Answer:

I will code in Javascript.

Preconditions:

  • The variable dollar is passed by parameter to the function.

function Dollars(dollar) {

 

//declare and initialize the variables.

 var twenties = 0;

 var tens = 0;

 var fives = 0;

 var ones = 0;

 

<em>//If dollar is greater or equals 20, divide dollar by 20 and save it into the variable twenties. Then, save the remainder into the variable dollar.  </em>

 if(dollar >= 20){

   twenties = Math.floor(dollar/20);

   dollar = dollar % 20;

 }

<em>//If dollar is greater or equal 10, divide dollar by 10 and save it into the variable twenties. Then, save the remainder into the variable dollar.  </em>

 if(dollar>=10){

   tens = Math.floor(dollar/10);

   dollar = dollar % 10;

 }

<em>//If dollar is greater or equal 5, divide dollar by 5 and save it into the variable twenties. Then, save the remainder into the variable dollar.  </em>

 if(dollar>=5){

   fives = Math.floor(dollar/5);

   dollar = dollar % 5;

 }

<em> //If dollar is greater or equal 1, divide dollar by 1 and save it into the variable twenties. Then, save the remainder into the variable dollar.   </em>

 if(dollar>=1){

   ones = Math.floor(dollar/1);

   dollar = dollar % 1;

 }

//At this point, dollar is equal 0.It's time to display the conversion.

Console.log('20s :' + twenties);

Console.log('10s :' + tens);

Console.log('5s :' + fives);

Console.log('1s :' + ones);

}

Explanation:

The variable Math.floor(num) is used to round a number downward to its nearest integer.

For example, if dollar=57:

twenties = dollar/20 will be 57/20 = 2

dollar = dollar % 20 will be 57 % 20 = 17

tens = dollar/10 will be 17/10 = 1

dollar = dollar % 10 will be 17 % 10 = 7

fives = dollar/5 will be 7/5 = 1

dollar = dollar % 5 will be 7 % 5 = 2

ones = dollar/1 will be 2/1 = 2

dollar = dollar % 1 will be 0 % 5 = 0

During which phase of system development would you acquire any necessary hardware and software?
solmaris [256]

During the <u>design</u> phase of system development, you would acquire all the necessary hardware and software.

<h3>What is SDLC?</h3>

SDLC is an abbreviation for system development life cycle and it can be defined as a strategic methodology that defines the key steps, phases, or stages for the design, development and implementation of high quality systems.

In Computer technology, there are seven (7) phases involved in the development of a system and these include the following;

  • Planning
  • Analysis
  • Design
  • Development (coding)
  • Testing
  • Deployment
  • Maintenance

Also, phased implementation simply refers to an implementation methodology in which smaller portions of functionality of a system are typically implemented one at a time (one after the other).

In conclusion, we can infer and logically deduce that you would acquire all the necessary hardware and software during the <u>design</u> phase of system development.

The a0 is the part of the central processing unit that performs arithmetic calculations for the computer.
Serga [27]

Answer:

It is the ALU or the Arithmetic Logic Unit.

Explanation:

It is the ALU. However, keep in mind that registers and buses do a very important task. The number of registers we have, faster is the processing, and the opposite is true as well. And there is a reason behind this if we have different channels for sending and receiving the data from the memory, and several registers for storing the data, and we can formulate the requirement seeing the requirements for full adder and half adders. Remember we need to store several variables in case of the full adder, and which is the carry, and if we have separate registers for each of them, our task becomes easier. Remember its the CU that tells the ALU what operation is required to be performed. Also remember we have the same channel for input and output in the case of Van Neumann architecture, as we have a single bus. and we also have a single shared memory. And Harvard architecture is an advanced version of it.
