What is a Computer Network?

A computer network is a group of two or more computers that are connected together to share resources and communicate with each other. Computers in a network can be connected using a variety of technologies, including cables, wires, and Wi-Fi.

Types of Computer Networks

There are two main types of computer networks:

  • Local area networks (LANs): LANs are small networks that are typically limited to a single building or campus. LANs are often used to connect computers in homes, offices, and schools.
  • Wide area networks (WANs): WANs are large networks that can span cities, countries, or even the entire world. WANs are often used to connect businesses, government agencies, and educational institutions.

Components of a Computer Network

A computer network typically consists of the following components:

  • Computers: The computers in a network are the devices that use the network to share resources and communicate with each other.
  • Networking devices: Networking devices are used to connect computers together and to manage traffic on the network. Networking devices include routers, switches, and hubs.
  • Cabling: Cabling is used to connect computers and networking devices together. Cabling can be made of copper or fiber optic cable.
  • Software: Software is used to manage the network and to provide services to the computers on the network. Networking software includes operating systems, network protocols, and applications.

Benefits of Computer Networks

There are many benefits to using computer networks, including:

  • Resource sharing: Computer networks allow users to share resources such as files, printers, and Internet access. This can save businesses money and improve productivity.
