WAN stands for Wide Area Network which is a term in the field of network computer technology. WAN is a computer network that already covers a very wide area and even has become a global network throughout the world. For example, the WAN will happen when a computer is connected to another computer in a region or a computer that is connected to each other in a company which has several branches all over the world. WAN itself is often used for public communication channels such as we know that WANs are global, so the most important goal in making the WAN is for communication between communities.

LAN or Local Area Network is a small part of the WAN, the most fundamental differences between the LAN and WAN is in a network coverage area. Examples of LAN is a network in the office, campus and school. Often we know that there are computers in the office or at school / college are connected but not connected with the outside world as to the office or to another school. However, when viewed in a functional LAN and WAN have other differences between

1. Having LAN high data rapidly for a local LAN that can be practically little

2. LAN only requires a small fee, no need to hire a telecommunications service to connect with the outside world.

3. LAN terminal spacing is not too far

4. LAN only is privacy or property of one organization and one person

5. Data transfer speed is independent of the telecommunications network

6. Using a wire transmission medium for communicating
