A computer network is a group of computers and other devices connected together to share resources and communicate with each other. Networks can be used for a variety of purposes, such as sharing files and printers, accessing the internet, and collaborating on projects. There are different types of computer networks, such as local area networks (LANs), which are used in homes, schools, and small businesses, and wide area networks (WANs), which connect multiple LANs over larger geographic areas. Networks can be wired, using Ethernet cables, or wireless, using Wi-Fi technology.
