Quick teaser

I lifed this from the 2011 paper it’s question 13

(b) The computer has a maximum addressable memory of 16 Gigabytes. Its address bus width is 32.
(i) Calculate the width of the data bus.
(ii) State why computers do not come with the maximum addressable memory installed.
(iii) State the effect that adding one new line to the address bus would have on the maximum addressable memory.

I thought it was a very good question. I will post the solution to it tomorrow, feel free to comment with your answer but I don’t want you to copy and paste it from the Marking Instructions above.

Well the wind has picked up and we are off school. To prepare for tomorrow’s lesson you can read over the scholar section on computer structure we are working through. Remember, I have a useful report section that allows me to check who has read this and who has not.

You can also head over to revise computing and try their resources.

Finally, there are a few of you still to hand in this weeks programming homework, so you could finish that off.

Plenty to keep you busy and out of the weather, stay safe and I’ll see you tomorrow.
