Distributed Networks is a distributed computing network system, said to be "distributed" when the computer programming and the data to be worked on are spread out over more than one computer. Usually, this is implemented over a network.
Distributed system is a collection of autonomous computers linked by a network that appear to the users of the system as a single computer.
These machines are autonomous which implies that these systems work independently.
Distributed Systems are perceived as a single system solving certain problems (even if in reality they are placed in different locations).
By running distributed system software, the computers are enabled to coordinate and share the activities and resources respectively.
The collection of processors can provide higher performance;
When required some processors, we can add the systems to the distributed systems.
If one machine gets faulty, other machines can still survive in the network.
One machine can have more computing power than a mainframe.
One machine in the network acts as an open system so that the resource of that system can be accessed over the whole network.
Better price than the other mainframe.
Sharing data or resources
Shared data is essential to many applications such as banking, reservation systems etc, other resources (expensive printers) can also be shared.
Facilitates human-to-human communication.
Real Time Examples:
Distributed computing has various real time example which are being in use
