What is File Control Block (FCB)?
A File Control Block (FCB) is a data structure used by an operating system to store information related to files within its file system. The FCB contains various, but often limited, types of data such as a unique identifier, user and group permissions, type of file (e.g., character or binary), size of the file, date on which it was last accessed and/or modified, etc. The FCB is linked to each individual file in the system and functions as its representative—providing essential information about the respective file when requested by either an application or a user.
The primary purpose of an FCB is to provide access control for users and applications working with files stored in an operating system's file system. Since all actions concerning a particular file must pass through the FCB first, it can be used to regulate who has access to those files—based on whether they are authenticated users or not—by comparing them against various access control parameters held in the FCBs of those same files being referenced. Additionally, FCBs allow several different processes within the same program to open and reference different parts of that same file at any given time without stepping over each other's toes—this phenomena is known as concurrency control.
