Study Notes

Operating System

  • An operating system (OS) is software that manages computer hardware and software resources, providing common services to computer programs.
  • It is the fundamental program of a computer.
  • Software is a set of instructions and procedure provided to the computer for performing activities or tasks. It's like the blood that flows through the system.

Types of Operating Systems

  • Single-user operating system: Supports only one user at a time. Can be further divided into:
    • Single user, single task: Allows only one task at a time (e.g., Palm OS, MS-DOS).
    • Single user, multi-tasking: Allows multiple programs to run at the same time (e.g., Windows).
  • Multi-user operating system: Allows multiple users to use the computer's resources at the same time. This includes time-sharing systems and internet servers.

Examples of Operating Systems

  • MS-DOS
  • Windows
  • Linux (with GUI or command-line interface, and network capabilities)
  • Xenix (Unix-based, multi-user)
  • Unix
  • MacOS
  • Novell NetWare (network-oriented command-line OS)

Functions of an Operating System

  • Resource Management: Manages hardware and software resources of the system.
  • Storage Management: Controls all storage operations, and device allocation.
  • Process Management: Ensures that active processes have fair and non-interfering access to the central processing unit (CPU).
  • Security Management: Protects the computer from unauthorized or malicious interventions.
