Hello sir/ mam please send me previous year question papers and model question paper of distributed computing subject

Distributed computing is a field of computer science that studies distributed systems. A distributed system is a software system in which components located on networked computers communicate and coordinate their actions by passing messages.The components interact with each other in order to achieve a common goal. Three significant characteristics of distributed systems are: concurrency of components, lack of a global clock, and independent failure of components.Examples of distributed systems vary from SOA-based systems to massively multiplayer online games to peer-to-peer applications.
