Q12.
What is the output of tho following program? main(){ int x=2, y=5; if(x < y) return (x=x+y); else printf("z1"); printf("z2"); }Q13.
Assume A and B are non-zero positive integers. The following code segment: while(A!=B){ if(A > B) A -= B; else B -= A; } cout << A; // printing the value of AQ14.
StationA uses 32 byte packets to transmit messages to Station B using a sliding window protocol. The round trip delay between A and B is 80 ms and the bottleneck bandwidth on the path between A and B is 128 kbps. What is the optimal window size that A should use?Q15.
________ can detect burst error of length less than or equal to degree of the polynomial and detects burst errors that affect odd number of bits.Q16.
Consider a system having m resources of the same type. These resources are shared by 3 processes A,B,C, which have peak time demands of 3,4,6 respectively. The minimum value of m that ensures that deadlock will never occur is:Q17.
Disk requests come to a disk driver for cylinders in the order 10, 22, 20, 2, 40, 6 and 38 at a time when the disk drive is reading from cylinder 20. The seek time is 6 ms/cylinder. The total seek time, if the disk arm scheduling algorithms is first-come-first-served isQ18.
Any set of Boolean operation that is sufficient to represent all Boolean expression is said to be complete. Which of the following is not complete ?Q19.
In the diagram above, the inverter (NOT gate) and the AND-gates labeled 1 and 2 have delays of 9, 10 and 12 nanoseconds (ns), respectively. Wire delays are negligible. For certain values a and c, together with certain transition of b, a glitch (spurious output) is generated for a short time, after which the output assumes its correct value. The duration of glitch is:
