If you are referring to Intel then it is Hyper-Threading

multiprocessing
Intel has HyperThreading, and AMD uses HyperTransport, so the logical processor can run threads in parallel with other processors in the chipset. (see A+ 220-701).
Hyper-Threading Technology (HT Technology) is the brand under which Intel markets a generation of processors that can increase efficiency by improving multi-task processing, and are ideal in multi-threaded environments.
Multi threading on modern computers enables the processor to handle multiple tasks at once. This effect allows the computer to perform faster, as tasks do not have to wait as long to be completed.
Hyper-Threading
A CPU is a Processor. (central processing unit or microprocessor), a CPU alias Processor can have multiple Cores which are basically processors but they are referred to as Cores.

A core duo processor has two processor cores. A quad core contains four. Multiple processor cores is somewhat like having multiple individual processors, thus allowing your computer to handle more operations at once. For a much more detailed description of multi-core processors, you can read the wikipedia article here: http://en.wikipedia.org/wiki/Multi-core_(computing)
Because some processors are slow and cannot handle games and a certain amount of work.
All Cedar Mill and Prescott 2M processors (those in the 6xx line) support EM64T. Prescott processors with a model number of 517, 524, 531, 541, 551, 561, or 571 also support EM64T.
