There are several reasons why the "store and forward network" technique is rarely used in modern communications. One of them is that doing so is no longer feasible?
True or untrue, and provide a short explanation for your answer: When both the transmitter and receiver window widths are 1, the alternating-bit protocol and SR protocol are equivalent.
There are many different reasons why the "store-and-forward network" method is no longer used in ordinary communications today. One of these reasons is because it is no longer practical.
What is Double VLAN tagging (Q-in-Q) and when might it be necessary in network design?
There are a number of reasons why the concept of a "store-and-forward network" is no longer utilised in general communications.
When did the protocols used in wireless LANs first appear, and how did they develop over time?
Explain the concept of multicast and anycast in network protocols. How do they differ from unicast and broadcast, and what applications benefit from these approaches?
What are the interior and exterior routing protocols that are utilised in the majority of today's networks and why are they employed?
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.
