Talk:Fragmentation (computing)

compaction
I have just gone through the article and i was really wondering how would if i insert a setion about compaction (it removes external fragmentation by moving all allocated blocks to one end and free blocks to other) below the external fragmentation?

I mean when you disscuss the issue of external fragmentation you should write about how it can be removed. Prashantgonarkar (talk) 03:39, 14 October 2011 (UTC)

Terms Used
I have just read through this article and was wondering whether file fragmentation is actually a "phenonemon" or is there a reasonable explanation for why it occurs?

 * The 'Data fragmentation' section tries to explain it. See the File system fragmentation article if that was unclear. -- intgr [talk] 17:32, 7 May 2009 (UTC)

Internal Fragmentation
I recently reverted an edit that turned the Internal Fragmentation section into the text below. This text might have some useful contributions, but it's nowhere near good enough to replace the existing text yet.

External fragmentation a weakness of “certain” algorithms?
“It (external fragmentation) is a weakness of certain storage allocation algorithms, when they fail to order memory used by programs efficiently” – surely it is a weakness of all general purpose algorithms, and any that fails to adequately anticipate sequence of (de)allocation operations? If so, this should be changed – or am I missing something? PJTraill (talk) 10:35, 4 November 2017 (UTC)
 * One approach to avoid external fragmentation is to move surviving objects such that they are stored contiguously in memory. This is possible only for programming languages where each pointer is well-defined and where all pointers can found. Then this could be done using a garbage collector that is free to move objects. Alternatively, you can work with allocations of fixed memory units where objects are not necessarily stored contiguously in memory (see ). This, however, requires compiler support. --AFBorchert (talk) 11:33, 17 December 2020 (UTC)

'File slack' and 'slack space'
File slack and slack space both redirect to Fragmentation (computing), but these terms do not appear anywhere in the target article. – Tea2min (talk) 08:21, 9 July 2018 (UTC)

File system fragmentation
I didn't want to attempt major surgery to this article, but there already is an article File system fragmentation that talks about problems with external storage. I would suggest that this article concentrate on main storage fragmentation and eliminate (or merge) the material on file system frag. Peter Flass (talk) 15:45, 15 July 2021 (UTC)
