file compression

File compression reduces the size of a file by identifying and eliminating redundant or less important data, making the file smaller for storage or faster to transfer. Think of it as packing a suitcase efficiently to fit more in less space. When you compress a file, a special program analyzes its content and creates a smaller version. To use the file, you simply decompress, or "unpack," it back to its original form. This process helps save storage space and speeds up sharing over the internet without losing essential information.
