What is a File System
In a computer, a file system – sometimes written filesystem – is the way in which files are named and where they are placed logically for storage and retrieval. Without a file system, stored information wouldn’t be isolated into individual files and would be difficult to identify and retrieve
File Access Mechanisms
File access mechanism refers to the manner in which the records of a file may be accessed. There are several ways to access files - Sequential access, Direct/Random access, Indexed sequential access.
File System Implementation
File system implementation defines how files and directories are stored, how disk space is managed, and how to make everything work efficiently and reliably. File system organize storage on disk drives, and can be viewed as a layered design.
Advantages & Disadvantages File Allocation Methods
The allocation methods define how the files are stored in the disk blocks. There are three main disk space or file allocation methods - Contiguous Allocation, Linked Allocation, and Indexed Allocation. Advantages and disadvantages are seen by efficient utilization of disk space and quick access to file blocks.
