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.
On a computer network, operating systems communicate with each other. In a distributed operating system, a single OS is communicating with itself across multiple machines.
The difference between distributed system and multiprocessor system is whether the processing units in the system share the main memory. If yes, then the system is multiprocessor system; otherwise, it's a distributed system.
A distributed computing system requires each machine attached to the network to has specific software allowing them to talk to each other. A distributed virtual systems allows the machines on a network to talk to each other without the use of central software.
distributed system is a special case of computer network.ofcourse distributed system is a network but a network may or may not be distributed.In general,a computer network is a very general term but distributed system is more specific..
In centralised tasks are done by one system and in distributed tasks are shared by the many computers
they difference is the network operating system is the type of system that a computer or -IT technology Company uses after it has trademarked it. The OPERATING SYSTEM is the home version
node is endpoint network connection device or interface between system and network. hop is a computer system
there is no proper knowledge regarding this question.
SCADA will perform supervisory action over Distributed control system to make sure that every thing is working fine.
operating system security concerns about vulnerabilities on specific operating system network system security concerns about vulnerabilities of the entire network regrdless how diverse or complex the network is.
A switch is a network connectivity device and a host is a computer system (client) on a network.
Operating system protects the computers data from viruses and hackers on the network.. network security protects all devices, servers,m computers ,mainframes on the network.
