Notes:

Source:

Distributed Systems covers core concepts, models, and object/file communication (RPC, RMI, DFS, naming services), along with OS support and middleware (CORBA). It explores time, coordination, replication, and transaction/concurrency control in distributed environments, plus fault tolerance and real-world case studies (CORBA, Mach, JINI, TIB/Rendezvous).

The objective of the course is to be familiar with different aspect of the distributed system, middleware, system level support and different issues in designing distributed algorithms.
