Suppose a computer can execute 1 billion instructions/sec and that a system call takes 1000 instructions, including the trap and
Genrish500 [490]

Answer:

System calls = 500000

Explanation:

Instructions that a computer can execute = 1 billion instructions/sec

Instructions that a system call takes including the trap and context switching = 1000 instructions

When half of the CPU time is on application, n system calls can be executed in 1 second.

Therefore we'll get an equation as following.

1000 * n = 0.5 * 1000000000

n = 0.5 * 1000000000 / 1000

n = 500000

System calls = 500000

What will be the value of ans after the following code has been executed?
Lesechka [4]

Answer:

Option B 120

Explanation:

There are three variables,<em> ans, x </em>and <em>y</em> given in the code. In beginning, the variable. <em>ans,</em> holds value of 10.  And variable <em>x</em> and <em>y</em> hold value of 65 and 55, respectively. Since the value held by x is bigger than one held by y, the if condition is met and the statement ans = x + y will run. The execution of this statement will total x with y -> 65 + 55 and the initial value of <em>ans is </em>overwritten by the addition result which is 120.
