Compression algorithms are methods used to reduce the size of data, making it easier to store and transmit. They work by identifying and eliminating redundancy in data, enabling a more efficient representation. There are two main types of compression: 1. **Lossless Compression**: This type of compression allows the original data to be perfectly reconstructed from the compressed data. Lossless compression is commonly used for text files, executables, and some image formats (like PNG).
