<u>Paired programming:</u>

Paired programming is a new technique where one person gets one another to<em> write the code</em>. Here one will write the code and other will start verifying as the type.

So we might think it is waste to employ two person for same task but it is not so. There are many <em>benefits in incorporating this technique</em>. Let us see those benefits one by one.

  • <em>Inter-personal skill gets improved </em>
  • <em>Lower amount of coding mistake </em>
  • <em>Learn from each other </em>
  • <em>Peer review enhance collaboration </em>

Challenges expect to arise during pair-programming

  • Two heads are superior to one. On the off chance that the driver experiences a <em>hitch with the code</em>, there will be two of them who'll take care of the issue.  
  • Builds up your <em>staff's relational aptitudes</em>. Working together on a solitary venture encourages your group to welcome the estimation of <em>correspondence and collaboration.  </em>

Overcome Method

The most ideal approach to move <em>toward blending</em> is to accomplice two software engineers and have them share a PC. The pair ought to have the option to choose how to part the work, and it is prudent that they should <em>switch jobs frequently.</em>

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

a)

n= Input “Enter 5 integer value”

b)

sum=0.0

For loop with i ranging from 0 - 5

Inside loop sum=n[i]+sum

Outside loop avg= sum/5

Print avg

c)

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

d)

print avg

print small

print large
