D278 Scripting and Programming Foundations - Set 1 - Part 1

Correct Answer: Input, process, output

A computer program typically involves three basic instructions: input, process, and output. The input gathers data, processing manipulates it, and output delivers the result.

Correct Answer: A reference to data whose value can change during program execution

A variable refers to data that programs use, and its value can change as the program runs, hence the name "variable."

Correct Answer: Base x Height / 2

The area of a triangle is calculated by multiplying its base by its height, then dividing by 2.

Correct Answer: Sum the numbers and divide by the total number of values

The average is found by adding all the numbers together and then dividing by the number of values in the set.

Correct Answer: Creating a sequence of instructions to solve a problem

Computational thinking involves formulating problems and their solutions in a way that a computer can execute the steps efficiently.

Correct Answer: A sequence of instructions that solves a problem

An algorithm is a step-by-step sequence of instructions designed to perform a specific task or solve a particular problem.

Correct Answer: A graphical language for creating programs

A flowchart is a diagram that represents a process, showing the steps using various shapes and arrows to demonstrate the flow of control.

Correct Answer: A list of statements that execute one at a time

A program is a collection of instructions or statements executed by the computer to perform a specific task.

Correct Answer: Interpreter

An interpreter executes program instructions one at a time, as opposed to a compiler, which translates the entire program before execution.

Correct Answer: Statement

A statement is an instruction in a program that performs a specific action, such as assigning a value to a variable or calling a function.

Correct Answer: Parallelogram

In a flowchart, a parallelogram is used to represent input or output operations.

Correct Answer: \n

The escape sequence "\n" is used in programming languages to create a new line in the output.

Correct Answer: Text added by the programmer for human understanding

Comments are added to code for clarity and are ignored by the program during execution. They help others understand the code better.

Correct Answer: Variable names and digits of a number

Variable names and digits in numbers should not include any whitespace, as this would create a syntax error in most programming languages.

Correct Answer: Late 1700s

The industrial age began in the late 1700s with the advent of machinery and manufacturing processes.

Correct Answer: 1990s

The information age, marked by the rise of the internet and computer technology, began in the 1990s.

Correct Answer: A computer inside another device

Embedded computers are found within other devices, such as cars, TVs, and home appliances, performing dedicated functions.

Correct Answer: A letter, symbol, or digit

A character represents a single letter, number, or symbol in text-based data.

Correct Answer: American Standard Code for Information Interchange, 1963

ASCII is a character encoding standard developed in 1963 to represent text in computers and communication devices.

Correct Answer: 7 bits

ASCII uses 7 bits to represent characters, allowing for 128 possible characters.
