Detailed explanation-1: -Since we have 24-bit addresses and address resolution is at the byte level, 224 bytes can be addressed. Then, words are there in address space = 2 24 2 4 = 220 = 1M words can be addressed. Hence the correct answer is 1 M words.
Detailed explanation-2: -In computing, a memory address is a reference to a specific memory location used at various levels by software and hardware. Memory addresses are fixed-length sequences of digits conventionally displayed and manipulated as unsigned integers.
Detailed explanation-3: -Big-endian is an order in which the “big end” (most significant value in the sequence) is stored first, at the lowest storage address. Little-endian is an order in which the “little end” (least significant value in the sequence) is stored first.
Detailed explanation-4: -Big-endianness is the dominant ordering in networking protocols, such as in the internet protocol suite, where it is referred to as network order, transmitting the most significant byte first.
