Categories of Computer Software Computer Software Application SystemSoftwareSoftware 5. Define of Terms 6. Systems Software:Programs that coordinate theactivities and functions of thehardware and various otherprograms. Application Software:Programs that help users solveparticular computing problems. 7. System Software 8. System software works with end users,application software and computer hardwareto handle the majority of technical detailslike: where a program is stored; how commands are converted to getprocessed; where a document or file is saved; how output is printed. 9. Types of System Software SystemSoftwareOperatingDeviceUtilitiesBIOS Systems Drivers 10. Operating Systems (OS)An operating system is a collection of programsthat manage computer resources (memory,processing, storage, input & output devices),provides a user interface, and runs applications.The OS also monitors system performance,schedules jobs, and provides some security forthe computer. 11. Features of OS Booting: starting or restarting a computer Warm boot: when the computer is already onrestart without turning off the power Cold boot: start after power has been off. Desktop: the place to access computerresources Files: used to store data and programs Folders: related files are stored in folders. Afolder can contain other folders. 12. Categories of OS1. Embedded Operating Systems: Used for handheld computers and smaller devices like PDAs. It is called embedded because entire OS is stored within the device in its ROM memory. Examples include Windows CE, iOS, Android and Palm OS 13. Categories of OS2. Network Operating Systems (aka NOS): Used to control and coordinate computers that are linked together. NOS are typically located on one computers hard disk in the network, the Network Server that coordinates all communication. Examples include Novell NetWare, Windows NT Server, and UNIX. 14. Categories of OS3. Stand alone OS (aka desktop OS): Control a single desktop or notebook computer. If the computer is connected on a network, it may have a client operating system that works with NOS to share resources. Examples of stand alone systems include Windows, Mac OS, and some versions of UNIX. 15. WINDOWSMac OSUNIX and Linux 16. WINDOWS Microsoft Windows is by far the most popularmicrocomputer operating system with over 80%of the market designed to run with Intel andIntel-compatible microprocessors like PentiumIV. There are a variety of versions of Windows suchas Windows NT Workstation, Windows 2000Professional, Windows ME, etc. Windows XP is the latest version of Windowswhich puts emphasis on functions over programs 17. MAC OS Introduced in 1984, it provided one of the firstGUIs. It is designed to run on Macintosh computers. Has a much smaller market share, but is stillpopular with professional graphic designers, desktoppublishers, and some home users. One of the latest versions is Mac OS X featuring aintuitive user interface called Aqua. The desktopfeatures Dock, a tool for visually organizing files. Italso has the Sherlock search tool to help locateinformation on the web & system. 18. UNIX and Linux Unix OS was originally designed to run onnetworked minicomputers. Now, its used by powerful microcomputers andby servers on the Web. Linux is one of the many versions of UNIX. Linux is open source, created by Linus Torvalds in1991. Linux is one of the most popular and powerfulalternatives to Windows. 19. Others Fact of OS Most OS are Proprietary OS:they are owned and licensed by acorporation. Examples are Windows andMAC OS. Some OS are Non-Proprietary OS:they are not owned by any onecorporation. These are also called OpenSource programs. An example is Linux. 20. UtilitiesUtilities are specialized programs that makecomputing easier. Some of the most essentialutilities include: Troubleshooting or diagnostic programs:recognize and correct problems before theybecome serious Antivirus programs: guard your computeragainst viruses and other damaging programsthat can invade your computer system 21. Utilities Uninstall programs: allow you to safely andcompletely remove un-needed programs andrelated files from your hard disk Backup programs: make copies of importantfiles in case the original are lost or damaged. File compression programs: reduce the sizeof files so they can be stored and/or sent overa network more efficiently. 22. Device DriversA Device Driver or simply a driver are specializedprograms that allow devices such as mouse orkeyboard to work with the rest of the system.Device driver works with the operating systemto allow communications between the deviceand the rest of the computer system. 23. BIOSThe basic input/output system (BIOS), alsoknown as the System BIOS or ROM BIOS(pronounced /ba.os/), is a de facto standarddefining a firmware interface.When the PC starts up, the first job for the BIOSis to initialize and identify system devices. BIOSsoftware is stored on a non-volatile ROM chipon the motherboard. 24. Application Software 25. Applications are software programs thatperform specific tasks for us. You have probablyused many different types of applications. Hereare some common ones: Activity management programs like calendarsand address books Word processing applications for creatingdocuments that are attractively formatted Spreadsheet applications for creatingdocuments to manage and organize numericaldata 26. Presentation applications for making slideshows Graphics applications for creating pictures Database applications for developingdatabases that can organize and retrieve largeamounts of information Communications programs like e-mail andfaxing software for sending and receivingmessages Multimedia applications for creating videoand music 27. 2011cokyfauzialfi.wordpress.comWhats Your Message?
