3.4A Types of Computing Networks

What a Network Is

A computer network is two or more devices linked so they can share data and resources (e.g. a phone joining home wi-fi, a laptop connecting to a printer).

Once machines are linked into a connected system, they can pass data between them. Email, the web and streaming all depend on data moving between devices.

Three ways to classify networks: by connection medium, by size, and by architecture.

By Connection: Wired, Wireless, Cloud

A wired network uses cables (copper or fibre): fast, stable, secure, but ties devices to a socket and costs more to install.

A wireless network sends data via radio waves: mobile, quick and cheap to set up, but signals can be blocked or intercepted, and are usually slower.

A cloud network runs data and services on remote servers reached over the internet: easy to scale, but depends on a reliable connection and on trusting the server operator.

Most real networks blend all three at once: a wired link into the building, wi-fi around the house, and cloud services holding the files.

By Size: PAN to WAN
