- noun a means of reducing the size of blocks of data by removing spaces, empty sections, and unused material
- The encoding of data so that it occupies less space and/or bandwidth. There are many algorithms used for compression, and depending on the information being encoded, space savings can range from under 10% to over 99%. Data compression can also be achieved by increasing packing density. Also called data compaction, compression (2), digital compression, or information compression.
