FD Full Form in Computer

What is FD full form in a Computer?

The FD full form in Computer is File Descriptor. A file descriptor is a data structure used in the file system to represent files and directories, as well as to manage their creation and storage information for later retrieval from RAM. It is critical for file system operations and data integrity, particularly in transactional and journaling file systems, to ensure reliability.

Common functions that can be performed with file descriptors:

File descriptors allow users to conduct a variety of operations on files and input-output resources. Some frequent operations include reading data from a file, writing data to a file, locating a certain place in a file, closing a file, and checking for errors during the input-output operations. File descriptors allow applications to interface with files and alter their contents.

Why should we close a file descriptor?

Closing a file descriptor releases system resources connected with the file and notifies the operating system that you no longer require access to it. To close the file descriptor, most computer languages have a close () or comparable function. Closing file descriptors is an excellent way to prevent resource leaks. It is also possible to manipulate the properties of the file descriptor with the help of various available operations.
