Parallel systems are also known as what type of coupled systems?

Parallel systems are often referred to as tightly coupled systems because of the way their components interact and share resources. In a tightly coupled system, multiple processors or cores can work together on a shared task with high performance. These systems have a close interdependence and usually share memory and other resources, allowing for efficient communication and synchronization between the processors. This close coupling results in lower latency when exchanging data and quicker response times, which is essential for tasks requiring high computational power.

In contrast, loosely coupled systems communicate across a network and typically operate with their own memory. Each processor can work independently, but the interaction is less direct and can be slower due to this separation. Understanding the distinction between tightly and loosely coupled systems is crucial in operating systems as it affects performance, scalability, and design of parallel computing applications.
