File
A computer file is a named collection of data, like a document, image, or program, stored on a device like a hard drive or flash drive. Files are the basic units for storing and retrieving information, and are identified by a name and an extension that indicates their type (e.g., .txt for text or .jpg for an image). Different types of files exist for different purposes, from text documents and spreadsheets to videos and executable programs.
