This document discusses system software and its two main types: operating systems and utility programs. It provides examples of common operating systems like Windows, Mac OS X, and Linux. It also discusses utility programs and provides examples like file compression utilities, disk cleanup utilities, backup utilities, media players, firewalls, and antivirus software. Key factors in choosing an operating system or utility program like cost, security features, and specifications are also mentioned.

1. Consists of the programs that control or maintain the operations of the computer and its devices. Serves as the interface between the user, the application software, and the computer’s hardware. System Software

2. Operating Systems Utility Programs Two Types of System Software

3. Operating system (OS) is a set of programs containing instructions that work together to coordinate all the activities among computer hardware resources. Operating System

4. Kinds of Operating Systems

5. is a complete operating system that works on a desktop computer, notebook computer, or mobile computing device. Some are called client operating systems because they also work in conjunction with a server operating system. Stand-Alone Operating Systems

6. Windows 7 Mac OS X Linux Examples of Stand-Alone Operating Systems

7. is an operating system that is designed specifically to support a network. The client computers on the network rely on the server(s) for resources. Server Operating Systems

8. Windows Server 2008 UNIX Linux Solaris NetWare Examples of Server Operating Systems

9. The operating system on mobile devices and many consumer electronics are called embedded operating system, Embedded Operating Systems

10. Windows Mobile iPhone OS BlackBerry Google Android Symbian OS. Examples of Embedded Operating Systems

11. Is a type of system software that allows a user to perform maintenance-type tasks, usually related to managing a computer, its devices, or its programs. Utility Programs

12. Examples of Utility Programs

13. A file compression utility shrinks the size of a file(s). A compressed file takes up less storage space than the original file. File Compression Examples: WinZip WinRAR ALZip

14. Writes text, graphics, audio, video files on a recordable or rewritable CD, DVD, or Blu-ray Disc. Disc Burning

15. A disk defragmenter is a utility that reorganizes the files and unused space on a computer’s hard disk so that the operating system accesses data more quickly Disk Defragmenter

16. A disk cleanup utility searches for and removes unnecessary files. Disk Cleanup

17. A backup utility allows users to copy, or back up, selected files or an entire hard disk to another storage medium Backup and Restore Utilities

18. A media player is a program that allows you to view images and animation, listen to audio, and watch video files on your computer Media Player

19. A personal firewall is a utility that detects and protects a personal computer from unauthorized intrusions. Personal firewalls constantly monitor all transmissions to and from a computer. Personal Firewall

20. An antivirus program protects a computer against viruses by identifying and removing any computer viruses found in memory, on storage media, or on incoming files. Antivirus Program

21. Computer Performance

22. What is computer performance? Computer performance is characterized by the amount of useful work accomplished by a computer system compared to the time and resources used.

23. A good computer performance can be classified with the following:

24. Short response time for a given piece of work. High throughput (rate of processing work). Low utilization of computing resource(s)

26. Fast (or highly compact) data compression and decompression.

28. Well-Known Operating Systems Windows Mac Linux

29. Specifications to Look at when Buying O.S Design Cost Speed Applications Security Features Maintenance Ease of Use

36. Artist

37. Programmer

38. Noob

41. Well-Known Mobile Operating Systems Windows (HTC Arrive) Iphone OS (Iphone 4) Google Android (Dell Streak) Blackberry (Torch) Symbian OS (N8)

42. Mobile O.S we recommend is either Apple, or Google Android. Android knows better than any other OS how to manage Google maps, Gmail, Geolocators, browsers, and a lot of other Google applications. Many people might disagree and will consider Blackberry or Android as better, but once you use its full capacity then you realize what's the Magic of Apple.
