difference between a

hub and a switch A network device that is used to connect the components of a network to each other is called a switch. Switches in the data link layer (OSI model 2) are usually used to process and direct data. Multilayer switches are a type of switch that processes data at the network layer (Layer 3 of the OSI model) and above. A hub is a device used to connect network devices (such as Ethernet devices) to each other to form a single piece of the network. This device works in the physical layer (layer 1 of the OSI model).

What is a switch?

Switches are an important part of modern Ethernet LANs. While small local area networks (small offices or homes) use a switch. Large LANs consist of several managed switches. Managed switches provide solutions such as command line interfaces to manipulate and change how a switch works.

 Switches that work in the data link layer allow devices connected to its ports to communicate by creating separate collision domains for each port without any interference. For example, consider four computers (C1, C2, C3, and C4) that are connected to the network using a 4-port switch. C1 and C2 can communicate with each other, while C3 and C4 can communicate with each other without any interference. Switches can also work in multiple layers at the same time (such as data link, network or transport).

What is a hub?

A hub is also a device used to connect other devices on the network to each other. This is a simple device that emits incoming traffic without any management. This device does not collect any information from the traffic flowing through it, so it does not know anything about the source or destination of this traffic. In a hub, the traffic entering one port exits all other ports.

Because hubs return this traffic to all devices connected to its ports, unnecessary traffic may be sent to devices on the network. Devices themselves must determine whether a packet has been sent to them by checking the address information in each packet. This iterative process can be problematic in a large network with a large volume of traffic flow. The hub can be used in small networks where this iterative process can be controlled.

What is the difference between a switch and a hub?

Although both switches and hubs can be used to connect network components to each other, there are major differences between the two. A hub is a simple device that sends all its incoming traffic to all its ports. This can cause a lot of unnecessary traffic to flow into the network and thus cause a crash. Switches, on the other hand, collect information about connected devices and direct incoming traffic only through the connected port (s).

This feature also allows you to manage the exchanges made through this switch. As a result, hubs are suitable for small networks, and switches are used for large networks with large volumes of traffic exchanged.
