ZIP is a popular data compression and archival format that supports lossless data compression. For one, girls might compare it with their handbags: It supports transporting multiple files in a single pocket -- and due to their compression they take up less space this way. As the ZIP format is widely supported by most operating systems, it's one of the preferred ways of distributing multiple files -- be it in attachments with mails, or storage on web servers for download.
