File Handle
A file handle is a unique identifier used by an operating system to manage open files. When a program opens a file, the system assigns a file handle, which allows the program to read from or write to the file without needing to know its location on the disk. This abstraction simplifies file operations and enhances security.
File handles are essential in programming, especially in languages like C and Python, where they facilitate file manipulation. They help ensure that multiple programs can access files simultaneously without conflicts, as each program uses its own file handle to interact with the same file.
