What term describes the relationship between the internal speed of the CPU and the speed
of the system bus?
- A.CPU time
- B.Multiplier
- C.Differential
- D.Coefficient
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
| The internal speed may be the same as the motherboard’s speed (the external or bus speed), but it’s more likely to be a multiple of it. For example, a CPU may have an internal speed of 1.3 GHz but an external speed of 133 MHz. That means for every tick of the system crystal’s clock, the CPU has 10 internal ticks of its own clock. |
