LAN INTERFACE:

 LAN interface operates all details of frame reception and transmission which are shown as follows:

  • It includes hardware error detection, addresses codes, etc. to outgoing frames.
  • It can use DMA to copy frame data directly from main storage.
  • It obeys accessing rules (e.g., CSMA/CD) when transmitting.
  • It detects error detection codes on incoming frames.
  • It can use DMA to copy data directly into storage.
  • It detects destination address on incoming frames.
  • The frames not addressed to the local device are ignored and don't affect

       the local device in any way.
