**Homework 14th of May- Notes on Network theory**
Wide area network (WAN) on the other hand is used differently and is used to sent emails and data to computers miles away from each other. WAN runs through computer through computer using LAN to get to the computer it wants to. The largest WAN in the world is the internet.**
 * When computers were first made they had no connection with one another, then as technology developed they connected through a network. This is how, in a IT room all the computers connect to just one printer. **Local Area Network (LAN)** is when computers are connected through wires and cables, therefore the two computers would have to be in the same room or at least the same building to be connected. Through LAN emails can be sent and data transferred.
