Data compression is the process of reducing the size of data to improve storage efficiency and speed up data transmission
Compression (coding)
Compression involves encoding data to reduce its size
Decompression (decoding)
Decompression involves decoding compressed data to reconstruct the original data
There are two primary types of data compression: lossless and lossy
Lossless compression algorithms enable the exact original data to be reconstructed from the compressed data
Text and executable files
Lossless compression is essential for applications where accuracy is critical, such as text and executable files
Certain image formats
Lossless compression is also important for certain image formats, such as PNG and TIFF, where data integrity is crucial
Lossy compression reduces file size at the expense of losing some original data
Audio, video, and images
Lossy compression is commonly used for audio, video, and images, where a slight loss of detail is acceptable
Streaming media
Lossy compression is suitable for streaming media, where perfect fidelity is not necessary
Data compression improves storage capacity, processing speed, and data transmission efficiency in computing systems
Sector Compression
Sector compression operates at the storage sector level to maximize disk space utilization and enhance read/write operations
File Compression
File compression is a widely used technique that applies algorithms to reduce the size of files for more efficient storage and transfer
