Types of compression
Lossy
Reduces the amount of data needed to store a file, causing a decrease in the quality of the file
The quality can generally be varied, which is determined by how much a file is compressed
Lossy compression removes data you are unlikely to notice. such as frequencies that a human can't detect
Lossy compression is very useful for photographic images, where the colors are generally not solid, but not really for simple graphics.
Lossless

Compression techniques

The algorithm searches for a sequence of data and stores it all as one instance of the sequence, and for how long the sequence is repeated
