Hard Disk Drive Fragmentation

Internet Cache (Temporary Internet Files)

 


Hard Disk Drive Fragmentation

Over time by adding and removing information from your computer your hard disk drive (HDD) becomes fragmented.  Fragmentation simply means that there are piece of information scatter semi-randomly, yet controlled, all over the place.  Your HDD starts to look a lot like the pencil drawer in your desk.  You start out neat and organized but as you use the drawer, adding things and removing things, it starts to become more and more of a chore to find what you are looking for.  It’s all there and safe just disorganized.  Your HDD has the same problem. 

So, periodically we need to take action and reorganize it to speed things up.  The best part is that, unlike your pencil drawer, the system will do this for you if you use the defragmentation tool provided in Windows XP.

This is a over-simplified description of the problem.  If you want to learn more about fragmentation follow the link below.  If that doesn’t give headache you can always do a search on “fragmentation” on the Internet.

Internet Cache (Temporary Internet Files)

A significant amount of the graphics information (pictures) on any website remains static: more in the past than today, but still a portion.  Because of this Internet Explorer (IE) stores some these files on your hard disk drive (HDD).  The next time you go to that site, IE looks at the files it has in storage and compares them to the ones on the site and uses the newest ones.  If the copy of the file in its storage (cache) is the newest one it uses it instead of downloading it again.  This saves the time needed to download the graphics from the website.  This is called caching.  In theory this is a good thing as it can improve your Internet experience.  With modern broadband connections like cable modem and DSL it isn’t so important today because of the speed with which the data can be retrieved, it does help some though.  Unfortunately, it also has a tendency to build up an accumulation of files that are never used again. 

In order to clean up this wasted space one should periodically delete the files that Internet Explorer has cached.
