Question

What is the maximum memory address space that the processor can access directly if it is connected to a word (16 bits) addressable memory?

Answer 1

Answer:

The signed range of integer values that can be stored in 16 bits is −32,768 (−1 × 215) through 32,767 (215 − 1); the unsigned range is 0 through 65,535 (216 − 1). Since 216 is 65,536, a processor with 16-bit memory addresses can directly access 64 KB (65,536 bytes) of byte-addressable memory.
