WITH EXPERT-CURATED QUESTIONS AND
PRECISE ANSWERS ALREADY PASSED
◉Broadcast Channels . Ans: Connect multiple hosts in wireless LANs,
satellite networks, and HFC access networks
◉Medium Access Protocol . Ans: Coordinates frame transmission in
broadcast channels with multiple hosts
◉Point-to-Point Communication Link . Ans: Direct link between two
nodes, simpler to coordinate access compared to broadcast channels
◉Frame . Ans: Structure encapsulating network-layer datagrams in link-
layer protocols
◉Link Access . Ans: Rules specified by MAC protocol for transmitting
frames onto the link
, ◉Reliable Delivery . Ans: Link-layer service ensuring error-free
movement of datagrams across the link
◉Error Detection and Correction . Ans: Mechanism to detect and correct
bit errors introduced by signal attenuation and noise
◉Internet Checksum . Ans: Limited error detection provided by the
Internet's transport and network layers
◉Link-Layer Implementation . Ans: Implemented in a host's hardware
or software, often on a separate card or chip
◉Line Card . Ans: Hardware component where the link layer is
implemented in a router
◉Link Layer Controller . Ans: Implements framing, link access, error
detection in hardware.
◉Network Adapter . Ans: Attaches to host's bus, implements link-layer
services.
◉LAN-on-motherboard . Ans: Integration of network adapter onto host's
motherboard.
