Utility Software
Defragmentation software
Hard disk drives (magnetic) become fragmented when files cannot fit in gaps left by previously deleted files
Defragmentation rearranges the fragments so that they are all in contiguous blocks (next to each other on the disk)
-
Reading
The actuator head on the drive does not have to physically move as far to get the next part of the file

Compression software
WinZip - allows you to add files to a zip folder, which reduces storage space so the files can be emailed
Lossy/lossless - lossy removes some details e.g. some shades not visible to the human eye to reduce file size. Lossless - stores the data in a compressed format
System information
-
e.g. temperature, free memory, network speed, % processor used
Diagnosis utility
-
e.g. missing drivers, network connection
