Router and Switch:
Are you familiar with the terms "router" and "switch"? If not, worry not! These are basic networking terms used to describe fundamental networking devices. Understanding these two essential networking devices and how they work is vital for anyone interested in getting into the field of computer networking, or if you simply want to improve your home network.
So, what exactly is the difference between a router and switch? A router is a device that connects multiple networks together (probably the internet and your home network) and directs traffic between them. Meanwhile, a switch is a device that manages and distributes network traffic between various devices attached to a network.
Routers and Switches are both essential in computer networking. For instance, without a router, your computer may be connected to the internet, but without a local network such as a switch, you'll only be connected to your computer. A switch can further connect your computer to other devices on your network, such as printers, cameras, and other computers, by managing the distribution of data.
One of the most significant distinctions between a switch and a router is the OSI (Open Systems Interconnection) model level on which they operate. In essence, switches are Layer 2 devices that use the MAC (Media Access Control) address to forward data to its intended recipient. Routers, on the other hand, are considered to be Layer 3 devices that use IP (Internet Protocol) addresses to identify and forward data to their intended recipient.
In summary, while both routers and switches are crucial networking devices that direct network traffic, a switch is responsible for managing and distributing network traffic within a local network, while a router directs traffic between networks.
