Answer:
D) extents
Explanation:
Disks fragmentations in computer science refers to the cases of a file system laying out its contents in a non-continuous manner thus preventing an in-place alteration of the contents (that is the contents of the file are scattered in fragments across different location on the disk). Disk fragmentation is mostly associated with aging. To mitigate against this, modern implementation of file systems try to preallocate longer chunks of disk space, this is called extents, in this way fragmentation is avoided since a contiguous size of disk space is preallocated to the files and its contents stay together.
They are arranged the way they are because of the QWERTY layout. It was used to slow down how people typed so they wouldn't get the typewriter jammed. Hope this helps. :)
