How many calculations can a CPU do per second?
Ka inehia te tere karaka i roto i nga huringa mo ia hekona, a ko te kotahi huringa mo ia hekona e kiia ana ko te 1 hertz.

Ko te teitei ake o te tere karaka i te PTM, ka tere ake te mahi i nga tohutohu.
What enables several programs to run at the same time on a single CPU?
multithreading: Allows different parts of a single program to run concurrently. real time: Responds to input instantly. General-purpose operating systems, such as DOS and UNIX, are not real-time. Operating systems provide a software platform on top of which other programs, called application programs, can run.
