Distributed File System Defined

A distributed file system  (DFS) is a client/server-basses file application that contains stored data on a server and can be accessed and processed as it was stored on a local computer.

The DFS makes sharing information and files among users on a network in a controlled and authorized way convenient. This is done by giving access control and storage management controls to a server managed system. DFS is fault-tolerant and the data is accessible even if some of the network nodes are offline.

When a user accesses a file on the server, the DFS works by sending the user a copy of the file, which is cached on the user’s computer while the data is being processed. The file is then returned to the server once the data has finished being processed. This ensures that users receive the most current version of data and no conflicts arise.

DFS is used in a LAN, but it can also be used in a WAN or over the Internet.

In Data Defined, we help make the complex world of data more accessible by explaining some of the most complex aspects of the field.
