Sorry,but being from a non tec.generation these questions bother me.

Answer 1

If you delete a file, it is rarely actually deleted until that space is required for another file, then it is overwritten. This is why you need to be very careful when disposing of an old system and need a programme such as disk wipe to make sure all information is removed. These programmes again do not generally delete the information, but overwrite it with gibberish. The files on the system are also not placed in order - you may have one part of a file in one spare slot then another part of it somewhere else. This is where you use defragging to get the files back together and improve the speed of your system when it looks for a file. The actual drive looks like a metal rectangular case (you cannot see inside most unless you take them apart, then they look a little like a CD with an arm going over them. Hope this helps

A file will be placed in the nearest avaliable slot at the end or in the middle. files can often be in many differnt places in parts. De fragmenting a hd is a process that moves the files around so that they can be all together.
