What is the difference between a hub and a switch?

A Hub is a networking device that allows you to connect multiple PCs to a single network, whereas a Switch connects various devices together on a single computer network. A Hub operates on the physical layer, whereas Switch operates on the data link layer.

What are the 3 basic hub types?

There are three types of network hubs: passive, active, and intelligent. network. They do not improve the performance of local area networks (LANs), and may limit maximum media distances. Typically, passive hubs are connected to other devices in a star configuration.

What is an intelligent hub?

Why use a hub over a switch?

Switches can operate at multiple data rates, operate at either half- or full-duplex, and can automatically set speed and duplex using the auto-negotiation protocol. … In that situation, hubs have a particular feature that is important for network diagnostics, making a hub a better option than a switch.

How does a hub work?

When a hub receives a packet of data (an Ethernet frame) at one of its ports from a network device, it transmits (repeats) the packet to all of its ports to all of the other network devices. … Hubs operate in such a way that all data received through one port is sent to all other ports.
