Network Interface Card and Its Main Function
The network interface card (NIC) is also called network interface controller, network adapter, network card or net card, which is one of the most basic components in the local area network (LAN). It is designed to communicate the computer with the network. No matter through what kind of connections, twisted pair, coaxial cable, or fiber optic, the data communication only can be achieved with the help of a net card. Similar to the sound card and other devices, a NIC card should has its own drivers to match it.
The main function of a network adapter is to pick up the data, send it to network cables from the computer, divide the data into appropriate packets and send them to the network so as to allow the computer to access that network. Each NIC card has a ROM chip that contains a unique number, the media access control (MAC) Address that is permanent. The MAC address identifies the device uniquely on the LAN.
Currently, the most commonly used net card in our daily life is the Ethernet network card. According to its transmission rate, we can divide the net card into three types: 10M NIC card, 10/100M fast net card and 1000M network card.
If you only use your network adapter for a general purpose, such as used in normal office work, the 10M or the 10/100M network adapter is suitable for you, but if used in the servers and other areas, you should choose the 1000M network adapter.
