Hardware: The physical components of a computer system, including both external (peripheral) and internal (processing and storage) parts.
Software: Any program or collection of instructions and data that can be run and processed by a computer system.
Application Software: A program that can be run on a computer, allowing the user to carry out specific tasks.
System Software: A program designed to cover technical aspects of setting up, running and maintaining a computer system, and providing a platform for application software.
Assemblers: A translator in low level language, which converts assembly language into machine code.
Compilers: A translator that converts high level language to machine code
Libraries: A collection of programs which are already compiled and can be loaded into a program and run whenever required
Operating System: A set of programs managing the operation of the computer that is loaded into RAM everytime the computer is turned on. It bridges the user to the hardware.
Translator: A program which converts code from one computer language to another
Resource Management: The collective efficient management of the available hardware and software to optimise the performance of the computer system
Scheduling: Allocating processor time to each application to ensure processor time is used as efficiently as possible when multitasking.
Assembly Language: A low-level programming language consisting of a set of mnemonic instructions that directly corresponds to the processor architecture’s machine code instruction set.
High-Level Language: A programming language with a strong abstraction from a processor’s internal instruction set that is much more human-readable with natural-language keywords, such as Python or Java
Imperative Languages: A programming language built on the programming paradigm of using subroutines and procedures as instructions to change a program’s state and describe how a program operates.
Low-Level Language: A programming language with little to no abstraction from a processor’s internal instruction set, such as machine code or assembly language.
Machine Code: A low-level programming language written in binary that is directly understood by the CPU
Boolean Expressions: A combination of boolean variables and logical operators which evaluates to either TRUE or FALSE depending on the input.
Boolean Logic: A type of algebra with logical operators where all values and expressions ultimately reduce to TRUE or FALSE.
