AIM
To provide knowledge on principles and practice, underlying the design of distributed systems. This subject deals with distributed objects, file system, IPC and Remote invocation, and Distributed operating system issues, transactions and security.
OBJECTIVE
• To layout foundations of Distributed Systems.
• To introduce the idea of middleware and related issues.
• To understand in detail the system level and support required.
• To understand the issues involves in studying data and design distributed algorithms.
