Explanation:
Detailed explanation-1: -Compression reduces the size of a file, often without appreciable loss of information. It can be either lossless or lossy. A smaller-sized compressed file can be restored to its larger form–in its entirety or with some data loss, depending on the compression type–by decompression.
Detailed explanation-2: -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.
Detailed explanation-3: -ZIP is an archive file format that supports lossless data compression.
