Switch Router Hub are the main terminologies use in Computer Science in the field of networking. Many of us peoples are confuse about their working and functionalities and their difference between them.
Today we discuss about there concepts in details with the help of pictures and videos.
Switch Working & Functionalities
What is Switch ?
A network switch is a computer networking device that connects devices together on a computer network, by using packet switching to receive, process and forward data to the destination device.
How Switch Works ?
In the most basic networks, devices are connected with hubs. But there’s a limit to the amount of bandwidth users can share on a hub-based network. The amount of time data takes to get to its destination increases on hub networks as more devices are added. A switch avoids these and other limitations of hub networks.

Hub Working & Functionalities
What is Hub ?
A hub is a common connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Router Works & Functionalities
What is Router ?
A router is a networking device that forwards data packets between computer networks. Routers perform the “traffic directing” functions on the Internet. A data packet is typically forwarded from one router to another through the networks that constitute the inter network until it reaches its destination node.
How Router Works ?
Routing is the process of forwarding IP packets from one network to another. A router is a device that joins networks together and routes traffic between them. A router will have at least two network cards (NICs), one physically connected to one network and the other physically connected to another network.
