Hubs do not know which computers are connected to it and do not perform a network operation of the source or target computer. For this, they are defined as stupid devices according to Switches.
If data is sent to a computer on the network, the Hubs send this data to all computers, and the computer that will receive the data checks whether the data was sent to it or not, if it was sent to it, it receives the data. Therefore, hubs do not send anything directly to the computer but help to send. If the target computer accepts, it is thrown into the computer. Hubs are one of the central devices in a star topology. Topology refers to the physical and logical structure of a network.
The connection types of the components that make up the network, the devices to be used, the wiring standards, the selection of the communication protocol, and the applicability of these protocols to the network structure are also within the scope of the topology. They work with plug and play logic.
Another difference is that it is both uncomplicated and cheap. Being cheap is one of the reasons why the hub is preferred. The hub allows computers to communicate on the network. Each computer is connected to the Hub with an Ethernet cable, and information sent from one computer to another passes through the hub. The hub cannot determine the source or destination to which the information it receives is intended to be sent, so it sends the information to all computers connected to it, including the computer that sent the information.
Hub is the central coupling device that connects computers together. There are Active and Passive Hubs. Passive types connect computers but do not process signals.
The Networking Hub sends data to all computers connected to it. If it is the only computer that needs to receive the data, it also keeps them busy as it sends data to other computers connected to it. Therefore, Hubs are weaker in performance than Switches. As many computers as the number of ports can be connected.
Switches, on the other hand, are devices that find a separate path to each data transmission channel with the encryption method. It only sends data to the desired computers. Whichever device is connected to its ports, it prepares a separate path for all of them. It is the same as the hub as the task. but in terms of performance and speed, it is faster than a hub.
The switch looks at which address the incoming data will go to, establishes a connection between the sender and the receiver, and transmits it without the knowledge of other computers and without engaging them.
