Memory Calculations – in your head
Right then, after digging out my calculator and going back over everything, I have it again 🙂
I did miss out a step, here is the worked example
32 bit Address Bus – 64 bit Data Bus
- 2Address Bus * Data Bus
- 232 * 64 bits is equivalent to
- 232 * 8 Bytes
- 8 * 232 is equivalent to
- 8 * 22 * 230
- 8 * 4 * 230
- 32 * 230 Bytes
230 is a GigaByte so the answer is 32GB
Remember
- 210 = KiloBytes
- 220 = MegaBytes
- 230 = GigaBytes
- 240 = TerraBytes
- 250 = PetaBytes Continue reading Memory Calculations – in your head
