What has the unit Hz to do with CPUs and where is the connection of CPU’s Hz and RAM’s Hz?

Question

RAM = memory

CPU = main processor

Hz = hertz <- frequency’s unit

In: Technology

Answer 1

* Hz is a measure of the frequency of some repeated cycle.
* In the case of CPU and RAM, it’s each devices’s respective clock speed.
* Each device does some operation every time the clock pulses, so the frequency measured in Hz is the rate at which it does something.
* For the CPU this is the rate at which it processes instructions. (Some take more than one clock cycle, some only take one).
* For the RAM this is the rate at which it does the work of fetching data and refreshes the data stored. Again some or all of those operations may take more than one clock cycle.
