Describe in Detail the Difference Between a Hub and a Switch

Question

Examlex · Accepted Answer

The Answer is A hub and a switch are both networking devices used in a Local Area Network (LAN) to connect multiple devices together. However, they operate in different ways and have different capabilities.

A hub is a simple networking device that works at the physical layer of the OSI model. It receives data from one device and broadcasts it to all other devices connected to the hub. This means that all devices on the network share the same bandwidth, and if multiple devices try to transmit data at the same time, collisions can occur, leading to decreased network performance.

On the other hand, a switch operates at the data link layer of the OSI model and is more intelligent than a hub. A switch learns the MAC addresses of the devices connected to it and only forwards data to the specific device it is intended for. This means that each device on the network has its own dedicated bandwidth, leading to better network performance and less chance of collisions.

Here is a diagram of a hub and a switch:

In the hub diagram, all devices are connected to the hub, and the hub broadcasts data to all devices.

In the switch diagram, each device is connected to the switch, and the switch forwards data only to the intended device.

Now, let's discuss the difference between shared Ethernet and switched Ethernet in light of the differences between a hub and a switch. Shared Ethernet refers to the use of a hub in a network, where all devices share the same bandwidth and collisions can occur. Switched Ethernet, on the other hand, refers to the use of a switch in a network, where each device has its own dedicated bandwidth and collisions are minimized.

In conclusion, the main difference between a hub and a switch in a LAN is the way they handle data transmission. A hub broadcasts data to all devices, leading to shared bandwidth and potential collisions, while a switch forwards data only to the intended device, providing dedicated bandwidth and better network performance. This difference also affects the use of shared Ethernet with a hub and switched Ethernet with a switch in a LAN.
