This module provides an introduction to operating system design, implementation, operation and administration. The module examines the major components of operating systems and their relationship with hardware and software layers. The module equips the learner with the ability to upkeep and configure a reliable operation of computer systems.

Objectives

This module will ensure learners meet the following objectives:

  1. Understand the theoretical and practical aspects of modern operating systems.
  2. Evaluate different operating-systems architectures and their advantages.
  3. Identify common file systems, device and process management practices.
  4. Maintain industry-standard operating systems via command line and graphical user interfaces.

Operating System Basics

  • The development of operating systems
  • Timeline for the development of Microsoft Windows operating system
  • Timeline for the development of Linux, and Mac OS operating systems
  • Overview of the tasks that an operating must perform
