Consider a cache with 128 blocks of 16 words each. CPU generates 16 bit address. What is the tag size if 4-way set associative mapping is used ?
Question 3
The chromatic number of a complete bipartite graph K8 is _____________.
Question 4
Host A is sending data to host B over a full duplex link. A and B are using the sliding window protocol for flow control. The send and receive window sizes are 5 packets each. Data packets (sent only from A to B) are all 1000 bytes long and the transmission time for such a packet is 50 ps. Acknowledgment packets (sent only from B to A), are very small and require negligible transmission time. The propagation delay over the link is 200 is. What is the maximum achievable throughput in this communication?

Question 7
Let A1, A2, A3, and A4 be four matrices of dimensions 10 x 5, 5 x 20, 20 x 10, and 10 x 5, respectively. The minimum number of scalar multiplications required to find the product A1A2A3A4 using the basic matrix multiplication method is
Question 8
The following C function takes a single-linked list of integers as a parameter and rearranges the elements of the list. The function is called with the list containing the integers 1, 2, 3, 4, 5 in the given order. What will be the contents of the list after the function completes execution? void rearrange (struct node *ptr) { int temp; while(ptr) { temp = ptr->value; p->value = ((ptr->value)++); p->value = temp; ptr++ } }
