Which of the following features will characterize an OS as multiprogrammed OS ?
(a) More than one program may be loaded into main memory at the same time.
(b) If a program waits for certain event another program is immediately scheduled.
(c) If the execution of a program terminates, another program is immediately scheduled.
| A. | (a) only |
| B. | (a) and (b) only |
| C. | (a) and (c) only |
| D. | (a), (b) and (c) only |
|
Option: D Explanation : Multiprogramming means more than one program can run simultaneously. In this they share CPU; if one program is terminated for sometime then another can run. If one is using one resource then another can use another resource. Hence option (D) is correct.

C=M*pow(e)modn; n=p*q; edmodf(n)=1; f(n)=(p-1)*(q-1);f(n)=20; e*7mod20=1 ==> e=3; c=5*pow(3)mod33=26; Ans: 26

n= pq = 3 x 11 = 33ø (n) = (p-1) (q-1) = (3-1) (11-1) = 2x 10 = 20ed = 1 mod ø (n)3 x 7 = 1 mod 2021 = 1 mod 20e = 3For encryptionC = M^e mod n = (5)^3 mod 33 = 125 mod 33 = 26
