Answer: B. PDF

Explanation:

Portable Document Format (PDF) is such an important document that it is considered the international standard for information and document exchange. It is used for letters, resumes and even electronic contracts.

PDF was developed by Adobe to make it independent of the device or application it is being viewed on and combines layers of information into one layer thereby making it a flat document.

Suppose your company has decided that it needs to make certain busy servers faster. Processes in the workload spend 60% of their

vekshin1

Answer:

CPU need 50% much faster

disk need 100% much faster

Explanation:

given data

workload spend time CPU = 60%

workload spend time I/O = 40%

achieve overall system speedup = 25%

to find out

How much faster does CPU need and How much faster does the disk need

solution

we apply here Amdahl’s law for the overall speed of a computer that is express as

S = $\frac{1}{(1-f)+ \frac{f}{k} }$ .............................1

here f is fraction of work i.e 0.6 and S is overall speed i.e 100% + 25% = 125 % and k is speed up of component

so put all value in equation 1 we get

S = $\frac{1}{(1-f)+ \frac{f}{k} }$

1.25 = $\frac{1}{(1-0.6)+ \frac{0.6}{k} }$

solve we get

k = 1.5

so we can say CPU need 50% much faster

and

when f = 0.4 and S = 125 %

put the value in equation 1

S = $\frac{1}{(1-f)+ \frac{f}{k} }$

1.25 = $\frac{1}{(1-0.4)+ \frac{0.4}{k} }$

solve we get

k = 2

so here disk need 100% much faster

What will be the values of ans, x, and y after the following statements are executed? int ans = 35, x = 50, y =50; if ( x >=

Nutka1998 [239]

Answer:

B. ans = 60; x = 0; y = 50

Explanation:

(i)First format the code properly as follows:

int ans = 35, x = 50, y =50;

if ( x >= y) {

ans = x + 10;

x -=y;

} else {

ans = y + 10;

y += x;

}

(ii) Taking the if statement of the code;

The if statement block is executed if x is greater than or equal to y (x >= y).

Since x=50 and y=50, then the code continues to execute the statement in the block.

In the if block;

(a) the first line is

ans = x + 10.

Since x = 50, substituting for x gives

ans = 50 + 10 = 60

Therefore ans = 60

(b) the second line is

x -= y

This can be re-written as

x = x - y.

This means that the value of x - y is written back into x. Therefore since x = 50 and y = 50, substituting for x and y gives

x = 50 - 50 = 0

Therefore x = 0

(iii) Taking the else statement of the code;

Since the if statement of the code has been executed, the else statement is simply skipped.

Therefore the final values of ans, x, y are respectively 60, 0 and 50
