发帖数: 131 | 1 I found the computers in our open lab have more than 2GByte memory.
Is it possible? The computers are Sun ULTRA 10.
I used malloc(1024*1024*1024) twice and the pointer returned is not 0.
And third time it returned 0.
Can I belive that? |

and secondary storage (hard drive). Refer to your favorite
OS books.

possible that they have 1GB memory installed.
As a user, you definitely have 2GB memory to use.
