Operating Systems An operating system (OS) is the software program that is installed in computers, cell phones, game consoles and web servers. The OS manages the hardware of the computer and allows the computer to act in predictable ways.
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
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
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
Multiprocessing This operating system is able to support and utilize more than one computer processor. Common Multiprocessing Operating Systems Linux Unix Windows
Multitasking Multitasking is the ability to run several software programs simultaneously. Common Multitasking Operating Systems Unix Windows Link to YouTube
Mutithreading This operating system allows different parts of a software program to run concurrently Common Multithreading Operating Systems Linux Unix Windows Link to YouTube
Computer Basics Computers are more than just operating systems. Computers need hardware, software and peripherals to operate properly.
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
Computer Software Software programs contain data that provide directions for your computer. Software tells your computer how to act.
Computer Peripherals Computer peripherals are devices attached to a computer but are not part of it. Examples of Peripherals:
File Management System The internet is an endless flow of information. There is a constant inflow and outflow of data. It is important to stay organized to stay productive. Microsoft offers five tips for effective file management: Organize folders Clean up your hard disk Use System Restore Keep Windows and Microsoft Office up to date. Run antivirus software.
Networks A computer network consists of three parts:
Computer networks come in all sizes and are commonly referred to as LAN and WAN.
Clients The term clients in a computer network refers to the user workstations and the peripherals
Infrastructure This term refers to the fiber optics and wires that all of the data being transmitted travels through.
Networking Electronics This includes:
Fiber Optic Media Converters
Audio Video Devices
Local Area Network (LAN) In a LAN, clients share the same infrastructure. They are typically located in the same building or group of buildings.
Wide Area Network (WAN) A WAN usually consists of two or more LAN’s and covers a larger geographic area.
