How does communication takes place in a distributed system?

Distributed systems depend on the networking for their functionality. A network is a communication path among two or more systems by being able to communicate distributed systems can share computational tasks and provide a rich set of features to users.

            Network varies by the protocols are in use, the space between nodes, and the transport media TCP/IP is the mainly common network protocol. Mainly operating systems support TCP/IP including the windows and UNIX operating systems. To an operating system a network protocol simply requires an interface device a network adapter, for instance with a device driver to manage it as well as software to package data in the communications protocol to send it and to unpackage it to receive it.

             Networks are typecast based on the space between their nodes. A local area network (LAN) is present within a floor, a room or a building. A wide area network (WAN) typically exists between buildings, cities or countries. A metropolitan area network (MAN) possibly link buildings within a city. Bluetooth devices communicate over a small distance of several feet, in fundamental nature of creating a small area network.

When computing devices are linked to cellular phones they create a network. Even extremely short-range infra red communication can be used for networking. These networks also differ by their performance and reliability.
