The actual size of the hard disk.
The actual size of the core memory.

GENERAL OBSERVATION : Many of the doubts on the working of the operating system / the Compiler are automatically cleared as you proceed to the later Sessions in the course. In any case, the last section of Questions and Answers Audio should answer almost all doubts. One can listen to the answers even in the middle of the course provided one locates the exact Question in the QA section. You are advised to run through the 3 Question Banks to check if the doubt you have is covered by a Question.
