Memory Address Data 01 02 03 11001100 00001000 11101011 00110101 Write the binary Word in Big Endian format. Answer: a) b) Write the binary Word in Little Endian format. Answer:

Explanation / Answer

12 . a)

In big Endian format the most significant bits of the data word will be stored in lowest memory address.

If the given representaion is in big endian format Then binary word is : 11001100 00001000 11101011 00110101

b) In little Endian format the LSB bits of the given dataword will be stored in lowest memory address

If the given representaion is in little endian format Then binary word is : 00110101 11101011 00001000 11001100
