We have a virtual memory system with eight virtual pages and four physical page frames. The page size is 1024 bytes. The page table is set up as follows: Present bit Page frame field Disk address 01001100111 01001100011 10001100111 01010100111 10011001110 Page # 0 01 2 3 4 0 0 01 10 0 0 01001100001 11011100111 Given the above information, determine the main memory address for each of the following virtual addresses (note that these are decimal values): a) 0000 b) 1024 c) 2048 d) 5120
