The term synchronization has many meanings in Computer Science. Within the networking field, the term is usually used to describe making asynchronous communication synchronous (A coordination of activities; running at the same rate) We see synchronization occurring in different layers, but we are mostly concerned with the physical layer and the data link layer (L1 and L2). a) In what ways is synchronization in these two layers similar? b) In what ways is synchronization in these two layers dissimilar?

Why is an Ethernet LAN protocol address field needed? Can you say a beneficial circumstance Where might you either completely ignore the address field, or use a "special" address value in the address field?

Suppose a switch is built using a computer workstation and that it can forward packets at a rate of 500,000 packets per second, regardless (within limits) of size. Assume the workstation uses direct memory access (DMA) to move data in and out of its main memory, which has a bandwidth of 2 Gbps, and that the I/O bus has a bandwidth of 1 Gbps. At what packet size would the bus bandwidth become the limiting factor?

Configure the OSPF process on all routers for a single area-0 (backbone) and advertise its directly related networks.on R1

TCP sockets handle data sent as a byte stream, but UDP sockets are aware of message boundaries.What are the advantages and disadvantages of a byte-oriented API versus an AP that recognises and preserves application-defined message boundaries?

Suppose an extension of TCP allows window size much larger than 64 KB. Assume the extended TCP runs over a 100-Mbps link with RTT 100 ms, segment size is 1 KB, and receiving window size is 1 MB. How long does it take to send a 200 KB file?
