Response Details:
Dear User,
  • LAN interface handles the following details of frame transmission and reception -
    • Adds hardware addresses, error detection codes, etc. to outgoing frames
    • May use DMA to copy frame data directly from main memory
    • Obeys access rules (e.g., CSMA/CD) when transmitting
    • Checks error detection codes on incoming frames
    • May use DMA to copy data directly into main memory
    • Checks destination address on incoming frames
  • If destination address on incoming frame matches the local station's address, a copy of the frame is passed to the attached computer
  • Frames not addressed to the local computer are ignored and don't affect the local computer in any way
Hope this helps you
