Technology

A wireless network is termed as technology that allows two or more computers, to communicate by enabling file sharing, printer sharing, internet connection, and using standard protocol but without the use of a network cable. A distributed file system (DFS) is a clientserver based architecture that allows clients to access and process data stored on a server as if it were on their own computer.

Distributed file system (DFS) in windows server 2003
The Distributed file system solution in Microsoft Windows 2003 provides two technologies DFS Namespaces and DFS Replication which together offer simplified access to files and WAN friendly replication.

Distributed File Systems will offer a number of advantages to the hospital. Through data distribution, it can be used to publish documents, software, and line-of-business data to doctors remotely. A folder is hosted by multiple servers so when a doctor requests a file through his phone, he is directed unknowingly to the folder which he should access fast. Through file sharing, a doctor can access files wirelessly because the process of setting up replicated folders is simplified in Windows Server2003by the introduction of replication groups and replicated folders. DFS Replication also allows the hospital branches with slow WAN connections to participate in replication using minimal bandwidth.

Conclusion
Since the doctors need up-to-date critical information remotely as fast as possible and DFSs typically use file or database replication (distributing copies of data on multiple servers) to protect against data access failures, all files are accessible to all users of the global file system and organization is hierarchical and directory-based.
