Question 64

What is the function of following UNIX command ?

WC – l <a  >b&

• It runs the word count program to count the number of lines in its input, a, writing the result to b, as a foreground process.
• It runs the word count program to count the number of lines in its input, a, writing the result to b, but does it in the background.
• It counts the errors during the execution of a process, a, and puts the result in process b.
• It copies the ‘l’ numbers of lines of program from file, a, and stores in file b.

Question 65

Consider the statement, “Either – 2 ≤ x ≤ – 1 or 1 ≤ x ≤2”. The negation of this statement is

• x < – 2 or 2 < x or – 1 < x < 1
  
• x < – 2 or 2 < x
  
• – 1 < x < 1
  
• x ≤ – 2 or 2 < x or – 1 < x < 1

Question 66

Which of the following is characteristic of an MIS?

• Provides guidance in identifying problems, finding and evaluating alternative solutions, and selecting or comparing alternatives.
• Draws on diverse yet predictable data resources to aggregate and summarize data.
• High volume, data capture focus.
• Has as its goal the efficiency of data movement and processing and interfacing different TPS.

Question 67

How does randomized hill-climbing choose the next move each time?

• It generates a random move from the moveset, and accepts this move.
• It generates a random move from the whole state space, and accepts this move.
• It generates a random move from the moveset, and accepts this move only if this move improves the evaluation function.
• It generates a random move from the whole state space, and accepts this move only if this move improves the evaluation function.
