Detailed explanation-1: -The ZIP file format uses lossless compression algorithms to do exactly that. It allows you to express the same information in a more efficient way by removing the redundant data from the file. This also means it is faster to send a ZIP file.
Detailed explanation-2: -Zipped (compressed) files take up less storage space and can be transferred to other computers more quickly than uncompressed files. In Windows, you work with zipped files and folders in the same way that you work with uncompressed files and folders.
Detailed explanation-3: -Essentially, there are two main types of file compression ? lossless and lossy. Lossless compression takes your files and reduces their size without losing any information. Lossy compression reduces your file size by chopping off bits and pieces that aren’t 100% necessary to function.
