Ch 01: Introduction to Assembly Language

There is a central register in every processor called the ________, and the word size of a processor is defined by the width of its ________.

Which group of instructions allows changing specific processor behaviors and flag states (e.g., interrupt state, direction flag)?

The iAPX88 (8088) architecture consists of how many total programmer-accessible 16-bit registers?

In the 8088 CPU architecture, the letter 'B' in register BX stands for ________ due to its primary role in memory addressing.

mov ax, [bx]  ; Base register addressing

In Intel iAPX88 architecture, which special-purpose register contains the memory offset address of the next instruction to be executed?

In 8088 CPU architecture, which register is bitwise significant, where each individual bit functions as an independent status or control flag?

When two 16-bit numbers are added, the sum can be up to 17 bits long. Where is this extra 17th 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 for the processor.

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

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

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 int 0x21 num1: dw 5 num2: dw 10 What is the correct inline comment for line 4 ('add ax, bx')?

add ax, bx
