Computing Fundamentals Lesson One

What is a program?

A program is a set of instructions executed sequentially to perform specific tasks.

What is the purpose of input in a program?

Input serves as the foundation for processing within the program, received from sources like files or keyboards.

What does the process stage of a program involve?

The process stage involves performing computations on the input data to transform it into meaningful results.

What is output in the context of programming?

Output is the result generated after processing, which can be displayed, saved, or sent to another program.

What are variables in programming?

Variables are symbolic names that hold data values and are essential for storing and manipulating data.

Define an algorithm.

An algorithm is a defined sequence of steps designed to solve a specific problem.

What is the role of a flowchart in programming?

A flowchart visually represents a program's logic and flow, using symbols for different types of actions.

What is an interpreter?

An interpreter is a program that executes statements of another program line by line for immediate execution.

How do you retrieve user input in programming?

User input is retrieved using a statement like 'variable = Get next input'.

What is a string literal?

A string literal is a sequence of characters enclosed in double quotes representing fixed text.

What does a comment do in programming?

Comments are annotations ignored during execution that help programmers understand the logic and purpose of the code.

What is a bit?

A bit is the smallest unit of data in computing, represented as either a 0 or a 1.

What constitutes a byte?

A byte consists of 8 bits.

What is character encoding?

Character encoding assigns a unique bit code to each character, with ASCII being a common standard.

Define pseudocode.

Pseudocode is a simplified, human-readable outline of a program's logic without strict syntax rules.

How do you format output to move to the next line?

Using '
' at the end of a string moves the cursor to the next line.
