This document provides an overview of operating systems, computer basics, file management, and networks. It defines what an operating system is and lists some common examples like Windows, MacOS, Linux, and Unix. It also explains key concepts related to operating systems like graphical user interfaces, multi-user systems, multiprocessing, multitasking, and multithreading. The document then covers basic computer hardware, software, and peripherals. It concludes with definitions and explanations of file management systems, local area networks (LANs), and wide area networks (WANs).

6. Types of Operating Systems This list represents some of the more common operating systems. This list can be separated into categories based on their design. Some OS can be placed in more than one category. Linux / Variants MacOSMS-DOS IBM OS/2 Warp Unix / Variants Windows CE Windows 3.x Windows 95 Windows 98 Windows 98 SE Windows ME Windows NT Windows 2000 Windows XP Windows Vista Windows 7

7. Graphic User Interface (GUI) This OS commonly uses a mouse for navigation and uses windows, icons and menus to carry out commands. It was developed in 1981 by Alan Kay and Douglas Engelbart, researchers working at Xerox PARC. Alan Kay Common GUI Operating Systems Microsoft Windows Apple System 7 Apple Mac OS. Douglas Engelbart

8. Multi-User A multi-user operating system allows for multiple users at once or at different times. Common Multi-User Operating Systems Linux Unix Windows

9. Multiprocessing This operating system is able to support and utilize more than one computer processor. Common Multiprocessing Operating Systems Linux Unix Windows

10. Multitasking Multitasking is the ability to run several software programs simultaneously. Common Multitasking Operating Systems Unix Windows Link to YouTube

11. Mutithreading This operating system allows different parts of a software program to run concurrently Common Multithreading Operating Systems Linux Unix Windows Link to YouTube

12. Computer Basics Computers are more than just operating systems. Computers need hardware, software and peripherals to operate properly.

13. Computer Hardware Hardware of a modern Personal Computer. 1. Monitor 2. Motherboard 3. CPU 4. RAM 5. Expansion cards 6. Power supply 7. Optical disc drive 8. Hard disk drive 9. Keyboard 10. Mouse

14. Computer Software Software programs contain data that provide directions for your computer. Software tells your computer how to act.

21. Infrastructure

22. Networking ElectronicsComputer networks come in all sizes and are commonly referred to as LAN and WAN.

23. Clients The term clients in a computer network refers to the user workstations and the peripherals

24. Infrastructure This term refers to the fiber optics and wires that all of the data being transmitted travels through.

26. Audio Video Devices
