The network card is the "network interface card", referred to as the network card, the English name is Network Interface Card, referred to as NIC, also known as the network adapter (NIA-Network Interface Adapter). It is used to realize the physical connection between networked computers and network cables, and provide a physical channel for communication between computers, and high-speed data transmission through this channel.
In a local area network, each networked computer needs to install one or more network cards, and connect the computer to the network cable system through a media connector. The network card completes most of the functions of the physical layer and the data link layer, including the physical connection of the network card and the network cable, media access control (such as: CSMA / CD), disassembly and assembly of data frames, frame transmission and reception, error checking, Data signal encoding / decoding (such as: Manchester code conversion), data serial, parallel conversion and other functions.
A network card is one of the most basic components in a local area network. It is a hardware device that connects a computer to a network. Whether it is a twisted pair connection, a coaxial cable connection or a fiber connection, you must use a network card to achieve data communication.
The main working principle of the network card is to organize the data sent from the computer to the network line, and decompose the data into data packets of appropriate size and send them to the network. For the network card, each network card has a unique network node address, which is burned into the ROM (read only memory chip) by the network card manufacturer during production. We call it the MAC address (physical address), and guarantee Never repeat.
The network cards we use every day are Ethernet network cards. At present, the network card can be divided into 10M network card, 10 / 100M adaptive network card and Gigabit (1000M) network card according to its transmission speed. If it is just for general use, such as daily office, it is more suitable to use 10M network card and 10 / 100M adaptive network card. If it is used in server and other product areas, it is necessary to choose a gigabit network card.
