Ch 01: Introduction to Assembly Language

In 8088 CPU architecture, which register is bitwise significant, meaning each individual bit serves an independent status or control flag function?

When two 16-bit numbers are added, the sum can be up to 17 bits long. In which CPU status flag is this extra carry bit stored so it can be tested?

add ax, bx  ; Carry out of bit 15 enters CF

True or False: A computer program is defined as an ordered sequence of instructions executed by the processor.

True or False: In Intel x86 assembly language syntax, instructions follow the format 'instruction destination, source'.

mov ax, bx  ; AX is destination, BX is source

What operation is performed by the assembly instruction 'ADD AX, BX'?

add ax, bx

Consider the following assembly code segment: [org 0x0100] mov ax, [num1]; load first number in ax mov bx, [num2]; load second number in bx add ax, bx What is the correct inline comment for line 4 ('add ax, bx')?

add ax, bx

In 16-bit division using the 'DIV reg16' instruction, a 32-bit dividend held in register pair DX:AX is divided by a ________ operand, storing the quotient in AX and remainder in DX.

div bx  ; Divides 32-bit DX:AX by 16-bit BX

In 8088 assembly language, division performed by the ________ instruction is strictly integer division, returning an integer quotient and remainder while discarding fractional values.

The ________ instruction performs unsigned binary multiplication of a source operand with the accumulator register.

mul bx  ; AX * BX -> DX:AX

True or False: The address bus is unidirectional, and memory addresses always travel strictly from the processor to memory.
