Topic notes
In this topic area within Computer Networks, GATE tests foundational conceptual knowledge through direct 1-mark multiple-choice questions. The questions focus on matching standard network applications to their corresponding underlying transport layer protocols (TCP vs. UDP) and identifying key-usage sequences in secure transmission protocols involving digital signatures and asymmetric encryption. The emphasis is on testing functional understanding of protocol services and layered security mechanisms.
Full Switching and Performance Metrics guide →Consider a 100 Mbps link between an earth station (sender) and a satellite (receiver) at an altitude of 2100 km. The signal propagates at a speed of 3 108 m/s. The time taken (in milliseconds, *rounded off to two decimal places*) for the receiver to completely receive a packet of 1000 bytes transmitted by the sender is …
