Question

Which of the following events is detrimental to an operating system's performance? A. Deadlock B. Interrupt C. Booting Which of the following statements is true? A. Allowing several processes to share time in a multiprogramming system is less efficient than executing each of them to completion one after the other. B. The use of passwords provides an impenetrable safeguard. C. Both A and B D). Neither A not B Which of the following connects existing networks to form an internet? A. Bridge B. Router C. Switch D Repeater If recursion does not have a special terminating case, what error will occur? a) Index out of range b) Illegal argument c) Stack Memory overflow d) No error Which of the following statements about recursion is correct? a) It is not necessary to have a special terminating case in all recursions. b) II is not necessary to simplify the argument in the recursive call c) A recursive solution will always run faster than an equivalent iterative solution d) In many cases, a recursive solution will be easier to understand and to implement than an iterative solution. You need to access values using a key. and the keys must be sorted. Which collection type should you use? a) Tree Map b) ArrayList c) HashMap d) Queue Which sort algorithm starts by cutting the array in half and then recursively sorts each half? a) insertion sort b) selection sort c) merge sort d) quicksort Which of the following is not a means of performing interprocess communication over a network? A. Client/server B. ICANN C. Peer-to-peer

Explanation / Answer

10:

Ans: Deadlock

11:

Ans: D

Allowing several process share time could execute them in efficient way and utilize CPU in better way

Password can be breakable so they are safegurads but not impenetrable.

12:

B:Router

13:

Stack memory overflow.

As in recursion function is been pushed to stack and there is no terminating condition so that stack will overflow.

14:

It is not necessary to simplify the argument in the recursive call.

15:

HashMap

16:

QuickSort

17:

B:ICANN

ICANN, is a nonprofit organization responsible for coordinating the maintenance and procedures of several databases related to the namespaces of the Internet
