What does compression of files do?
Reduces file size to:
1) Reduce download times
2) Make best use of bandwidth
3) Reduce file storage requirements
Lossy Compression
Data is lost during compression and cannot be returned to the original state.
Lossless Compression
Data is not lost during compression. Data is encoded in a different format so original can be restored
Run Length Encoding
Condenses identical elements into a single value to show repeated runs.
E.g. AAAABBBCCDAA is compressed to 4A3B2C1D2A
Dictionary Coding
Replaces repetitive words in a sentence to dictionary values
