According to von Neumann's design, which the following is not one of the four basic components of a computer? Hared Dick Out put Input primary Memory Central Processing Unit AC++ function with the declaration char f (int x, int y) has no local variables. How many bytes would be added to a run-time stack in order to accomplish a call to this function (including related allocations by the caller, hardware, and f)? a) 4 b) 5 c) 6 d) 7 e) 8 When a subroutine is called on a Pep/8 computer (using the CALL instruction what value is loaded into the Program Counter? a) the address of the subroutine's first instruction b) the value zero c) the address of the top of the stack do a value that is loaded from the stack a) e) a value that is copied from the Accumulator. Which of the following is equal to^111, ?^7_10^21_10^57_10^73_10^100_10 Assuming the value -42 (negative 42) is stored in 8-bit 2's complement format, which of the following Hex values represents the bits that will be stored? a) a) AA b) A5 c) C5 d) C6 e) D6 Assuming the value 23.3125 is stored in the 16-bit floating point number representation that used in homework (a zero bit means positive, there are five exponent bits store an exponent, and there are ten significant mantissa bits), which of the following values represents the bits that will be stored? a) B5CC b) 7A6A. c) D722. d) 3345 e) 4DD4 How many values can be represented by a sign-magnitude integer with 8 bits? unique a) 16 b) 255 c) 256 d) 512 e) 513 If the instruction fetched on a Pep/8 computer, what value goes into the operand E10A43 is portion of the Instruction register? a) El b) 0A c) 43 d) E10A. e) 0A43 If the Peps machine was enhanced to allow 500 operation-codes, which register would need to be made larger than it currently is?
