What is Data Compression?

Data compression is the process of encoding, restructuring or otherwise modifying data in order to reduce its size. Fundamentally, it involves re-encoding information using fewer bits than the original representation.

For data transmission, compression can be run on the content or on the entire transmission. When information is sent or received via the internet, larger files, either on their own or with others, or as part of an archive file, may be transmitted in one of many compressed formats, like ZIP, RAR, 7z, or MP3.

Data Compression Uses

Most businesses today rely on data compression in some major way, especially as the functional quality of data increases, storage capacity concerns have to be resolved. Data compression is one of the major tools that helps with this. There a number of file types that are frequently compressed:

Why Data Compression is Important

The main advantages of compression are reductions in storage hardware, data transmission time, and communication bandwidth. This can result in significant cost savings. Compressed files require significantly less storage capacity than uncompressed files, meaning a significant decrease in expenses for storage. A compressed file also requires less time for transfer while consuming less network bandwidth. This can also help with costs, and also increases productivity.
