Answer:

Modulus operator are useful in many circumstances and it is commonly used to generate the random number. It basically reduce the number into random number in a small range.

It also describe that whether, the one number is a factor of another or not.

In C language, the modulus operator provide the remainder after diving the greater value with the smaller value. If the smaller number are divided by the larger number then, the quotient become zero.

Please list the computer data hierarchy from bit to database

vladimir2022 [97]

Answer:

Data hierarchy is basically define to the data which is organized in the systematic manner. The main concept of the data hierarchy is to check the basic structure of the data. It basically involve the fields records and files for the data organization.

The following is the list of the computer data hierarchy from nit to address are:

1) Bit: It is the smallest unit of the data.

2) Field: The collection of all the characters in the data is known as field.

3) Record: The collection of the different fields is known as records.

4) File: The collection of various types of records in the database is known as file.

Answer:

#include <iostream>

using namespace std;

int main()

{

char address[2];

int tag, firstBit, secondBit, setNumber;

int cache[4][2]={{1,5}, {2,4}, {3,2}, {6,0}};

cout << "Enter the address as hex(in small letters: "<

cin >> address;

for (int i < 0; i < 8; i++){

if (address[0] == '0'){

tag = 0;

firstBit = 0;

} else if (address[0] == '1'){

tag = 0;

firstBit = 1;

} else if (address[0] == '2'){

tag =1;

firstBit = 0;

} else if (address[0] == '3'){

tag = 1;

firstBit = 1;

} else if (address[0] == '4'){

tag = 2;

firstBit = 0;

} else if (address[0] == '5'){

tag = 2;

firstBit = 1;

} else if (address[0] == '6'){

tag = 3;

firstBit = 0;

} else if (address[0] == '7'){

tag = 3;

firstBit = 1;

} else if (address[0] == '8'){

tag = 4;

firstBit = 0;

} else if (address[0] == '9'){

tag = 4;

firstBit = 1;

} else if (address[0] == 'A'){

tag = 5;

firstBit = 0;

} else if (address[0] == 'B'){

tag = 5;

firstBit = 1;

} else if (address[0] == 'C'){

tag = 6;

firstBit = 0;

} else if (address[0] == 'D'){

tag = 6;

firstBit = 1;

} else if (address[0] == 'E'){

tag = 7;

firstBit = 0;

} else if (address[0] == 'F'){

tag = 7;

firstBit = 1;

} else{

cout<<"The Hex number is not valid"<< endl;

}

if(address[1]>='0' && address[1]<'8'){

secondBit = 0;

} else if(address[1]=='8'|| address[1]=='9'||(address[1]>='a' && address[1]<='f')){

secondBit = 1;

} else{

cout<<"The Hex number is not valid"<< endl;

return 0;

}

setNumber = firstBit * 2 + secondBit;

if(cache[setNumber][0]==tag || cache[setNumber][1]==tag){

cout<<"There is a hit";

} else{

cout<< "There is a miss";

}

return 0;

}

Explanation:

The C++ source code prompts the user for an input for the address variable, then the nested if statement is used to assign the value of the firstBit value given the value in the first index in the address character array. Another if statement is used to assign the value for the secondBit and then the setNumber is calculated.

If the setNumber is equal to the tag bit, Then the hit message is printed but a miss message is printed if not.

Low Vision Aid for Computer Users

Explanation:

Visually impaired people can use the same low vision aids for viewing a computer screen as they do for regular reading activities. These include eyeglass-mounted magnifiers, handheld magnifiers and stand-alone magnifiers. But also, special software has been developed to display content on the screens of computers and other digital devices in large print. Other applications can read text and other visual content aloud with a synthetic voice. These adaptive low vision devices let partially sighted people do the same computer-related tasks as fully sighted people — such as word processing, creating and using spreadsheets and viewing web pages online.
