Compressing data means reducing the number of bits needed to represent it. Compressed data, due to its reduced
size, is a lot faster to transfer and less expensive to store, freeing up storage and increasing network capacity. Algorithms that perform data compression are known as data compression algorithms. Data compression algorithms
are divided into two categories: lossy and lossless. Lossy compression algorithms compress more than lossless
compression algorithms, but at the cost of losing some information, which can’t be recovered. Lossy compression
algorithms are typically used for audio and video files, where a loss in quality is tolerable and often not noticeable.
Lossless compression algorithms on the other hand don’t compress as much, but do not lose any data, meaning
compressed information can be exactly reconstructed back into its uncompressed form. Lossless compression
algorithms are used for data that must maintain integrity, such as binaries, text documents, and source code.
