While opening a TCP connection, the initial sequence number is to be derived using a time-of-day (ToD) clock that keeps running even when the host is down. The low order 32 bits of the counter of the ToD clock is to be used for the initial sequence numbers. The clock counters increments once per millisecond. The maximum packet lifetime is given to be 64s. Which one of the choices given below is closest to the minimum permissible rate at which sequence numbers used for packets of a connection can increase?
Which one of the choices given below is closest to the minimum permissible rate at which sequence numbers used for packets of a connection can increase?
Option A. 0.015/s Option B. 0.064/s Option C. 0.135/s Option D. 0.327/s True Answer A
Solution: The maximum packet lifetime is given to be 64 seconds in the question. Thus, a sequence number increments after every 64 seconds. So, minimum permissible rate = 1 / 64 = 0.015 per second

In the following process state transition diagram for a uniprocessor system, assume that there are always some processes in the ready state:
Now consider the following statements: I. If a process makes a transition D, it would result in another process making transition A immediately. II. A process P2 in blocked state can make transition E while another process P1 is in running state. III. The OS uses preemptive scheduling. IV. The OS uses non-preemptive scheduling. Which of the above statements are TRUE?
Option A. I and II Option B. I and III Option C. II and III Option D. II and IV True Answer C
Solution: In preemptive scheduling the process which allocated the CPU keeps it and release it only when it switching to waiting state. Also a process P2 in blocked state can make transition E while other process P1 in running Alternately A process P2 in blocked state can make transition E while another P1 is in running state. The OS uses preemptive Scheduling.
Option A. 3, 0, and 1 Option B. 3, 3, and 3 Option C. 4, 0, and 1 Option D. 3, 0, and 2 True Answer A
Therefore, the maximum and minimum chain length is 3 & 0 respectively. Average chain length = (0 + 3 + 1 + 1 + 0 + 1 + 2 + 0 + 1)/9 = 1.

Complete the sentence:
Universalism is to particularism as diffuseness is to _______________.
Option A. Specificity Option B. Neutrality Option C. Generality Option D. Adaptation True Answer A
Universalism is almost an opposite word of Particularism. So we need to find the opposite word (antonym) of Diffuseness.
Diffuseness is nature of spreading. Specificity may be the nearest answer.

When there is a miss in L1 cache and a hit in L2 cache, a block is transferred from L2 cache to L1 cache. What is the time taken for this transfer?
A computer system has an L1 cache, an L2 cache, and a main memory unit connected as shown below. The block size in L1 cache is 4 words. The block size in L2 cache is 16 words. The memory access times are 2 nanoseconds. 20 nanoseconds and 200 nanoseconds for L1 cache, L2 cache and main memory unit respectively.
Option A. 2 nanoseconds Option B. 20 nanoseconds Option C. 22 nanoseconds Option D. 88 nanoseconds True Answer D
A block is transferred from L2 to L1. And L1 block size being 4 words (since L1 is requesting we need to consider L1 block size and not L2 block size) and data width being 4 bytes, it requires 4 L2 access (for read) and 4 L1 access (for store). So, time = (20+2)*4 = 88 ns.
Option A. Ctrl + Shift + O Option B. Ctrl + shift + P Option C. Ctrl + F2 Option D. Ctrl + P True Answer A
