What is Hub in Computer Network

Hub is a networking device that connects multiple Ethernet devices together and making them act as a single network segment. It works at the physical layer (Layer 1) of the OSI Model. A repeater hub also engages in collision detection, forwarding a jam signal to all ports when it detects the collision. I am going to explain What is Hub in Computer Network and how does it works so keep reading this article till the end.

Some hubs also called as Repeater hub, Ethernet hub, active hub,
and the network hub all these are categorized according to their working, specification and features.
Hub Operate at half-duplex mode as it cannot send and receive the data simultaneously, It can only send or receive the data at a time both things are not allowed in the hub but in the case of a switch, It allows to send and receive the data simultaneously.
Hub has a separate collision domain, so the collision chances and loss of data increase that's why Hub is obsoleted from the market.

How to Construction of Hub

Physically Hub is a small box that is in the rectangular shape having multiple ports for connecting various devices to it. It receives its power supply from the auxiliary power sources and receives incoming data signals, amplifies them in the form of an electrical signal and then sends it to each connected device.
