What is a Switch?
A network switch is a computer networking device that connects various devices together on a single computer network. It may also be used to route information in the form of electronic data sent over networks. Since the process of linking network segments is also called bridging, switches are usually referred to as bridging devices.
Types of HUB
Here are two types of Hub:
Active Hub:- Active hub is a kind of hub which have their own power supply. It can clean, improve, and relay the signal along with the network. It works as a repeater as well as a wiring center. They are also used as an extension for two or more nodes.
Passive Hub: This type of hub collects power supply from the active hub and wiring from nodes. Passive hubs relay signals into the network without cleaning and boosting them. It can't be used to extend the distance between nodes.
Type of Switch
Manageable Switches: Manageable switch has a console port and IP address, which can be assigned and configured.
Unmanageable Switches: On an Unmanageable switch, configuration can't be made. It is not possible to assign IP address as there is no console port.
Features of Hub
Here, are important features of Hub:
It works with broadcasting and shared bandwidth.
It has 1 broadcast domain and 1 collision domain
Works at the physical layer of the OSI model
A virtual LAN can't be created using a hub
Provides support for half-duplex transmission mode
A hub has just a single broadcast domain
Does not support spanning tree protocol
Packet collisions occur mostly inside a hub
