Dual core processor with 2GB of RAM does this mean each core uses 1GB or each core uses 2GB shared?

Answer 1

Doesnt work like that, the memory are merged into a pool, application just use the memory from teh pool whenever its needed, then relase back to the pool when done, so how many CPU doesnt matter in that sense.

Answer 2

They share it, dual core just means some tasks are separates so there is not as much stress on the processor, memory is shared though
