Q

A CPU feature that allows two or more instruction threads to execute independently while sharing the same process resources. Splits an app over multiple CPU cores. Dividing up work for simultaneous processing. Instead of giving a large workload to a single core, threaded programs split the work into multiple software threads. These threads are processed in parallel by different CPU cores to save time. Executes multiple threads in a single process simultaneously.
