EOF

EOF stands for "End Of File." It signals that a program or device has reached the final part of a data file or data stream, meaning there is no more data to read. Think of it like reaching the end of a book—you've finished reading all the pages. In computing, detecting EOF helps programs know when to stop reading input or processing data, preventing errors or endless loops. It's a way to reliably mark the conclusion of a data source during file handling or communication.
