Network switches 101

 Network switches are an essential component of any modern network. This article is meant to be a starting point for understanding how they work and how they can be used to simplify and improve your network.

What is a network switch?

A network switch allows communication between two nodes or systems in a LAN or WAN infrastructure, including communication between different PCs, printers, routers, other switches, and even firewalls.

Switches allow two computers to connect and exchange data packets with each other. Network switches vary in their build quality, dimensions, and the number of interface offerings. Network switches are available in 8,16,24, 28, and 48-Port ethernet as well as gigabit technology.

Why are network switches critical for IT infrastructures?

First, are they critical? Yes, network switches are considered essential to the IT infrastructure ecosystem, but why?

First, without network switches, the cost of network access and connectivity between various systems, applications, and users would be complex and expensive.

Also, network switches simplify connectivity and access needs by establishing communication between users and systems using physical cable connections like ethernet cables and HDMI over Ethernet cables. Moreover, the network switches can be deployed at any level in the network, like edge, distribution, access, and core network layers.
