How GATE tests Data Link Layer

Medium Access Control (MAC) in GATE CS is predominantly tested through quantitative numerical problems and conceptual protocol comparisons. The focus is split between random access protocols (CSMA/CD collision detection constraints and slotted ALOHA transmission probabilities), controlled access (Token Ring round-trip delays and token holding limits), and wireless MAC protocols (IEEE 802.11 CSMA/CA features, channels, and ACK mechanisms). Most questions carry 2 marks and appear in NAT format requiring unit conversions.
