Which is it that defines the speed of the comp, or is it both?
Good Question, here is how it goes.
The CPU is designed to run at a certain frequency (Speed) lets say 2.5 GHZ by its manufacturer. (Intel/AMD.. etc.)
The CPU is inserted onto the motherboard, and the motherboard has to be told what the frequency (Speed) of the CPU is so it can register...2.5 GHZ! (Most of the time this is done automatically by the motherboard but there are motherboards out there that let you set this up manually.)
The motherboard runs the CPU at the specified speed.
Here is a simple illustration: You are in a car with a V8 440 engine. How fast can you go?? It depends on how much gas you give the car. The more gas, the higher the speed. So even though the engine (CPU) has the capacity of going fast, it is up to the accelerator to proportion the gas to the engine (MOBO).
Cars have a limit on the top speed (lets say 160 MPH) this is regulated by the car's computer. The MOTHERBOARD is what regulates the speed of the CPU. The motherboard is what controls how fast your CPU will run.
If you can find a way to tell the motherboard to crank up the juice on your CPU... Your 2.5 GHZ CPU can work at 3.2 GHZ. This is a technique called Overclocking.
So, the speed of the computer goes hand in hand with the CPU and the motherboard.
Also, if you intend on overclocking your computer, you have to make a few adjustments, you have to make sure your CPU has proper cooling.
What happens to a car that is driven and it overhearts???? It shuts down. Same holds true for a CPU.
