What is network?
A basic network consists of a collection of computers and other hardware devices such as printers and scanners that are linked together so that they can communicate with each other.

Pieces of hardware that are needed to turn stand-alone computers into networked computers.
Hub- Simple device which is used to join computers in a network so that they are able to share files and an internet connection.
- Similar to hubs in that they are used to join multiple computers together in a network.
- Switches, however, contain more intelligence because they are able to inspect packets of data so that they are forwarded appropriately.
- Because a switch only sends a packet of data to the computer it is intended for, it reduces the amount of data on the network, hence speeding the network up.
- Usually a combination of hardware and software which often act as gateways so that small home computer networks can be connected to the internet using a single connection.
