what is a disk fragmentation?

Question

and what does it do?? Thank you!

Answer 1

Visualize a file cabinet with many folders inside. All these folders are labeled according to what is inside. Now you being neat always make sure the right papers go into the correct folder. But you have a partner who is not so fastidious. Parts of stuff that belong in one folder wind up being in five or six other folders and this drives you crazy. Instead of all the files being in the same folder, they are scattered who knows where. So now your folder is fragmented with parts of it fragmented all over. Now you have to go through every folder and rearrange it all over again. Same thing happens in the computer. The defrag program is like you when you straighten out the file cabinet. The defrag program puts all the files back into the folder in which they belong. Scattered files are called fragmented and straightened out files are defragmented.

Answer 2

this is the process of rearranging files to their original location. Here's an example: let's say that you are not very organized and every time you get a file out of the file cabinet, you leave it somewhere in the house. You need access to all of these files but you get tired running all over the house to look at the files you have moved. Disk Dfragmenter is your housekeeper. It goes around behind your messy self and re-files the files for you. The hard drive has read/write heads. The further they have to run around on the drive the harder they are working. Defragging keeps the files organized and close so the read/write heads do not have to work as hard. This means your hard drive should last longer with less problems.

Answer 3

When you store files on your hard drive, they are not always located in the same place. The more you use the files, the more scattered they become on the drive. This causes the drive to run slower trying to locate the files. This is known as fragmentation. When you de-frag the drive, it reorganizes all the files so they are all together and quickly found. That's the simple laymans version.

Answer 4

That is when file fragments are all over the disc, rather than all in one spot. Wastes time in reading the whole file. ~
It happens, when you add to a file you wrote before, and there isn't enough space to add the additional in the same place.
And the more files you have that way, the more time the reading process takes.
That's why the more file additions and changes you produce, the oftener you want to defrag your drive to recover the original speed.

Answer 5

Disc fragmentation is used especially when you do a lot of adding and deleting files from the hard drive. What it does is put those fragmented files back in the order they are intended to be.

Answer 6

Defragment is a process where ur HDD sectors get rearranged, to bring the free blank sectors together nd the filled sectors together...
