Compression Methods

Definition

Compression methods are techniques used to reduce the size of data files, making them easier to store and transmit. These methods eliminate redundant or repetitive information in order to decrease file size.

Lempel-Ziv-Welch (LZW) Algorithm: The LZW algorithm is a dictionary-based compression method that replaces repeating patterns with shorter codes, allowing for efficient storage and transmission of data.

Lossless Compression: Lossless compression is a type of compression where the original data can be perfectly reconstructed from the compressed version without any loss of information.
