# Calculate Total Addressing Capacity Including Unused Memory Zone

Question

A computer system uses 20-bit address bus and can address an 8-bit wide memory. The memory of this computer system contains 2 × 32 Kbytes ROM (ROM1, ROM2) and 2 × 16 Kbytes of RAM (RAM1 & RAM2). The memories are ordered in an interlaced manner – ROM1, RAM1, ROM2, and RAM2 and form a contiguous block of memory starting at address 0. The rest of the address range after RAM2 is not used.

(a) Calculate the total addressing capacity of this computer system, including the unused memory zone.
(b) Draw a memory map for the computer system. Indicate the starting and ending addresses in hexadecimal for each block of memory and any unused space. Show how the memory addresses are obtained.

Summary

The question belongs to Computer Science and it discusses about calculating the total addressing capacity of a computer system including unused memory zone.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
