable skill.
So what did we cover today?
We looked at the role of the ITspecialist, the hero of problem
solving.
We broke down the six-steptroubleshooting mythology.
We explore peripherals, cablesand connectors.
We dug into motherboard itsfunctions, form factors and

(14:45):
installation, and we wrapped upwith the expansion cards and
legacy connectors.
Now, before we stop, I am goingto give you four questions.
Right, I'm going to say thefour questions and we're going
to see how much have you learned, how much have you memorized?
Hopefully you'll get four forfour, but if not, there's always

(15:07):
next episode.
All right, here are your fourquestions.
I'm going to read them twiceand then I'm going to give you
the answer and then anexplanation of why.
All right, question one ITspecialist role.
A user calls the help desk andsays that the monitor is blank,
even though the computer seemsto power on.
As an IT specialist, what'syour first step in

(15:28):
troubleshooting?
A replace the monitorimmediately.
B ask the user if the monitorpower cable is plugged in.
C order a new video card.
D reinstall the operatingsystem.
I'll read it again A user callsthe help desk and says their
monitor is blank, even thoughthe computer seems to power on.
As an IT specialist, what isyour first step in

(15:49):
troubleshooting?
A Replace the monitorimmediately.
B Ask the user if the monitor'spower cable is plugged in.
C Order a new video card.
D Reinstall the operatingsystem.
The correct answer is B Ask theuser if the monitor cable is
plugged in.
Comptia emphasized the firststep is to identify the problem.

(16:09):
That means gathering simple,obvious information first before
jumping into complex solutions.
Always check basics like powercables and connections before
escalating.
It's always the simple, stupidstuff.
Right?
You ever heard that word keepit simple, stupid.

(16:29):
That's kind of like CompTIA'smodel.
But then I got to say stupid.
But you want to always checkthe simplest things first,
because it could be.
You spend hours casing yourtail and it's something really
dumb.
I have done that.
I have done that.
So you don't want to do that,all right.
Question two Troubleshootingmythology.

(16:50):
You tested a theory andconfirmed that a loose RAM
module is preventing a PC frombooting According to CompTIA's
troubleshooting mythology.
What should you do next?
A Document the findings.
B Establish and implement aplan.
I'll read the question againRAM module is preventing PC from
booting According to theCompTIA troubleshooting
methodology.
What should you do next?

(17:21):
A Document the findings.
B Establish and implement aplan of action.
C Escalate the issue to anothertechnician.
Or D Reproduce the error forthe user.
And the answer is drum roll,please.
I'll give you five seconds.
Five, four, three, two, one.
And the answer is B establishand implement a plan of action.

(17:44):
Once your theory is confirmed,the next step is to create a
plan and resolve the issue.
In this case, reseeding the RAMor replacing it is the logical
next action.
Documentation comes last, notimmediately after testing.
All right, hope you got thatright.
Now we are on to question threecables and connectors.

(18:06):
A technician is connecting anew external storage drive to a
workstation that requires 40gigs, 40gb connection over a
USB-C interface.
Which standard should be used?
A USB 2.0, b USB 3.0, c, usb3.2, generation1 or D

(18:28):
Thunderbolt3?
I'll read it again A technicianis connecting a new external
storage drive to a workstationthat requires 40 gigabytes of
connection over USB-C interface.
Which standard should be used AUSB 2.0, b USB 3.0, c, usb 3.2,
generation 1, or D Thunderbolt3?

(18:49):
I'll give you five seconds tothink about it.
Five, four, three, two, one,and the answer is D Thunderbolt
3.
Thunderbolt 3 and 4 both useUSB-C interface and support up
to 40GB transfer speed.
Usb 2, 3, and 3.4 Generation 1all offers slower speeds, maxing

(19:11):
out between 5 and 20GB.
I will tell you one thing aboutcables, and this is in general
with all type of PC.
You can put a USB 2 device on aUSB 1 slot, but it's going to
run at the 1 slot, it's going toout at five.

(19:32):
It's going to run at the five,right, it'll work, but it's
going to run at the lower speed.
It's always going to be likethat in IT when you have two

(19:54):
speeds and they don't matchexactly, it's always going to
run at the lower speed, always,always, all right.
Last question Motherboards andexpansion cards.
A technician is installing anew motherboard in a desktop
case.
Which of the following must beinstalled to prevent shorting
the board against the case AHeatsinks, b Standoff, c IO

(20:18):
Shields, d Thermal Pace?
I'll read the question again Atechnician is installing a new
motherboard in a desktop case.
Which of the following must beinstalled to prevent shorting
the board against the case A hesinks, b Standoff, c IO shield
or D thermal paste?
I'll give you five seconds tothink about it Five, four, three

(20:44):
, two, one.
And the answer is B standoffs.
Standoffs physically separatethe motherboard from the case,
preventing electrical shorts.
Heat sinks and thermal pasteare for cooling the CPU and the
IO shield is for lining ports onthe back of the case.
None of these prevent shorts.
Heat sinks and thermal pasteare for cooling the CPU and the
IO shield is for lining ports onthe back of the case.
None of these prevent shorts.
Now, did you get all four?

(21:05):
Hopefully you did.
Fingers crossed that you did.
But if you didn't, don't worry,we will be back next week to do
another chapter on A+.
All right, so what did we covertoday?
We looked at the role of an ITspecialist, the hero of problem
solving.
We broke down the six-steptroubleshooting mythology.

(21:26):
We explored peripherals, cablesand connectors.
We dug into the motherboard,its functions, form factors and
installation, and we wrapped upwith expansion cards and legacy
connectors.
If you're preparing for theCompTIA A-plus exam, these
concepts you'll see again andagain, not just in test
questions but in your real-worldIT career.

(21:48):
Next week, on Technology Tab,we'll dive into the CompTIA
A-plus series.
We'll dive deep into storagetechnology, from spinning hard
drives to SSD, to NBME andbeyond.
