This course covers various computer networking topics including data transfer rates, layered protocols, semaphore usage, connection handling, delay-bandwidth product, Aloha system comparison, network configuration, secure communication protocol design, and functions of repeaters, bridges, routers, and gateways. It also covers LAN characteristics, connection-oriented vs connectionless systems, MAC protocol efficiency comparison, token ring recovery process, IPv4 address classes, subnet calculation, and ARP vs RARP. The course addresses questions such as the range for higher data rates than 300 Mbps cable, pros and cons of layered protocols, semaphore usage in networking, client program operation and result handling, importance of delay-bandwidth product in network efficiency, time to send a 1 KB file over high-speed cable and through 20 routers, definition of Aloha system and comparison with turn-based transmission, network configuration for 25 PCs with Ethernet, hybrid data link protoc

error rate is generally low, otherwise (when the error rate is high) it is willing to let the receiver use ARQ if need arises. The data link layer protocol, thus, requires to be a hybrid one such that it could adaptively switch back and forth between FEC and ARQ modes as needed. Design (specify steps and functions) such a hybrid protocol defending any non- trivial design choice you lean on. The bit error rate could dynamically change within the interval of 10^(-2) to 10^(-8).
with that of a CSMA/CD system. Under what conditions one is better than the other?
