Network definition

 Definition: Network

    A network is a group of two or more computers or other electronic devices that are interconnected for the purpose of exchanging data and sharing resources.

    When you buy a new computer, the first thing you’ll probably try to do is connect to the Internet. To do this, you establish a connection to your router, which receives the data from the Internet and then forwards it to the computer.

    Of course that’s not all: Next, you could also connect your printer, smartphone or TV to the router so that these devices are also connected to the Internet. Now you have connected different devices to each other via a central access point and created your own network.

     In information technology, a network is defined as the connection of at least two computer systems, either by a cable or a wireless connection. The simplest network is a combination of two computers connected by a cable. This type of network is called a peer-to-peer network. There is no hierarchy in this network; both participants have equal privileges. Each computer has access to the data of the other device and can share resources such as disk space, applications or peripheral devices (printers, etc.).

    Today’s networks tend to be a bit more complex and don’t just consist of two computers. Systems with more than ten participants usually use client-server networks. In these networks, a central computer (server) provides resources to the other participants in the network (clients).
