File system
From Simple English Wikipedia, the free encyclopedia
A File system (or filesystem) is a way of storing data. This data is usually organised in Computer files. Below the file system there is usually a physical device where the files are stored. This might be a harddisk, and USB flash drive, a Compact disc or DVD. The file system might also talk to a remote server over a network where the file is stored. The file-system might also only use RAM to store the flies.
The underlying storage mechanism usually has no concept of a file. A harddisk knows of disk blocks, whiich are numbered in a certain way. These disk blocks contain binary data (usually:large numbers).
The file system does the translation between the large numbers, and the view the users see, that is that of files, organised in a certain way.
