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.
