A computer file appended to an email message, or an emotional bond/fastening device.

In digital communication, it specifically denotes an independent file (document, image, PDF) transmitted alongside an email message.

The story behind the word. Long before software engineers built email clients, French carpenters used atachier—literally pinning something down with a small wooden stake or tack (estache). When early email protocols allowed files to 'tack on' to text messages, the word leapt into computer software.
