The computer is a 32-bit word length, its storage capacity is 256KB, the word addressed by its addressing range is 64 K
Word addressed by the addressing range is: 0 ~ 64KB.
Calculation step: 256KB = 256 bytes * 1024 * 8,
Computer word by word by 32-bit addressing. The word is 32 bits, the range of (256 * 1024 * 8) / 32 = 64KB
Further, if 32-bit computer word length by half-word addressing. The number of bits of 16-bit half-word, in the range of (2,561,024 * 8) / 16 = 128KB
Refers to the storage capacity of

MAR is

to the number of
memory word
represents the product of the number of bits.
1B = 8bit (bits)
Therefore addressing range = 256KB / 4B = 64K
