Parallel computing is a type of computation where multiple calculations or processes are carried out simultaneously. This approach divides a large problem into smaller, manageable tasks that can be solved at the same time, significantly speeding up the overall computation. It is commonly used in fields like scientific simulations, data analysis, and machine learning. In parallel computing, multiple processors or computers work together to solve a problem more efficiently. This can involve using multi-core processors in a single machine or connecting several computers in a network. By sharing the workload, parallel computing can handle complex tasks that would take too long to complete on a single processor.
