When I open Task Manager it shows 2 CPU History Usage Graphs (see attachment MyTaskManager1.png) but when I open Task manager on other PC it shows a Single CPU Usage History Graph (see MyTaskManager2.bmp).
What is that mean?
Help me
Hi Anam005,
In the first PC the processor is either Hyper  -thread or Dual Core or Core II Duo type processor.
That is, the processor is consist of 2 cores within it.
That’s why, in the first pc the task manager shows 2 CPU Usage History.
In the second PC, the processor has only one core inside itself.
So the task manager of the second PC displays only 1 CPU Usage History.
If your Windows Task Manager shows 2 CPU Usage History and the other computer has only 1 CPU Usage History, it means that the other computer has an older version of processor installed on its motherboard. They are the Uniprocessor PCs or single-processor computers and have fixed single cores.
They are the older versions of computers. But there are older versions of processor that has single core but uses dual processors. The use of dual processors in a single core is called HyperThreading. If you have this in your processor you can enable or disable it in the BIOS. You can use your computer as a Uniprocessor or using the HyperThreading that enables 2 processors.
New versions of processors today have dual cores, dual processors, quad processors (4 processors). They are extremely fast types of processors and are quite expensive for average users. These new versions of processors are best for gaming and heavy types of applications.
