The three components of a CPU are:
1. Arithmetic Logic Unit (ALU)
The ALU is the part of a CPU that performs all arithmetic computations including addition, subtraction, multiplication, and division.

2. Control Unit
The CPUs control unit is responsible for executing or storing the results coming out of the ALU. Within the CPU, the control unit performs the functions of fetch, decode, execute, and store.

3. Registers
 Registers work under the direction of the control unit to accept, hold and transfer instructions or data and perform arithmetic or logical comparisons at a high rate of speed.

Explain Organizational approach to System Analysis and Design

9966 [12]

Answer:

The major goal of systems analysis and design is to improve organizational systems. Often this process involves developing or acquiring application software and training employees to use it. Application software, also called a system, is designed to support a specific organizational function or process, such as inventory management, payroll, or market analysis. The goal of application software is to turn data into information. For example, software developed for the inventory department at a bookstore may keep track of the number of books in stock of the latest best seller. Software for the payroll department may keep track of the changing pay rates of employees. A variety of off-the-shelf application software can be purchased, including WordPerfect, Excel, and PowerPoint. However, off-the-shelf software may not fit the needs of a particular organization, and so the organization must develop its own product.

Explanation:

Information systems analysis and design is a method used by companies ranging from IBM to PepsiCo to Sony to create and maintain information systems that perform basic business functions such as keeping track of customer names and addresses, processing orders, and paying employees. The main goal of systems analysis and design is to improve organizational systems, typically through applying software that can help employees accomplish key business tasks more easily and efficiently. As a systems analyst, you will be at the center of developing this software. The analysis and design of information systems are based on:

Your understanding of the organization’s objectives, structure, and processes

Your knowledge of how to exploit information technology for advantage

A function that receives a string containing a 32-bit hexadecimal integer. the function must return the decimal integer value of the hexadecimal integer.

<h3>The C++ Program</h3>

#include<iostream>

#include <cstring>

#include <string>

using namespace std;

int getDecimalForm(string);

int main() {

// string binary;

// Reads both 0 and B as int 48 while B should be

string hexadecimal = "01F12EBA";

int decimalForm;

int re = hexadecimal[0], te = hexadecimal[1];

/*cout << "Input an eight digit binary string of 1s and 0s to find the integer

value in decimal form:\n"; cin >> binary;

// Input validation

while (binary.size() != 8 || ((binary[0] != '0' && binary[0] != '1')

|| (binary[1] != '0' && binary[1] != '1') || (binary[2] != '0' && binary[2] !=

'1')

|| (binary[3] != '0' && binary[3] != '1') || (binary[4] != '0' && binary[4] !=

'1')

|| (binary[5] != '0' && binary[5] != '1') || (binary[6] != '0' && binary[6] !=

'1')

|| (binary[7] != '0' && binary[7] != '1')))

{

cout << "Input a valid eight digit binary string of only ones and zeros\n";

cin >> binary;

}*/

cout << "The 32-bit binary integer value is " << hexadecimal << endl;

cout << re << " " << te << " " << hexadecimal[0] - 55 << endl;

decimalForm = getDecimalForm(hexadecimal);

cout << endl

<< decimalForm << " is the same integer value expressed in decimal form";

}

// a function in C++ that receives a string containing a 16 - bit binary integer

int getDecimalForm(string hStr) {

int value, num = 1, total = 0, exponent = 0;

// Made adding happen starting from the right side

for (int i = (hStr.size() - 1); i >= 0; i--) {

if ('0' <= hStr[i] <= '9') {

cout << hStr[i] << " cat\n";

if (exponent != 0) {

for (int j = 0; j < exponent; j++) {

num *= 16;

}

value = num * (hStr[i] - 48);

}

if ('A' <= hStr[i] <= 'F') {

cout << hStr[i] << " dog\n";

if (exponent != 0) {

for (int j = 0; j < exponent; j++) {

num *= 16;

}

value = num * (hStr[i] - 55);

}

// Keep adding the value of the binary integer

total += value;

num = 1;

exponent++;

}

return total;
