MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Another difference between ROM and RAM is the amount of space they contain. ROM chips can only store several megabytes (MB) of data, usually amounting to between 4 and 8 MB per ROM chip. RAM chips can store multiple gigabytes (GB); this storage often ranges from 1 to 265 GB per RAM chip.

Detailed explanation-2: -So from above equation lines required are 12.

Detailed explanation-3: -Given the size of memory = 4k. 1k represents 1024 memory locations represented as: 1024 = 210. 4k is therefore represented as: 4 × 1024 = 22 × 210 = 212.
