I don't see why this is on a computer section but either way I would chose D because naturally when you park on a hill you would be cautious about your car going into motion down the hill so therefore you would think of which way gravity would pull your vehicle

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

6. Write pseudo code that will perform the following. a) Read in 5 separate numbers. b) Calculate the average of the five number

Alex

Answer:

Pseudo CODE

n= Input “Enter 5 integer value”

sum=0.0

For loop with i ranging from 0 - 5

Inside loop sum=n[i]+sum

Outside loop avg= sum/5

Print avg

small=n[0] # assume the first number in the list is smallest

large= n[0] # assume the first number in the list is largest

For loop with i ranging from 0 - 5

Inside loop if n[i]<small #if any another number is smaller than small(variable)

Inside if Then small=n[i]

Inside loop if n[i]>large # if any another number is larger than large(variable)

Inside if then large=n[i]

Print small

Print large

print avg

print small

print large
