  4. Computer system • A computer system is a set of interacting or interdependent entities. • Computer systems have a structure that is defined by its parts and processes. • All computer systems function using inputs and outputs. BACK NEXT

  5. System software • System software handles technical details. • System software works with the end user, application/utility software, and computer hardware. • There are three main types of programs that make up the system software. 1. Operating system 2. Application/utility software 3. Device drivers BACK NEXT

  17. Operating system Every computer has an operating system. NEXT

  18. Operating system Operating systems provide a basis for application programs and acts as an intermediary between user and hardware. An operating system is sometimes called the software environment or platform. BACK NEXT

  19. Operating system Operating systems handles behind the scene activities that we don’t usually consider. These tasks include: 1. Loading and running programs 2. Organizing files 3. Coordinating networks that share resources BACK NEXT

  20. Categories of Operating systems - Environments Three main environments of operating systems 1. Stand-alone operating system – Desktop 2. Networked operating system – Linked computers 3. Embedded operating system – Hand-held BACK NEXT

  21. Categories of Operating systems - Divisions Two distinct divisions of operating systems 1. Proprietary - Owned and licensed by a corporation - Most operating system are proprietary 2. Non-Proprietary - Source code is free and available to the public - Called an open source program BACK NEXT

  22. Categories of Operating systems - Makes Four main makes of operating systems 1. UNIX 2. Microsoft Windows 3. Mac OS (Apple/Macintosh) 4. Linux BACK NEXT
