This article will introduce you to what is network switching, including its core and basic concepts, differences, and more. 

What is Network Switching?

It is a method of interconnecting multiple devices on a computer network. It allows users to share resources like printers and hard drives so that they can communicate with one another over the Internet or other types of networks. Switching is a method of interconnecting multiple devices on a computer network. It differs from routing in that it doesn't involve forwarding traffic between networks; instead, it allows users on one local area network (LAN) segment to communicate directly with users on another LAN segment without having their data pass through any intermediate nodes or routers first

What is a Switch?

A switch is a hardware device that connects multiple computers and other devices. Switches are the most common type of network hardware device, and they're used to connect everything from small home offices to large corporations. 

Switches are a key technology in computer networks. They allow computers to communicate with each other, and they consist of a set of ports that can be connected using wires or wireless signals. Switches are used in corporate LANs (local area networks) as well as home networks. Like any other piece of hardware, it's important to choose the right switch for your needs.

How does a Switch Work?

The question of what is network switching is directly related to its building blocks of switches which are used to connect multiple computers and other devices, while routers are used to connect networks. Switches operate at Layer 2 of the OSI model (the data link layer) whereas routers operate at Layer 3 (the network layer). Switches are used to connect multiple devices, such as computers and printers. Routers are used to connect networks, such as your home network with the internet.

Switching Modes in Switches

Hub Mode: In this mode, the switch acts as a hub and all the incoming data packets are broadcasted to all other ports.

Bridge Mode: In this mode, switches are capable of learning MAC addresses by examining the source address of incoming frames and then forwarding them accordingly. Switches also support VLANs so that they can be divided into different segments with different traffic patterns.

Repeater Mode: This mode allows two hosts connected to two separate switches to communicate with each other without having any configuration changes made on either end device or switch itself; however, this method does not scale well because it requires manual configuration for each client-to-client connection made between hosts connected through multiple devices (switches).

How do Switches differ from a Hub?

A switch is a device that connects multiple computers and other devices. A hub, on the other hand, is a device that connects several computers and other devices. A network switch does not have to pass all the data from one computer to another--it can filter it selectively as needed. This means that switches are more efficient than hubs when it comes to handling large amounts of traffic on your local area network (LAN).

How are Switches different from a Router?

Switches are used to connect multiple computers and other devices, while routers are used to connect networks. Switches use a technology called switch-to-switch forwarding that helps them determine the best path for sending data packets between ports based on the destination address in each packet. Routers use another method called hop-by-hop routing (also known as layer 3 or IP routing), which involves determining how best to get from one endpoint on one network to another endpoint on another network.

Switches also differ from routers in that they do not typically connect two networks; rather, switches are used within one network to connect multiple devices at high speeds for increased performance and reliability over long distances with minimal collisions between multiple users sharing bandwidth resources simultaneously. 


This concludes the topic of “what is network switching” and other related concepts. Switches are an important part of any network. They allow for faster and more reliable data transfer between computers and other devices on your network. As you can see from this article, switches are similar to routers in many ways but some key differences between them make each device uniquely suited for certain situations.
