Software Architect - Computer Organization and Architecture - main memory addressing

Example: Memory address from AC000H to C7FFFH; calculate how many address units K

A: K is 1024; (C7FFF + 1-AC000) / 1024 = (C8000-AC000) / 1024 = 1C000 / 1024 = 112

Example: If the address in the memory 112 a word (16bit) addressed constituted by 28 chips. Each 16K chip has a sheet storage unit, the storage unit stores the number of chips per bit

A: (112 * 16) / 28 * 16 * X = 1; X = 4;
