EOF may refer to any of the following:

1. Short for end-of-file, EOF is a code placed by a computer after a file's last byte of data. EOF marks are helpful in data transmission and storage. Files are stored in blocks, and the end marker helps the computer know it has allocated enough space to store the file.

The EOF is commonly represented by pressing and holding Ctrl and pressing Z in DOS and OS/2 or pressing and holding Ctrl and pressing D in Unix.

2. In programming languages, such as C, EOF is a return value defined in studio.h that is used to indicate the end of the file.
