Study Notes

Primary Function of an Operating System

  • Manages hardware resources and provides a user interface.
  • Facilitates communication between software and hardware.

Examples of Operating Systems

  • Microsoft Windows
  • macOS
  • Linux
  • UNIX

User Needs Addressed by an Operating System

  • Provides a platform for running applications.
  • Manages files, memory, and processes for user convenience.

Character User Interface (CUI)

  • Requires users to recall commands for operation.
  • Common examples include command-line interfaces (CLI).

Consequences of No Operating System

  • A computer would be unusable as it would lack resource management and user interface access.

Graphical User Interface (GUI) Components

  • Windows
  • Icons
  • Menus
  • Pointing Devices

Multiprogramming Operating System

  • Supports multiple users accessing the system simultaneously from different terminals.
  • Enhances resource utilization and efficiency.

Main Purpose of Batch Operating System

  • Executes large jobs without user interaction, optimizing processing time.

Disadvantages of Batch Operating System

  • Time-consuming setup for jobs.
  • Lack of interaction may lead to inefficient error handling.

Interaction Types

  • Direct Interaction: Users engage with the system actively via GUI.
  • Two-Way Communication: Characterized by interactive systems allowing user feedback.

Components of a Multiprogramming Operating System

  • Process management
  • Memory management
  • I/O management

Early Single User Systems Storage

  • Programs were typically stored on magnetic tape or magnetic disks in the 1950s.

Suitable Operating Systems for Large Jobs

  • Batch operating systems are ideal for tasks requiring no user interaction for output generation.
