Network Interface
Local Area Network (LAN)
LAN is a computer network that covers a local area, such as a home, office or group of buildings. LANs now use more technology based on the IEEE 802.3 Ethernet switch, or with Wi-Fi. Passable running at speeds of 10, 100, or 1000 Mbps.
The striking difference between Local Area Network (LAN) and Wide Area Network (WAN) uses more data, only for small areas, and does not require network leases.
Which is now widely used in the physical layer by using TCP / IP as a protocol, there are many other devices that can be used to build LAN. LANs can be connected to other LANs using routers and leased lines to form WANs. In addition, it can be connected to the internet and can connect with other LANs by using tunnels and VPN technology.
Most used devices LAN:

Ethernet and IEEE 802.x Local Area Network The most widely used network devices with IEEE 802.3 standardization, the data format can be seen in Figures in
image Frame format for Ethernet and IEEE 802.3
In the data link layer used IEEE 802.2 is Logical Link Controler (LLC) which is used in Media Access Control (MAC).
Some Ethernet technologies such as in Fig following

For Ethernet technology used the format:
[x] [y] [z]
Example: 10BaseT, which means 10, is the speed with Mbps units. In addition, there are also 100, 1000 Base, is a technology used in the form of Baseband. In addition, there is also Broadband T, is Twisted Pair, where the media used is twisted pair (twisted pair)
