Distributed computing is a computing model where tasks are divided among multiple computers, which work together to solve a problem. Each computer, or node, processes its part of the task independently, allowing for faster computation and efficient resource use. This approach is often used in large-scale applications, such as scientific simulations and data analysis. In a distributed computing system, nodes can be located in different physical locations, connected through a network. This setup enhances reliability and scalability, as the system can continue functioning even if some nodes fail. Examples of distributed computing include cloud services and peer-to-peer networks.
