 11. Read the following excerpt and fill in the blanks 
Files are stored in memory. 

On a hard disk, memory is divided into chunks called 'sectors'.

When a file needs to be stored, the operating system looks for free 
sectors on the disk. However, these sectors are rarely sequential 
(i.e. next to one another), instead they are usually scattered in 
different places across the hard disk.


If a file is broken up ("fragmented") across too many separate memory 
sectors, it becomes difficult for the hard disk to access all of the pieces 
of a file in a timely manner. This can make the computer appear to be
