(1 point) Using a diagram/table, please illustrate how the personal record “John Cool, 45, 1980” will be stored in big- and little-endian byte ordering. The personal record includes a name (string), age (integer), and year (integer). The length of a byte is 8, and the length of a word is 32 for the computer.

Solutions

Expert Solution

Solution for the problem is provided below, please comment if any doubts:

The big-endian format:

  • It uses the data stored in the computer in such a manner that the highest significant part of the data will be at lower address.
  • Here the data to be stored is “John Cool, 45, 1980”.
  • The characters will be stored in 8 bit(7-bit ascii and 1 bit parity).
  • The integers are represented using 4 bit hexadecimal numbers.
  • Each word consists of 4 bytes and each byte will be stored as given below.
  • Note: First column is the address of the memory:

ox….0

J

o

h

n

ox….4

C

o

o

0x….8

l

45

19

80

0x….C

The little-endian format:

  • Here the numbers will be stored in such a manner that the lowest significant part will be at lower addressed memory and higher significant part will be at higher addressed memory.
  • Here the data to be stored is “John Cool, 45, 1980”.
  • The characters will be stored in 8 bit(7-bit ascii and 1 bit parity).
  • The integers are represented using 4 bit hexadecimal numbers.
  • Each word consists of 4 bytes and each byte will be stored as given below.
  • Note: First column is the address of the memory:

ox….0
