Lossless and Lossy Compression

Compression reduces the number bits of the file making the storage capacity lower and the data transfer of the file quicker. This is useful because more data can be stored and transfered in a smaller amount of time.

There are two types compression, Lossy and Lossless compression.

Lossy

With Lossy compression, some of the data is lost and cannot be recovered greatly reducing the file size. Compressing a file with lossy, it reduces the quality of the image/video. This cannot be used on text and executive files.

Lossless

With Lossless compression, none of the data is lost because it is encoded in a different way, which means it can be turned back into and can be used on all types of data. It is however less effective than lossy compression at reducing the file size and is mostly suitable for documents and executable files.
