📚File compression reduces the size of files, creating smaller versions that use less space.
🌐There are various file compression formats available, including zip, gzip, 7z, raw, tar, and bzip2.
📈File compression methods can be lossy (data discarded) or non-lossy (maintains all data).
💡Lossless compression methods identify repeated data patterns and replace them with codes.
🔍Popular compression algorithms include Huffman coding and LZ77/LZ78.
What is file compression?
—File compression is the process of reducing the size of a file by creating a smaller version that uses less storage space.
What are some popular file compression formats?
—Some popular file compression formats include zip, gzip, 7z, raw, tar, and bzip2.
What is the difference between lossy and non-lossy compression?
—Lossy compression discards some data to achieve higher compression, while non-lossy compression maintains all data.
What are some common compression algorithms?
—Common compression algorithms include Huffman coding, LZ77, and LZ78.
Which file compression format is the most efficient?
—The efficiency of a compression format depends on the type of content being compressed. Different formats may excel in different scenarios.
