    Biology; Chemistry; Physics: Post your doubts here!

    I completely agree with Awesome12. But, personally I don't feel there's a need to write material beyond the scope of the 5070 syllabus. It thinks its best if you just study all the syllabus requirements as perfectly as you can and practice as many past papers as you can. After all, the examiners...

    As far as i know, yes it deals only with peripheral devices only, since it deals with requesting help from the processor which is , after all, the most powerful component in a computer. Therefore, it involves communication between peripherals and the processor only.

    Yep i agree with asadalam. The fx 991 es plus is a really great cal. You could use it to do matrices ( finding inverse, multiplication) and is also useful when finding the gradient of a tangent which usually comes in the curve graph sum.

    I have also done this question and I selected B as the answer. I suppose you did the same. However, you must consider the fact that heat maybe lost radiation through the walls especially if they're dark coloured and rough. Also, convection could also be another factor that takes away heat...
