This document contains two sets of questions for a computer networks unit test. Set A includes questions about controlled access protocols, protocols that use pipelining in data link control, common gigabit Ethernet standards, the PPP frame format, and the need for framing. It also asks to explain the stop and wait ARQ protocol and slotted ALOHA protocol. Set B includes questions about random access protocols, piggybacking, common Ethernet standards, HDLC, and collisions. It also asks to explain pure ALOHA, Go Back N ARQ, Bluetooth, and CSMA/CA.
