The .gz filename extension refers to the GZIP file format and compression/decompression utility of the same name which was initially released in 1992. It is the extension given to files compressed using the gzip utility. Unlike other compression tools of the time, gzip was originally intended to be used as a tool to compress a single file as opposed to multiple files or entire directories compressed as a single archive. As a work around, multiple files can be archived using the TAR archive file format, then that single TAR archive would then be compressed using the GZIP format. This would give the file a filename extension of .tar.gz.
The .ZIP file extension format is a file archive and data compression format originally developed and released in 1989 by Phil Katz. With compatible zip format software, a file or a group of files can be packed (compressed) into a single .zip archive which can later be unpacked (decompressed). The zip file archive format facilitates the distribution of multiple files as single archives particularly over the internet and networked systems. Many operating systems have native support for the file format and can usually open zip archives without the need for third party software. Microsoft windows for instance has had native support for the ZIP format since Microsoft Windows 98, similarly Apple's Mac OS includes ZIP support through its default archive file handle Archive Utility.

The GZIP format uses the DEFLATE algorithm for compression. A file in this format consists of a 10 byte header containing the version number, timestamp, and magic number. Other blocks include optional extra header blocks, the DEFLATE payload, and a CRC-32 checksum contained in an 8 byte footer.
Many other common filename extensions use the ZIP format in one aspect or another, for example JAR, .WAR, .DOCX, .XLXS, .PPTX, .ODT, .ODS, .ODP all utilize the ZIP format. The ZIP format provides for data integrity through the CRC32 specification with support for digital signatures. It also supports multiple compression algorithms but commonly utilizes the DEFLATE algorithm.
