Distributed Computing is a model where multiple interconnected computers share a unified computing workload, enhancing efficiency and performance. Coursera's Distributed Computing catalogue teaches you about this paradigm that forms the backbone of modern digital infrastructures. You'll learn everything from the fundamentals of distributed systems, principles of concurrency and synchronization, to designing scalable and robust distributed architectures. Furthermore, you'll explore key topics like fault tolerance, distributed databases, and cloud computing. By mastering these, you're not just understanding the core of internet services like web search, social networks and cloud computing, but also gearing up to effectively manage data at scale, handle system failures, and distribute processing power for real-time applications.
