what is actually happening when you defragment your computer?

Answer 1

it places all the 1111&0000 in order.

Answer 2

When you first get your computer or a new hard drive, your computer saves data in an orderly fashion on the drive, until something is deleted. Then the space that data formerly occupied is marked as usable, and the computer puts things there, and takes stuff away from other places when you delete things, etc. This creates a situation where there's a variety of data spread out all over the drive. What defragmenting does is takes all the data and smushes it together on the drive, so that all the data is together, and all the empty space is together. This makes your drive run faster an more efficiently because it doesn't have to wander all over the drive to find things.

Answer 3

The files that make up the programs sometimes get scattered all over the hard drive. These letters, numbers and symbols have to occasionally be put back where they belong and fortunately, Defrag does that for us, making the computer run faster and trouble free. Great Question by the way. Larry

Answer 4

you will come across an entire clarification on a area like Wikipedia. it is not a competent theory to defragment your annoying rigidity too often by way of fact it may reason registry errors; usually of thumb you need to in basic terms defragment the rigidity whilst it relatively is greater desirable than 10% fragmented (possibly as quickly as each 3 months). Defragmenting the annoying rigidity takes information it incredibly is unfolded all over the rigidity in bits and products and organizes it well into huge blocks. it is going to velocity up your pc and make area on your annoying rigidity. it won't do away with or reason harm to any classes or documents (except you do it too frequently).

Answer 5

A file on your disk appears to be contiguous (all in one "lump") but is actually made up of several parts. Each part is dedicated to a file from a pool of such parts, as needed. To fetch, say, the 1000th record in a file may need several different movements of the read head as it goes through several parts. Defragmentation recopies the files on a disk so that for the most part, a file is made up of contiguous space on the disk. Reading data from the disk can be simpler (fewer head movements) and faster after defragmentation.Recently there has been new software which does the same with the enormous memory that goes with personal computers. Likewise, defragmented memory makes for faster transfer of data.

Answer 6

Defragging puts files that were written on different parts of the hard drive together - it "de-fragments" them. If most or all of a file or piece of software is close together on the disk, it can be accessed faster.

Answer 7

When you download files or whatever, the CPU scatters them around basically, when you defrag, it puts associated files together as close as possible, so that the PC doesn't have to search around as much.

Answer 8

when u defrag your hard drive what it does is takes the space left behind by files or programs you have removed or deleted and puts them together, if you watch the whole process you can see it moving the files around and opening up space for new files or programs

Answer 9

Wen you save anything on your pc, it basically gets saved in random places on your hard drive... when you defrag it arranges all of the files and the "gaps" of free space seperately... your pc should be faster and you will have a little bit of extra space... and i mean little like 5mb.

Answer 10

Nothing happens, it is just a graphic display that makes you feel you have something intelligent going on for a while, then you can take a break and get back to work later feeling refreshed

Answer 11

the data is being moved into a better order, so it easily accessed and read throughout, when you delete files you leave gaps, these gaps are removed when data is re-organised
