• Lan is commonly abbreviated as Local Area Network LAN is a computer network whose network only covers a small area, such as campus computer networks, buildings, offices, in homes, schools or smaller. Today, most LAN based on IEEE 802.3 Ethernet technologies using a switch device, which has a data transfer speed 10, 100, or 1000 Mbit / s. In addition to Ethernet technology, current technology, 802.11b (often called Wi-fi) is also often used to form a LAN. Places that provide a LAN connection with a technology called Wi-Fi hotspots.

On a LAN, each node or computer has the computing power of its own, different from the concept of terminal dump. Each computer can also access resources on the LAN in accordance with the access rights that have been arranged. Resources can be data or devices such as printers. On a LAN, a user can also communicate with other users by using the appropriate application.
