The ZIP compression file format has been quite common in the computing world today. It is even incorporated within Mac OS itself. Back when storage space was small, compression was mainly used to group tons of files and divided into smaller files to fit into diskettes. Now, compression is mainly used to group files together as one file. You can zip files in Mac OS either using the UI or through the command line. This neat article Create ZIP Archives in Mac OS X has some great tips and insights when doing zip compression in Mac OS. When using zip compression, Mac OS X file elements are retained if encoded and decoded using the correct tools. Compression can save storage and bandwidth (when sending or downloading files in the internet). The zip format can be decoded on nearly any system which means compressing it in zip format can always be read in other systems that support the file format for compressing and decompressing files.
Zip compression in Mac OS has some cons of its own. The Finder does not support the creation of encrypted archives. What it is capable of, is only the standard compression. There are no file checksums to verify content as well and the Finder does not support modifying existing archives. Still, despite these cons, the zip compression in Mac OS provides users a quick and nifty tool to compress groups of files together quickly and easily.
