At its core, file programming treats data as a (flux)—a continuous sequence of bytes. The module distinguishes between two primary types of files: The Architecture of Persistence: An Analysis of File
Data is read or written from the beginning to the end. This is ideal for logs or simple lists where every record must be processed in order. Module A206 Programmation fichiers
Checking if the file exists or if the program has the necessary permissions.
A critical concept is . To minimize slow physical disk I/O operations, the operating system uses a buffer (temporary RAM) to collect data before writing it in "chunks" to the storage media. 2. Access Methods: Sequential vs. Direct
