NIC stands for Network Interface Card. Would allow users to be connected to one another through a wired or wireless. This basically allows two computers to communicate with each of the network or Ethernet.
NIC supports two motions Layer 1 (physical) and layer2 (data link) to provide the physical address of the network between and below the level of mechanisms to deal with the MAC address. MAC address, which is basically an Ethernet, is a unique 48-bit addresses were made for each network card capacity. This is stored in ROM cards. The uniqueness of the IEEE MAC address set.
Don t you have to run Ethernet NIC you installed on your PC. You can work very well with Ring or FDDI, which is also layer 2 First IEEE standards. Most computers these days come with integrated network by adding both chipset motherboard Ethernet or connect to their costs through PCI or Ethernet Chip PCI Express bus. However, NIC can be plugged in, when more network interface is needed.
Public NIC to send data by 10 percent, 100, and 1000 bits per second over twisted-copper wire or Jozi Coaxial BNC cable. Recently, a new vendor using pluggable XFP to 10Gbit per second data transfer speed.
How to transfer data NIC?
NIC transfer data to one or more of the following systems:
1. Vote: CPU NICs on the status of options to see if there is data to be transferred.
2. Putting: NIC interrupts and CPU statistics show ready for transfer.
3. Programmed IO: CPU NICs alerts using to address the system address bus.
4. DMA: Intelligent NIC, which is s own CPU, DMA is used to obtain data directly.
