Distributed Systems Definition A distributed system consists of two or more nodes, where each node is a computer system with its own memory, some networking hardware, and a capability of performing some of the control functions of an OS Thus, each node performs some OS functions Data used by an OS function may be spread across many computers Non-local data is accessed through the network Distributed Systems Distributed systems consist of four components Individual computer systems Network connecting the computer systems Distributed
