Study Notes

What is System Programming?

System programming consists of various programs that support computer operations, enabling users to focus on applications or problem-solving.

Components of System Programming

Components of system programming include:
- Assembler
- Loader
- Compiler
- Macros
- Formal System

Assembler

An assembler is a type of computer program that interprets assembly language into machine language code and instructions executable by a computer.
Enables software and application developers to access, operate, and manage a computer's hardware architecture and components.
Sometimes referred to as the compiler of assembly language.
Provides the services of an interpreter.

Loader

A loader is a program used by an operating system to load programs from secondary to main memory for execution.

Compiler

A compiler is a computer program (or set of programs) that transforms source code written in a programming language into another language.
