Study Notes
Compiler
- Translates high-level language programs into separate machine language programs for later execution.
Interpreter
- Translates and executes high-level language instructions by converting them to machine language in real-time.
Keywords
- Reserved words in a programming language that cannot be used as variable names.
Operators
- Symbols that perform operations on data, including addition (+), subtraction (-), greater than (>), and less than (<).
Syntax
- A strict set of rules governing the structure of code, such as the use of quotation marks to denote statements.
Statements
- Individual instructions written in high-level programming languages to perform tasks.
255 bits
- Maximum value for a byte, which consists of combinations of 0s and 1s.
R.A.M
- Primary storage used for data processing; it temporarily holds data that the CPU accesses.
Disk drives, solid state drives
- Types of secondary storage devices used for data retention and retrieval over the long term.
Magnetically
- Method used for storing information on a disk drive.
Laser burning
- Technique for encoding data onto CDs and DVDs.
Digital data
- Information represented in binary format, consisting of 0s and 1s.
Digital device
- Equipment that operates using binary data, facilitating computing tasks.
Logic error
- An error that allows a program to run but results in incorrect output.
Syntax error
- A coding mistake that prevents a program from executing past the point of error.
Five steps
- The number of stages involved in the program development cycle.
Basic order of operations
- Multiplication and division take precedence over addition and subtraction during calculations.
Initial variable
- A type of variable recognized only within its module; can change throughout the program.
Constant variable
- A variable whose value remains unchanged throughout the program's execution.
Global variable
- A variable accessible from any part of the program, which can complicate programming logic.
Quotation marks
- Required punctuation used to surround strings in programming for interpretation as textual data.
String
- A data type comprised of a sequence of characters.
String literal
- A specific instance of a string represented directly in the program's source code.
Design process steps
- Understanding the task to be performed and determining the necessary steps to complete that task.
Hierarchy chart
- A visual representation showing the relationship between different modules in a program.
Argument
- A data piece passed from one module to another when calling a function or procedure.
Parameter
- A special type of variable that receives values (arguments) when a module is invoked.
Synonyms for modules
- Terms like procedures, functions, methods, and subroutines refer to code organization units.
Running a module
- A module must be called explicitly for it to execute and perform its designated tasks.
