Setting an FSB speed is related directly to the speed grade of memory a system must use. The memory bus connects the northbridge and RAM, just as the front-side bus connects the CPU and northbridge. Often, these two buses must operate at the same frequency.
Frequency refers to the number of occurrences of a periodic event per time and is measured in cycles/second. In this case, there is 1 cycle per 2 seconds. So the frequency is 1 cycles/2 s = 0.5 Hz. 6.
Frequency is the number of waves that pass a point in a second. This is affected by how quickly the wave source is vibrating, which determines how close the waves are together. For sound, the higher the frequency, the higher the pitch of the sound. The lower the frequency, the lower the pitch of the sound.
