Answer “True” or “False” to these questions. If the answer is “False”, you need to provide a reason to state
why the answer is “False” (you will not get points otherwise).
1. Von-Neumman architecture is a stored-program computer. x86 is a Von-Neumann machine. True or
False?
2. Hardware understands the simplified C program generated by the compiler and executes it. True or
False?
3. A integer array ( e.g. , int a[100] in C). The start of the array is at address 0x100. Then the end of the
array is at address 0x140. True or False?
4. The endianness of machine (big endian or little endian) needs to be considered when you want to store
a character (char in C) in memory. True or False?
5. ISA exposes the caches to the programmer. True or False?
6. Program counter (PC) stores the instruction that the hardware is going to execute next. Automatic
increment that occurs to the PC after the instruction has completed execution is the only way to
change it. True of False?
