Windows 7: Assignment help on Binary

I really have to finish my computer assignment and I am confused at few questions.

1) Say Computer A has a 1GHz processor and 16-but word size. Computer B has a 2GHz processor and 32-bit word size. Compare the processing speeds of these computers quantitatively. Show calculations.

2) Conversion from true-color graphic to black and white. Explain what the conversion did in terms of pixel bytes or bits.

3) If you run the CPU simulator program, you will find that it uses the system bus 12 times. Explain how this number comes about. (You must explain why based on how cpu operates. This will involve a little arithmetic. Show all).

The last questions I believe uses the concept of



1) Fetch
2) Decode
3) Execute
4) Store.
