1 process at most is running.
1 process or multiple are ready.
1 process or multiple are waiting.
Some other kinds of waiting in an operating system include waiting on applications, waiting on the user, and waiting for hardware to communicate. The operating system facilities many different components to work in sync.
GHz refers to how many instructions - or cycles - a processor can process per second.For example, if you has a 2.4 GHz processor, it could do 2,400,000,000 processes per second.
One gigahertz is equal to one billion ticks per second. A computer with a 2.5 ghz processor can do 2,500,000,000 processes per second.
Processes are dictated by the operating system, not the processor. Depending on the applications you are running and the amount of memory you have, you can probably get a couple thousand running.
The Intel Pentium 4 3.0 GHz processor is a single core processor, but if you'd like to upgrade to dual core, have a look at the Intel Pentium 4 531 3.0GHz Processor Upgrade RH008AV.
It would be impossible to list every single processor model and stepping produced by Intel.
In general, applications are I/O bound or processor bound, meaning that the process is waiting for either I/O or everything else is waiting for the processor to finish working. With the speed of today's CPU's, most modern applications are NOT processor bound, meaning that we're typically not waiting for the processor to finish what it's doing. Usually we're waiting for some kind of I/O process to complete. Many times we're I/O bound when we have insufficient memory and the operating system has to "swap" an application or parts of an application out to swap space (virtual memory) on the disk. Moving an application into and out of virtual memory becomes very time consuming and is often the reason people are advised to add more Random Access Memory (RAM) to make the computer run faster.
No single type of component does this, it is done by a circuit composed of many different components.

The i7 is a 64 bit processor.
ARM processor
Yes, and no. A 1.8 Ghz processor will process things at... 1.8 Ghz. A dual core processor will process things at 1.8Ghz. A dual core, however, can process many different things at the same time alot easier and efficiently then a single core processor can. For games, applications, ect, if the program can be multithreaded, then you will see a huge increase in computing speeds for the program. As for games, anything more then 2.6 Ghz is not needed. The extra money needed to bump up from a 1.8 Ghz processor to, say, a 2.8 Ghz, would be more then enough money to buy you a much better processor.
