41. Which is also known as a connectionless protocol for a packet-switching network that uses the Datagram approach?
IPV5 and IPV6 are also Internet Protocol versions, but they are not specifically known for being connectionless or using the Datagram approach. Therefore, option B, IPV4, is the correct choice in this context.
Solution:
IPV4 (Internet Protocol version 4) is a connectionless protocol used in packet-switching networks. It is the most widely used version of the Internet Protocol. IPV4 uses the Datagram approach, where data is divided into small packets, each packet is individually routed to its destination, and packets can take different paths to reach the destination. The packets are then reassembled at the destination to form the complete data. IPV5 and IPV6 are also Internet Protocol versions, but they are not specifically known for being connectionless or using the Datagram approach. Therefore, option B, IPV4, is the correct choice in this context.
42. Which switch is a multistage switch with micro switches at each stage that route the packets based on the output port represented as a binary string?
44. A station in a network forwards incoming packets by placing them on its shortest output queue. What routing algorithm is being used?
45. The probability that a single bit will be in error on a typical public telephone line using 4800 bps modem is 10 to the power -3. If no error detection mechanism is used, the residual error rate for a communication line using 9-bit frames is approximately
47. Which of the following condition is used to transmit two packets over a medium at the same time?
48. You have a class A network address 10.0.0.0 with 40 subnets, but are required to add 60 new subnets very soon. You would like to still allow for the largest possible number of host IDs per subnet. Which subnet mask should you assign?
