Kurose and Ross Edition 6 Exercise 3 Question R7 (Page No 286)
Suppose a process in Host C has a UDP socket with port number 6789. Suppose both Host A and Host B each send a UDP segment to Host C with destination port number 6789. Will both of these segments be directed to the same ... Host C? If so, how will the process at Host C know that these two segments originated from two different hosts?

Consider an instance of TCP's Additive Increase Multiplicative Decrease (AIMD) algorithm where the window size at the start of slow start phase is 2 MSS and the threshold at the start of 1 st transmission is 16 MSS. Assume TCP use over a lossy link i.e., timeout ... window at the start of slow start phase is 2 MSS ;so when timeout occur should'nt we start with window size of 2 MSS]

doubt
A machine has a 32-bit architecture, with 1-word long instructions. It has 64 registers, each of which is 32 bits long. It needs to support 45 instructions, which have an immediate operand in addition to two register operands. Assuming that the immediate ... we use signed 2's complement instead of unsigned integer then what will be the maximum and minimum value of the immediate operand ?

a) Assume each router implements FIFO queuing. If each flow consists of an identical, 1-Mbps constant bit rate UDP flow with equal packet sizes, what will the resulting rate be for each flow? You can assume that FIFO drops packets with uniform probability. ... is assigned a weight equal to its number (i.e., flow F4 gets weight 4). What are the resulting throughputs?

general conceptual doubt
Why increase in cache size doesnt affect conflict misses?? According to me when we will increase cache size number of blocks will increase and hence lesser no of conflicts will be there because less number of main memory blocks will contend for same cache line?? But its said that conflict miss is independent of cache size how?? This seems so confusing to me.
