1. computerA computer is a general purposedevice that can be programmed tocarry out a set of arithmetic or logicaloperations automatically. Since asequence of operations can bereadily changed, the computer cansolve more than one kind of problem 2. Computer HardwareHard ware, in the computerworld, refers to the physicalcomponents that make up acomputer system.There are many different kinds ofhardware that can be installedinside, and connected to theoutside, of a computer. 3. softwareSoftwaremeans computer instructions or data. Anythingthat canbe stored electronicallyis software, in contrastto storage devicesanddisplay devices whichare called hardware 4. Utility software is systemsoftware designed to helpanalyze, configure, optimize ormaintain a computer.[1]Utility software usually focuseson how the computerinfrastructure (includingthe computerhardware, operating system software and data storage) operates 5. Utility softwareArchivers output a stream or asingle file when provided with adirectory or a set of files. Archiveutilities, unlike archive suites,usually do not include compressionor encryption capabilities. Somearchive utilities may even have aseparate un-archive utility for thereverse operation 6. Anti-virus utilities scan forcomputer virusesClipboard managers expandthe clipboard functionality of anoperating system .Cryptographic utilities encryptand decrypt streams and files.Disk checkers can scanoperating hard drive. 7. Backup software can makecopies of all information storedon a disk and restore either theentire disk (e.g. in an eventof disk failure) or selected files(e.g. in an event of accidentaldeletion). Datacompression utilities output ashorter stream or a smaller filewhen provided with a stream orfile. 8. Data synchronization utilitiesestablish consistency amongdata from a source to a targetdata storage and vice versa.There are several branches ofthis type of utility: 9. : File synchronizationutilities maintain consistencybetween two sources. They maybe used to create redundancy orbackup copies but are also usedto help users carry their digitalmusic, photos and video intheir mobile devices 10. Revision control utilitiesare intended to deal withsituations where more thanone user attempts tosimultaneously modify thesame file. 11. Disk checkers can scanoperating hard drive.Disk cleaners can find files thatare unnecessary to computeroperation, or take upconsiderable amounts of space.Disk cleaner helps the user todecide what to delete when theirhard disk is full. 12. Disk compression utilities cantransparently compress/uncompress the contents of a disk,increasing the capacity of thedisk.Disk defragmenters candetect computer files whosecontents are broken acrossseveral locations on the harddisk, and move the fragments toone location to increaseefficiency. 13. Disk partitions can divide anindividual drive into multiple logicaldrives, each with its own file systemwhich can be mounted by theoperating system and treated as anindividual drive.Disk space analyzers for thevisualization of disk space usage bygetting the size for each folder(including sub folders) & files infolder or drive. showing thedistribution of the used space. 14. Disk storage utilitiesFile managers provide aconvenient method of performingroutine data management tasks,such as deleting, renaming,cataloging, un cataloging,moving, copying, merging,generating and modifying datasets. Hex editors directly modifythe text or data of a file. Thesefiles could be data or an actualprogram. 15. Memory testers check formemory failures.Network utilities analyze thecomputer's network connectivity,configure network settings,check data transfer or logevents.Registry cleaners clean andoptimize the Windows registry byremoving old registry keys thatare no longer in use. 16. Screensavers weredesired to prevent phosphorburn-in on CRT andplasma computer monitors byblanking the screen or filling itwith moving images or patternswhen the computer is not in use.Contemporary screensavers areused primarily for entertainmentor security. 17. System monitors formonitoring resources andperformance in a computersystem.System profilers providedetailed information about thesoftware installed and hardwareattached to the computer. 18.

A touch typist never looks atthe keyboard. The fingers hit the rightkeys by force of habit. The typist isentirely focused on the text being typed,reading the words and phrases as thefingers type the text reflexively. Touchtyping can be learned by performingspecial exercises.Stage one of the process begins withlearning the home row of the keyboard(the row beginning with the Caps Lockkey).
