JNTUK R20 B.Tech Distributed Systems Material – Outcomes

• Explain the basics and challenges of distributed systems: Discuss how distributed systems work and the difficulties they face in terms of communication, reliability, and consistency.
• Discuss synchronization problems and global state in distributed systems: Talk about how ensuring synchronization among multiple processes across different machines can be tricky and the importance of maintaining a coherent global state.
• Explain Mutual Exclusion and Deadlock detection in distributed systems: Describe the methods used to ensure that only one process can access a shared resource at a time and how systems detect and handle situations where processes are stuck waiting for each other.
• Discuss agreement protocols and fault tolerance mechanisms: Describe the protocols and techniques used to ensure that distributed systems can reach a consensus despite failures or discrepancies among components, and how fault tolerance mechanisms help systems continue functioning even when parts fail.
• Describe features of peer-to-peer and distributed shared memory systems: Highlight the characteristics of peer-to-peer systems where each node can act as both a client and a server, and distributed shared memory systems where multiple machines share a common memory space, allowing for easier data sharing and access.
