A particular model of a personal computer indicate in the owners manual that the following memory locations are used for storage of operating system sub-routines, 07A2B to 0AD68 Hex inclusive and 02D8 TO 03E00 Hex inclusive. Determine the total number of memory locations used for this purpose in hexadecimal.
Homework Answers
First convert the hexadecimal number into decimal form then
calculate the no. of memory location then convert then result into
hexadecimal.
