Distributed file system
Distributed File System
An HTML file designed to be distributed across the web is called a webpage.
The operating system (Windows, Linux, MacOS, etc.) is the basic software on your computer and that it just controls the file system on your hard drive.
There's no particular requirements on how deep a directory needs to be or should be. The directory can be any depth, subject to file system limitations.
The traditional industry standard is basic storage.
That's the compiled Java file, the one that can be distributed to the end-users.
NFS stands for Network File System: a network file system protocol allowing a user on a client computer to access files over a network in a manner similar to how local storage is accessed. NFS works over the IP network so it communicates via Ethernet. Computers accessing NFS storage will communicate via their NIC (network interface card). DFS stands for Distributed File System: In general terms, is any file system that allows access to files from multiple hosts sharing via a computer network. This makes it possible for multiple users on multiple machines to share files and storage resources. NFS is considered one of many different types of NFS. So DFS is more of a generic term.
A traditional file system can deliver routine scheduled reports after extensive programming efforts, but it cannot deliver ad-hoc reports or respond to unanticipated information requirements in a timely fashion.
New Technology File System (NTFS) and High Performance File System (HPFS),NTFS supersedes the FAT file system as the preferred file system for Microsoft's Windows operating systems. NTFS has several improvements over FAT and HPFS (High Performance File System) such as improved support for metadata and the use of advanced data structures to improve performance, reliability, and disk space utilization, plus additional extensions such as security access control lists (ACL) and file system journaling. NTFS v3.0 includes several new features over its predecessors: sparse file support, disk usage quotas, reparse points, distributed link tracking, and file-level encryption, also known as the Encrypting File System (EFS).

in ths type system all the computation are distributed among several processors. distributted system are also reffered as loosely coupled system because here the processors do not share memory or a clock . instead each has is own local memory. its sharing the resource.Realibity:- it means in distributed system, if one site fails reamaining sites will share the work of failed site.Communication- when many sites are connected to one another by a communication network, the process at different sites have athe opportunity to exchange information. a user may intiate file transfer file or communicate.navin sharmaB.sc it
