1. Name the advantages of optical fiber over twisted-pair and coaxial cable. 2. Compare and contrast (major points) between a circuit-switched network and a packet-switched network. 3. The two types of networks, datagram and virtual-circuit, need a routing or switching table to find the output port from which the information belonging to a destination should be sent out, but a circuit-switched network has no need for such a table. Give the reason for this difference. 4. What is the Hamming distance for each of the following codewords: a. d (10000, 00100) b. d (00101, 10000) 5. Find the minimum Hamming distance for the following cases: a. Detection of two errors. b. Correction of three errors. c. Detection of 3 errors or correction of 2 errors. …
