Programs remember data in the computer's memory using variables. They access the data through program elements called comments, which provide explanations, and variables, which store and manipulate numbers and other data.
In computer programming, variables are used to store and manipulate data. They act as containers that hold values, such as numbers, strings, or other types of data. Variables can be assigned values and accessed throughout the progrt ram. Comments, on the other hand, are not program elements thaemember data but are used to provide explanations or annotations within the code. They help programmers understand the purpose or functionality of specific sections of code. By combining variables for data storage and comments for code documentation, programmers can effectively write and maintain understandable and efficient programs.

The schematic diagram below shows three machines in a production unit connected to a 240 volt supply.
The layout uses different types of wire for the main wire, wire 1, wire 2, and wire 3.
Calculate the maximum current that can flow through each type of wire. The diameter of a wire is related to the maximum amount of current it
can safely carry. Use Internet resources to find the most suitable gauge of wire for each part of the wiring in the circuit. List the highest American
Wire Gauge (AWG) number that you can use for each type of wire. (Hint: For the main wire, consider how the current through it relates to the
currents through each of the machines.)
Also, state how you can protect the wiring from damage If any of the machines exceeds its maximum power rating because of a malfunction.
Answer:
[tex]\begin{array}{ccc}Wire \ Number &Maximum\ \ Current \ (A)& AWG\\&&\\Main \ Wire&16\frac{5}{6} &9\\&&\\Wire \ 1&9\frac{1}{6} &12\\&&\\Wire \ 2&5&14\\&&\\Wire \ 3&2.5&17\end{array}[/tex]
Explanation:
The given parameters of the circuit are;
The voltage applied to the circuit = 240 volt
The types of wire in the circuit are Main wire, wire 1, wire 2, and wire 3
The maximum current that can flow through each type of wire is given by the max power of the machine powered by the wire
Power, P = Voltage, V × Current, I
∴ I = P/V
The maximum power of the machine powered by wire 1 = 2,200 W
The current flowing through wire 1, I₁ = 2,200 W/(240 V) = 55/6 A = [tex]9\dfrac{1}{6} \, A[/tex]
The maximum power of the machine powered by wire 2 = 1,200 W
The current flowing through wire 2, I₂ = 1,200 W/(240 V) = 5 A
The maximum power of the machine powered by wire 3 = 600 W
The current flowing through wire 3, I₃ = 600 W/(240 V) = 2.5 A
Therefore, Kirchhoff's current law, we have;
The current that the main wire can carry, I = I₁ + I₂ + I₃
∴ I = 55/6 A + 5 A + 2.5 A = 50/3 A = 16.[tex]\overline 6[/tex] A
The current that the main wire can carry, I = 16.[tex]\overline 6[/tex] A
The highest American Wire Gauge (AWG) that can be used for each type of wire are listed as follows;
[tex]\begin{array}{ccc}Wire \ Number &Maximum\ \ Current \ (A)& AWG\\&&\\I&16\frac{5}{6} &9\\&&\\I_1&9\frac{1}{6} &12\\&&\\I_2&5&14\\&&\\I_3&2.5&17\end{array}[/tex]
Therefore, we have;
[tex]\begin{array}{ccc}Wire \ Number &Maximum\ \ Current \ (A)& AWG\\&&\\Main \ Wire&16\frac{5}{6} &9\\&&\\Wire \ 1&9\frac{1}{6} &12\\&&\\Wire \ 2&5&14\\&&\\Wire \ 3&2.5&17\end{array}[/tex]

Explanation:
I need help writing the algorithm I know how to do the flow chart for the first one but I’m not sure if the second question is a for loop
Answer:
The algorithm is as follows:
(a) Sales and commission
1. Start
2. Input Sales
3. Commission = 0.30 * Sales
3. If sales >= 4000.00 then
3.1 Commission = 0.60 * Sales
4. End If
5. Print Commission
6. Stop
(b) Amount of Rainfall
1. Start
2. Days = 1
3. Total = 0.0
4. While Days <= 31
4.1. Input Rainfall
4.2. Total = Total + Rainfall
4.3. Days = Days + 1
4.4. End If
5. Print Total
6. Stop
See attachment for flowchart
Explanation:
(a) Sales and commission
This begins the algorithm
1. Start
This gets sales from the user
2. Input Sales
This calculates the commission based on 30% (i.e. for sales < 4000)
3. Commission = 0.30 * Sales
This checks if sales is greater than or equal to 4000
3. If sales >= 4000.00 then
This calculates the commission as 60% of Sales
3.1 Commission = 0.60 * Sales
This ends the if condition
4. End If
This prints the calculated commission
5. Print Commission
This ends the algorithm
6. Stop
(b) Amount of Rainfall
This begins the algorithm
1. Start
This initializes the number of days to 1
2. Days = 1
This initializes total rainfall to 0
3. Total = 0.0
The following while loop is repeated until day 31st
4. While Days <= 31
This gets input for Rainfall from the user
4.1. Input Rainfall
This calculates the total rainfall
4.2. Total = Total + Rainfall
This increments the number of days
4.3. Days = Days + 1
This ends the if statement
4.4. End If
This prints the total rainfall
5. Print Total
This ends the algorithm
6. Stop

Rapid Application Development (RAD)
Explanation:
Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.
RAD is an acronym for rapid application development and it is a model that is typically based on the concepts of prototyping and iterative development technique with minimal documentation or planning involved.
In the RAD model, more priority is given to the development of the software while minimal attention is given to documentation or planning. Therefore, it focuses on developing softwares within a short period of time and using prototypes (working modules) such as templates, codes, processes, tools, etc.
Basically, the RAD model comprises of five (5) phases and these includes;
I. Business modeling.
II. Data modeling.
III. Process modeling.
IV. Application generation.
V. Testing and turnover.
In conclusion, the RAD model allows software application to be delivered with a demo of the working software at every stage of development for continuous customer interaction.

Coke has experimented with different formulations of its popular Coca Cola product, including the failed New Coke iteration. The aim is to achieve the best tasting product that customers like.
A company that is operating a factory or assembly line may experiment with different methods of arranging the assembly line or with different production methods. Each time the production process is changed, this is a different iteration. Each time the order of operations and procedures are changed, this is a different iteration. The goal is to achieve the fastest, best and most optimal method of creating a product.
A musician may start with one version of a song and refine it, making changes to a note here and there or changing the tempo and speed. Many different iterations of a song may be created this way until the optimal finished product has been created that sounds and works the best.
A cook may experiment with a recipe, tweaking the ingredients or changing different steps of the process slightly until the food tastes as good as it possibly can.
Microsoft has released multiple versions of the Windows operating system to add functionality for users and to correct bugs. Each different version is a different iteration of its operating system and the goal is for the next iteration to be better than the last.

In computing flowcharts how are decisions represented?
What is the command used most for decisions?
Answer:
See Explanation
Explanation:
How decisions are represented?
In flowcharts, decisions are represented using diamond shapes (see attachment)
Decisions could be conditional statement or repetition operations which may have the form of loops or iterations.
Either of theses are represented using the diamond shapes.
Take for instance:
To check if a is greater than b... Simply write if a > b i the diamond box
Command used for most decisions
Most decisions are conditional statements; hence, the if command is often used for decisions.
