what does defrag mean?

Answer 1

It means run a program that will put all of the parts of each file into convenient locations for easy access.

When a file is written on a disk it is written onto locations that come under the disk write heads in sequence while writing. That means the next read access is very fast also. If instead that file is just fit into whatever space happens to be left on the disk at the time of writing not all parts will be in that fast-to-read positioning.

Defragging takes each file and moves any parts of it that are not sequential so that read access will be rapid.

Answer 2

Defrag or Disk Defragmenter is a program included with most versions of the MS-DOS and Microsoft Windows operating systems starting from MS-DOS 6.0 (1993). Defrag.exe defragments a file system in a hard drive.

Defragmentation has been part of disk optimization since disk optimization stabilized in 1975. Few, other than Norton (Symantec) and Microsoft, have shipped defragmentation programs separate from disk optimization methods.

MS-DOS up to version 5 and Windows NT through version 4 did not come with a defragmentation utility.

In the MS-DOS world there were several after-market disk optimizers. The most famous, the Microsoft Defrag utility (licensed from Symantec, makers of the Norton Utilities) only did defragmentation. Microsoft's Defrag was criticised as being slow and using memory inefficiently. Norton's Speed Disk was much better (with more organizational options, and a 30% speed improvement). A shareware program called Disk Organizer was faster than most other programs and became quite popular for several years.

When Defrag was shipped for free with MS-DOS 6.0, the use of the alternative commercial products became less frequent, because customers were unable to justify the additional expense.

Windows 2000 and Windows XP include a stripped-down licensed version of Diskeeper Corporation's, (formerly Executive Software), Diskeeper.

The purpose of Disk defragmenting is to optimize the time it takes to read and write files to/from the disk by minimizing head travel time and maximizing the transfer rate. The used techniques include:

Moving all the index or directory information to one spot. Moving this spot into the center of the data, e.g. one third of the way in, so that head travel to data is halved compared to having directory information at the front.
Clustering files around the directory area.
Moving infrequently used files further from the directory area.
Obeying a user provided table of file descriptions to emphasize or ignore.
Making files contiguous so that they can be read without unnecessary seeking (defragmentation

Answer 3

defrag is short for 'Defragmentation'. Some files are moved in parts to different sections of the hard drive, which is NOT the directory. The directory and the sector are 2 different things. When you run the Disk Defragmenter on a PC, is will move these file parts from different sectors of the hard drive to the original file, making your computer much faster when accessing files.

Answer 4

It is an abbreviated form of defragment, which means to take all of the missed placed files on your computer (fragmented files) and reorganize them and place them in the proper locations. Now you have (defragmented files)

Answer 5

A disk defragmenter is a computer program designed to increase access speed (and sometimes increase the amount of usable space) by rearranging files stored on a disk to occupy contiguous storage locations. Disk defragmenters are available for many platforms, the most common being those included with operating systems (i.e. Microsoft Windows), utility packages (like Norton Utilities), or other standalone defragmenters (like PerfectDisk or Diskeeper). Many offer advanced options, such as sorting by last access or modification date to decrease access time for most commonly accessed files.

Answer 6

To defrag, or "defragment", is basically when your computer takes files that are spread or unorganized and puts them together to provide you with more space.

Answer 7

it runs a program that organizes the disc space of your hard drive so your computer runs more efficiently. If you use your computer a lot, check every couple of months to see if you should defrag.

Answer 8

defragment - in computer terms it means arranging the data on your hard drive to group associated data together physically on the disc. It saves processing time.

Answer 9

to reorganize the storage space on a hard disk by consolidating similiar files thereby optimizing the performance of the hard disk
