Computer networks enable units like computers, printers, and servers to connect, communicate, and share resources including files and internet access. They may be as small as two personal computers in a home or office, or perhaps as large as a global network of millions of gadgets. Wireless indicators or cabling, or a combination of the two, connect the networked products.
Servers are highly effective computers that host and manage data and applications for the different devices (known as clients) connected to them. Servers present many benefits, which include increased memory space and central data management. They also help lessen errors by giving a single supply of truth for facts, and improve security by simply implementing detailed data back-up systems.
LANs are a type of computer network that connects equipment within a tiny geographical area, such as a organization, school, or home. The devices are often connected by twisted-pair or coaxial cable, and have high speed connections. This enables users to talk about equipment, including printers, and copy large amounts of information at high speed. LANs are likewise easy to extend.
WANs tend to be complex, joining multiple neighborhood and metropolitan networks. They use routers, links, and changes to convert data in packets, which can be then shifted across the network.

This is made possible by the same technology that renders the internet function, which will relies on a series of layered protocols to procedure and deliver data.
