Defragmentation/Optimization
A computer that is poorly organized can cause it to run slower because it takes more time to locate files

Disk Utility Software
Utility software is used to maintain the infrastructure of the computer by means of anti-virus, backup, data compression, disc cleaners etc.
BackupUse of the computer compressing duplicate files in case something goes wrong such as your hard drive crashes
File ManagementFile management is the categorization of files through menus/folders so that it is easiest for an application to find ex. iTunes has folders of each song categorized so that it can open quickly with all info. presented nicely
Account & Accesibility Management

Malware Detectors & RemoversA spy-ware remover is a program that

CompressionProcess of encoding information using fewer bits than the original representation
Also called bit-rate reduction and source coding
Lossy: data is lost during compressionMultimedia (images, video, audio)
Lossless: original data is retainedText files
Lossy Compression
DecompressionReversion of compressed data
Lossless data will be decompressed to its original form
Lossy data will be decompressed to its near-original form
