Understanding Different Networking Concepts
A network consists of computers and other electronic devices that are connected to each other over a transmission medium. The transmission medium can be cable (copper or optical fibre), Wi-Fi, radio waves, infrared waves, or a satellite.
There are many benefits of computer networks such as higher speed, reduced cost, enhanced security, flexible access, email access, and centralised software and hardware management.
A network allows users to share both software and hardware such as printers, scanners, and applications. Each device on the network is referred to as a node, and each node has a unique network address. Some computer networks also have a server that is used to manage various networking resources. A server is a computer that functions as a central repository for storing files and running programs centrally. It processes requests and sends data to other computers (clients) over a local network or the Internet.
