What does multithreading allow a CPU to do?

Multithreading allows a CPU to act as multiple CPUs simultaneously by enabling it to execute multiple threads or processes concurrently. This is achieved through techniques such as time-slicing, where the CPU switches between threads quickly enough to create the illusion that they are running in parallel. This capability is essential in improving the efficiency and performance of applications, especially those that are designed to take advantage of multiple threads for tasks such as gaming, video editing, or server operations.

By allowing multiple threads to be processed at the same time, multithreading can significantly enhance the overall throughput of the CPU, making it more efficient in handling complex applications. This is particularly beneficial in multicore and multiprocessor systems, where each core can handle different threads simultaneously, leading to better utilization of resources and improved system performance.
