Understanding File Formats

File formats are standardized ways that information is encoded for storage in a computer file. Each format serves a specific purpose and can include various types of data, such as text, images, audio, or video. Understanding the structure of file formats is crucial for effective file management and data sharing.

A file format is defined by its file extension, which is the characters following the last dot in a file name. For example, in the file name "document.pdf," the file extension is ".pdf," indicating that it is a Portable Document Format file. Each file format has its own specifications and characteristics that dictate how the file can be used.

How File Formats Affect Usability
