A precise sequence of instructions for processes that can be executed by a computer
AND operation
Boolean operation: only evaluates to true when both of the operands are true
Boolean
A single value of either TRUE or FALSE.
Boolean Expression
In programming, an expression that evaluates to True or False
Bug
Part of a program that does not work correctly.
Conditional
Statement that only runs under certain conditions.
Decomposition
Breaking a larger problem down into smaller parts
Equality operator
Comparison/logical operator: evaluates to true when the operands have the same value.
Expression
Any valid unit of code that resolves to a value.
Function
A named group of programming instructions. Functions are reusable abstractions that reduce the complexity of writing and maintaining programs.A named group of programming instructions. Functions are reusable abstractions that reduce the complexity of writing and maintaining programs.
Greater than operator
Comparison/logical operator: evaluates to true when the left operand has a value more than the right operand.
Greater than or equal operator
Comparison/logical operator: evaluates to true when the left operand's value is at least as great as the right operand's.
If-Else
Sets up two code pathways: one when a condition is met, another when the condition is not met
If-Statement
The common programming structure that implements "conditional statements".
Inequality operator
Comparison/logical operator: evaluates to true when the two operands have different values.
Less than operator
Comparison/logical operator: evaluates to true when the left operand's value is lower than the right operand's value.
Less than or equal operator
Comparison/logical operator: evaluates to true when the right operand's value is at least as great as the left operand's value.
Logical operator
Type of operator that evaluates one or more values and returns a boolean result of true or false
Modulo
A mathematical operation that returns the remainder after integer division. Example: 7 MOD 4 = 3
NOT operation
Boolean operation: flips the truth value of its operand
OR operation
Boolean operation: only evaluates to false when both operands are false; true otherwise
Parameter
An extra piece of information passed to a function to customize it for a specific need.
Phishing
tricking people into giving up secure information
Program
An algorithm that has been coded into something that can be run by a machine.
Program statement
A part of a program that executes a single action
Ransomware attack
An attack type that encrypts files on a computer and asks the users for money before decrypting files
Statement block
A set of program statements that execute one after the other
Statement terminator
A special character indicating the end of a program statement
String data type
In most languages. can store sequences of characters.
Syntax
The vocabulary and grammar of a language, programming or otherwise
Syntax error
A problem with the vocabulary or grammar of a program
Variable
A placeholder for a piece of information that can change.
