Cluster Computing is a type of computing where multiple computers, known as nodes, work together to perform tasks more efficiently than a single machine. These nodes are connected through a network and can share resources, such as processing power and storage. This setup allows for improved performance, reliability, and scalability, making it ideal for handling large datasets and complex computations. In a cluster, tasks are divided among the nodes, which can operate simultaneously, reducing the time needed to complete jobs. This approach is commonly used in various fields, including scientific research, data analysis, and web services, where high availability and processing speed are crucial.
