Suppose a program takes 1000 machine instructions to run from start to end, and can do that in 10 microseconds when no page faul

Tema [17]

Answer:

(10^6 + 9.9)

Explanation:

Given:

Total number of machine instructions = 1000

Number of page fault in 100 instructions = 1

Number of page faults in 1000 instructions = 10

Time to serve one page fault = 100 milliseconds

Time to serve ten page faults = 100*10 milliseconds = 1000 milliseconds = 10^6 Microseconds

Number of instructions without any page fault = 1000 - 10 = 990

Time required to run 1000 instructions = 10 Microseconds

So, time required to run 990 instructions = (10*(990/1000)) Microseconds = 9.9 Microseconds

So, the total time required to run the program = (10^6 + 9.9) Microseconds

The length, height, and width of a cube are 10, 7, and 5 cm respectively. Write a program that calculates the volume, perimeter,

RideAnS [48]

Answer:

// code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

int length=10,height=7,width=5;

// find the volume of

int vol=length*height*width;

// find the surface area

int sa=2*(length*width+length*height+height*width);

// find the perimeter

int peri=4*(length+width+height);

// print the volume

cout<<"Volume is: "<<vol<<" cm^3."<<endl;

// print the surface area

cout<<"Surface area is: "<<sa<<" cm^2."<<endl;

// print the perimeter

cout<<"Perimeter is: "<<peri<<" cm."<<endl;

return 0;

}

Explanation:

Declare and initialize length=10, width=5 and height=7.calculate volume by multiply length, width and height and assign to variable "vol".Then find the surface area as 2*(length*width+length*height+height*width) and assign it to variable "sa".Then find the perimeter as 4*(length+width+height) and assign to variable "peri". Print the volume, perimeter and surface area.

Output:

Volume is: 350 cm^3.

Surface area is: 310 cm^2.

Perimeter is: 88 cm.

Introduction to Computer

Computers are the machines that can perform tasks or calculations according to set of instructions or programs. The term computer is derived from the word compute which means to calculate. Computer is an electronic device that can perform arithmetic and logical calculations faster. The first fully electronic computers, introduced in 1940s, were huge machines that required teams of people to operate. Compared to those early machines, today's computers are not only thousand times faster, they can fit on your desk, lap and even pocket. You must appreciate the impact of computer in our day-to-day life. The computer has been useful in reservation of tickets in Airlines and Railways, payment of telephone and electricity bills, deposits etc.

Advantages of computer

Computers are very fast due to which thousands of job can be performed within a short period of time.

Complex mathematical problems and logical operations can be solved by using this computer.

As computer is a versatile device, multiple task like communication, graphics, documentation can be done.

A huge amount of data can be stored and retrieved as it has high storage capacity.

Disadvantages of computer

Computers are machine hence, they have no brain so they work according to the program instructions set inside it.

It is an electronic device and it uses electrical sources to work, so it is very risky to store data and information on the computer independently because some electrical and electronic damages may damage the data. So we have to make regular backup of the data.

Since computers are very expensive device, it becomes beyond the capacity of general user. But now a day its price is going down than past.

Computers require dustless and temperature maintained environment for best performance
