Which of the following is/are correct?

  1. Little-endian versus big-endian comes into play when the memory is word-addressable and an integer sits completely in one byte.
  2. Little-endian versus big-endian comes into play when the memory is byte-addressable and an integer spans multiple bytes.
  3. The issue of which "endian" type(big or little) the computer uses becomes critical when the memory assigns a separate address to each byte.
  4. The issue of which "endian" type(big or little) the computer uses becomes critical when the memory assigns a separate address to each word.

Byte addresses can be assigned across words in two ways :

Big-endian and little-endian.

Big Endian: the most significant byte has the lowest address, and the least significant byte has the highest address $(1-2-3-4).$

Little Endian: the least significant byte has the lowest address, and the most significant byte has the highest address $(4-3-2-1).$
