CompTIA Tech+ - Domain 4

Interpreted Language

Code executed line-by-line at runtime by an interpreter

examples include Python and JavaScript.

Scripting Language

Lightweight interpreted languages used for automation, small programs, or web scripting (e.g., Bash, JavaScript).

Markup Language

Language using tags to structure content such as HTML or XML.

Compiled Language

Code translated into machine language before execution for faster performance (e.g., C++, Rust).

Query Language

Used to retrieve/manipulate data from databases (SQL).

Assembly Language

Low-level language close to machine code, used for hardware-level programming.

Char (character) Data Type

Single letter or symbol stored as text.

String Data Type

Sequence of characters used to represent text.

Integer Data Type

Whole numbers with no decimal points.

Float Data Type

Number with decimal values.

Boolean Data Type

Logical value representing true or false.

Identifier

A name used to label programming elements like variables or functions.

Variable

Named storage location that can change value during program execution.

Constant

Fixed value that cannot change while the program runs.

Array

Data structure holding multiple values under one name, accessed by index.

Function

Reusable block of code designed to perform a specific task.

Object

Structure combining data (properties/attributes) and behaviors (methods).

ex: car

Object Properties

Characteristics or data stored inside an object.

ex: color, interior, mileage

Object Attributes

Additional details describing object data.

ex: make, model, year

Object Methods

Functions contained inside an object.

ex: car can start, stop, accelerate, brake

Pseudocode

Human-readable outline of program logic used before actual coding.

Object-Oriented Methods

Programming approach using objects, classes, and inheritance.

Flowchart

Diagram showing logical flow of a program or process.

Sequence

Step-by-step execution order in programming logic.

Branching

Decision-making using IF/ELSE based on conditions.

Looping

Repeated execution of code until a condition is met.

For Loop

Loops that have a predetermined beginning, end, and increment (step interval).

While loop

A loop that continues to repeat while a condition is true.
