File Control Block

A File Control Block (FCB) is a data structure used by operating systems to manage and store information about files. In the context of file systems, the FCB contains metadata that describes the attributes of a file, such as: 1. **File Name**: The name of the file. 2. **File Size**: The size of the file in bytes. 3. **File Location**: The location on the disk where the file's data starts and how to access it.
