What is the main focus of distributed computing?

The main focus of distributed computing is on distributed systems, which are collections of independent computers that appear to their users as a single coherent system. This approach enables computers in different locations to work together on a problem by coordinating their actions through a network.

In distributed computing, tasks are divided among multiple systems, which communicate and collaborate to achieve a common goal. This model can enhance performance, reliability, and scalability of applications by leveraging resources across multiple machines rather than relying on a single computer.

While parallel processing and data storage solutions are relevant concepts within computing, they do not encapsulate the broader framework and objectives of distributed computing as effectively as distributed systems do. Distributed systems can incorporate aspects of parallel processing to optimize tasks and may also involve considerations for data storage; however, without the context of distributed systems, those concepts alone do not represent the holistic focus of distributed computing.
