Question
Discussion Board: File System Minimum Requirements: Respond to posts from three different classmates. Late: First post due on Wednesday, (-1 Th/Friday), (-2 Saturday), (-3 Sunday). Click the title to jump directly into the forum to post. Topic: Post 8 to 10 sentences Identifying one or two logical components created by the file system (or stored by the file system) on the hard drive and the roles they play in file system. Example: File/Folder attributes and NTFS permissions are used to hide and secure the files/folders.Explanation / Answer
1. Inodes – Inodes are data structures in any Unix-style file system which describe file system objects such as a file or a directory. Each inode stores the attributes and disk block locations of the object's data. Filesystem object attributes may include metadata like times of last change, access, modification, etc., as well as owner and permission data.
Directories are lists of names assigned to inodes. A directory contains an entry for itself, its parent, and each of its children.
2. File Allocation Table – The data area of a volume is divided up into identically sized clusters, small blocks of contiguous space. Cluster sizes vary depending on the type of FAT file system being used and the size of the partition; typically cluster sizes lie somewhere between 2 KB and 32 KB.
Files may occupy one or more clusters depending on its size. Hence, a file is represented by a chain of clusters. These clusters are not necessarily stored adjacent to one another on the disk's surface but are often fragmented throughout the Data Region.
