what is the use of defragmentation that is seen in the peformance and maintenance optin in the computer?

Answer 1

defragmentation move your files in a position that is useful for your hard disk and windows seek...

when you save a file, the data of this file isn't saved in the some aera of the disk!so, if you want to reopen that file windows must search all part of this file in all hard disk.

defragmentation improve your disk to have the best performance in seraching that it can!

sorry if my english isn't good

good bye!

Answer 2

When your computer is new and shiny, the files on the disk are tidy and well-organised, lined up one after another, and easy for the operating system to find.

When you start to use it, though, the files are changed and rewritten... they change in size, and won't fit back in their original space on the disk, so they are broken down into manageable "chunks" and the chunks get written elsewhere on the disk, with a look-up table being maintained to tell the operating system where the various bits of each file are stored.

As time goes on, files get more and more "fragmented", and the operating system spends more and more time on simply keeping track of where everything is. Eventually, this creates a noticeable burden on system performance.

There comes a point where a system may just grind to a halt because it's using up all its resources on tracking fragmented files.
(I've worked on customer systems which took up to half an hour just to boot, solely because of this problem)

To avoid this happening, you run the Disk Defragmenter from time to time... either when fragmentation gets to about 10%, or on a regular maintenance schedule - say, once a week, for a domestic PC running Windows, as an example.
The "defrag" process will work its way across the disk, finding all the fragments of each file in turn and compacting them all back into one contiguous, easy-to-manage block.

There are, let it be said, arguments against defragmentation, but I feel that for most users, the benefits outweigh the problems

Answer 3

Defragmentation re-organizes your files so that each file is only in one piece. It speeds up the rate at which files can be accessed, since your computer doesn't have to search all over the drive for pieces of the file and put it together when you want to use it.

It also more efficiently uses the space on your hard drive and so may result in slightly more free space to be available after the defrag.

Answer 4

Imagine this, when you move to a new home, you need to buy stuff for your new house. you can't decide on where to place all these stuff so all these ends up in your living room.

Thats particularly what is happening in your computer. When You Install stuff in there, some files are not properly stored in their designated folders so they just get scattered around your computer's hard drive. Because of these scattered files, the computer needs more time to find the necessary files that's why it runs slower. But If you defragment your system, all those scattered files will be placed back to their proper locations thus making your computer run faster.

So I suggest you defragment your computer once every 2 weeks or every after new software installations.

Hope This Helps...

Answer 5

Reading and writing data on a heavily fragmented file system is slowed down as the time needed for the disk heads to move between fragments, and waiting for the disk platter to rotate into position, is often fatal to throughput (see seek time and rotational delay). For many common operations, the performance bottleneck of the entire computer is the hard disk; thus the desire to process more efficiently encourages defragmentation. Operating system vendors often recommend periodic defragmentation in order to keep disk access speed from degrading over time.

Fragmented data also spreads over more of the disk than it needs to. Thus one may defragment in order to compact data storage before splitting a single partition into two or more partitions

Answer 6

It's like Humpty Dumpty. Files can get fragmented over many areas of your hard drive. So the defragmenter puts them back together again (like they tried to do with Humpty Dumpty after he fell off the wall). That makes your hard drive and computer operate faster and more efficiently.

Humpty Dumpty sat on a wall.
Humpty Dumpty had a great fall.
All the king's horses and all the king's men
Couldn't put Humpty together again.

Answer 7

It moves files that are linked together physically closer to each other on the hard drive. This decreases the amount of time the computer needs to search for files. So say you put your favorite game on your computer. Over time, the files that make up your game while listed in one place are eventually moved all over the physical surface of the hard disk. When you go to play that game, the computer has to do a lot of searching to find all those file causing the game to run slowly and lag. Defragmenting moves all those files together so that the system can find them easily and run smoother.

Answer 8

When you install a file. It goes to one place. Slot 1. If half of the files go to slot 1 and half go to slot 56. It takes time. Because Slot 1 needs to run and go to slot 56 and pick up the files and run to the memory disk, input all the files and run the program. But if you defragment the disk, it compacts meaning pushes files to gether and then places a programs files with the rest of the files. So that group 1 can run to slot 3 faster than 56 and then the program will start fatser.

Any questions?

Answer 9

Your hard drive's information is normally disorganized/split up. For example, you may have 1 GB of free space, but it is split up in 10 segments of 100 MB each. If you then download a movie that is 700 MB, the file has to be split up into 7 segments of 100 MB each on the hard drive. In Windows it still looks like one file, but as it's playing, it's jumping from each segment. Defragmenting your hard drive removes these 'fragments,' by reorganizing the data so that your 700 MB video file is sequential/all-in-one-piece, saving processing time, and hard drive space (since you don't have to keep track of the locations of the different segments of the file)

Answer 10

it puts the scattered (by the use - it happens and you can't prevent it) pieces of all files back in more easy to access places. this helps your PC to access files at optimum speed.
you should defragment once every two weeks or once a month if you don't use your PC very much.
i would suggest a program like Diskeeper, which is MUCH faster than Windows Defragmentation tool
