What kind of device is a cpu input or output?

1 answer:

3 0

Correct answer: Neither

The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program. This program will take inputs from an input device, process the input in some way and output the results to an output device. It is neither an input nor an output device, but it is usually connected to both kinds of devices.

Output devices like your monitor, speaker, and printer does not process anything fo it to be categorized as a processing device like your CPU and so as input devices like your mouse, microphone, and keyboard.

Programming challenge description: Write a program that, given two binary numbers represented as strings, prints their sum in bi

Lubov Fominskaja [6]

Answer:

The program to this question can be given as:

Program:

#include<iostream> //include header file

using namespace std;

string add(string a, string b) //define add function

{ //declare variable

string result = "";

int sum = 0,k,l;

cahr x;

k= a.size() - 1;

l = b.size() - 1;

while (k>= 0 || l>= 0 || sum == 1) //loop

{

//addition

sum= sum+ ((k >= 0)? a[k] - '0': 0);

sum= sum+ ((l >= 0)? b[l] - '0': 0);

x=sum%2;

result=(x+'0') +result;

// Compute carry

sum =sum/ 2;

// Move to next digits

k--;

l--;

}

return result; //return value

}

int main() //main method

{

string a,b; //string variable

cout<<"Enter first binary digit: "; //message.

cin>>a; //input from user

cout<<"Enter Second binary digit: "; //message.

cin>>b; //input from user

cout <<"Addition :"<<add(a, b)<<endl; //print addition

return 0;

}

Output:

Enter first binary digit: 1101

Enter Second binary digit: 100

Addition :10001

Explanation:

In the above c++ program first, we include the header file. Then we define the add function in the add function we add two binary digits by passing value as arguments. In this function, we define a variable that is used on the addition of binary numbers. In this function we define the loop in the loop we check if two binary number is 1 then it will print 0 and pass 1 as the carry. after performing addition it will return value. In the main function, we take two binary numbers from the user and pass the value to the function and print function return value.

V125BC [204]

Answer: Operate over existing telephone lines to carry voice, data, and video.

Explanation:

Digital subscriber line is a means of transferring high bandwidth data over a telephone line. Such data could be a voice call, graphics or video conferencing. DSL uses a user's existing land lines in a subscriber's home, allowing users to talk on a telephone line while also being connected to the Internet. In most cases, the DSL speed is a function of the distance between a user and a central station. The closer the station, the better its connectivity.

Illustrate that the system is in a safe state by demonstrating an order in which the threads may complete.If a request from thre

Kamila [148]

Answer:

a. safe sequence is T2 , T3, T0, T1, T4.

b. As request(T4) = Available, so the request can be granted immediately

c. As request(T2) < Available, so the request can be granted immediately

d. As request(T3) < Available, so the request can be granted immediately.

Explanation:

It will require matrix

[i, j] = Max [i, j] – Allocation [i, j]

A B C D

T0 3 3 3 2

T1 2 1 3 0

T2 0 1 2 0

T3 2 2 2 2

T4 3 4 5 4

Available = (2 2 2 4)

1. Need(T2) < Available so, T2 can take all resources

Available = (2 2 2 4) + (2 4 1 3) (Allocation of T2) = (4 6 3 7)

2. Need(T3)<Available so, T3 will go next

Available = (4 6 3 7) + (4 1 1 0) = (8 7 4 7)

Like wise next T0, T1, T4 will get resources.

So safe sequence is T2 , T3, T0, T1, T4.

(Note, there may be more than one safe sequence).

Solution b.

Request from T4 is (2 2 2 4) and Available is (2 2 2 4)

As request(T4) = Available, so the request can be granted immediately.

Solution c.

Request from T2 is (0 1 1 0) and Available is (2 2 2 4)

As request(T2) < Available, so the request can be granted immediately.

Solution d.

Request from T3 is (2 2 1 2) and Available is (2 2 2 4)

As request(T3) < Available, so the request can be granted immediately.
