Knowledge compression, or supply coding or bit-rate discount no matter you name, is a strategy of decreasing the bodily capability of knowledge by encoding the knowledge. As soon as the knowledge is compressed, a fewer bits are wanted to symbolize the unique knowledge earlier than compression.

In info concept and pc science, knowledge compression, or bit-rate discount or supply coding, includes encoding info utilizing much less bits than the unique illustration. The method of compression may be of two varieties: Both lossy or lossless.

  • Lossy compression leads within the discount of bits by figuring out the pointless info after which eradicating it.
  • Lossless: This compression reduces bits by figuring out them and thus eliminating statistical redundancy. No info is misplaced in this type of compression.

The process of making the size of a data file less is referred to as the data compression. If we consider the context of the data transmission, it is also known as source coding (encoding done at the source of the data before it is actually stored or transmitted) in opposition to the channel coding.
