The CPU works by the power of unicorns and pixies and fairydust

The CPU checks the ROM, takes instructions from the RAM and cache, translates data to binary and processes the data and carries out the instructions in op-code

The CPU checks the hard disk for applications running background application software and cancels operations

Which is better and why: 2 CPUs or 4 CPUs?

Select the correct answer(s).  

(0/0)

2 CPUs because not many applications have been developed for multiple processors so users don't need quad core yet

4 CPUs means quad core so it has a higher clock speed than 2 CPUs

2 CPUs which means dual core so the user can do twice as much

4 CPUs which means quad core because the user can use more applications than dual core as more have been developed to take advantage of multiple processors

none
