What is a computer network?

A computer network is a group of two or more connected computers which are able to share data, resources, and information. An example of a computer network is the internet, which connects millions of computers around the world. Computer networks allow for a variety of services such as email, streaming video, and gaming. Additionally, they are used to connect computers in the same building, such as those in a school or a business. One fun fact about computer networks is that the internet is made up of over 50,000 networks, which are connected to each other to form the network of networks known as the internet.
