Computer network, also known as networking, is the practice of connecting multiple computing devices together, such as computers, servers, printers, routers, and other electronic devices, for the purpose of sharing information, resources, and communication. With the addition of the internet, computer networking has become an important part of today’s information technology infrastructure.
A computer network is a set of connected devices that can exchange data with one another without user intervention. Networks can be either wired, using cables to connect computers or wireless, using either radio frequency waves, infrared, or microwaves. The internet is one of the most common computer networks, made up of millions of devices connected to one another around the world.
Computer networking is important not only for businesses, but also for individuals who may want to share files, music, and photos with one another, or who may be interested in distance learning or telecommuting. Networks also enable ecommerce activity and enable telecommunications service providers to deliver services and content, such as television and movies.
Computer networks may be divided into several types. Local area networks (LANs) are networks that exist within a single building or campus. Wide area networks (WANs) are networks that extend over a larger geographic area than a LAN. The internet is also considered to be a WAN. Wireless local area networks (WLANs) are networks where wireless technology is used to connect different systems.
Computer networks involve the use of protocols, which are rules that govern how data is shared. Common network protocols include Ethernet, TCP/IP (Transmission Control Protocol/Internet Protocol), and Wi-Fi (Wireless Fidelity). These protocols enable different types of networks to exchange information and function properly.
Computer networking has revolutionized the computing industry, making it much easier for users to access data, share files, and communicate with one another. Network technology is an essential part of the modern day enterprise and is used by companies and individuals alike.
