Compression

Compression is a reduction in the number of bits needed to represent data.

• The compression basically makes the file smaller and, therefore, the sending of the file is faster.
• Compressing data can save storage capacity, speed file transfer, and decrease costs for storage hardware and network bandwidth.

Types of compression

1. Data compression
2. Audio compression (data)
3. Image compression
4. Video compression

1. Data compression

The process of reducing the size of a data file (or) encoding digital information using fewer bits.

2. Audio compression (data)

The compression of digital audio streams and files

3. Image compression

The application of data compression on digital images

        

4. Video compression

The compression of digital video streams and files
