What is Computer Networking?

Computer networking is the practice of connecting computers and devices together to share resources and exchange information. It enables communication and collaboration between devices, such as computers, servers, mobile devices, and other devices connected to the internet.

The most common type of computer network is the Internet, which connects millions of devices worldwide. Other types of networks include local area networks (LANs), wide area networks (WANs), and wireless networks. LANs connect devices in a single location, such as an office or home, while WANs connect devices over a larger geographical area, such as across cities or even countries.

Networking protocols, such as TCP/IP, are used to govern the communication between devices on a network. Network hardware devices, such as routers, switches, and modems, are also used to manage and direct the flow of data across the network.

Computer networking has become increasingly important with the rise of the Internet, cloud computing, and the Internet of Things (IoT), which connects everyday devices to the internet. It plays a key role in enabling various applications such as e-commerce, online gaming, and online communication.
