• 8 of each

• 10 of each

• 10 32-bit and 6 16-bit registers

• 6 32-bit and 10 16-bit registers

Which of the following is NOT a category of registers in the IA-32 architecture?

• General registers

• Control registers

• Segment registers

• Stack registers

The 32-bit data registers EAX, EBX, ECX, and EDX can be accessed in which of the following ways?

• Only as 32-bit registers

• As 32-bit, 16-bit, and 8-bit registers

• Only as 16-bit registers

In NASM assembly language, how is a macro defined?

• Using macro and endmacro directives

• Using define and enddefine directives

• Using %macro and %endmacro directives

• Using startmacro and stopmacro directives

What is a key difference between macros and subroutines in assembly language?

• Macros are executed at runtime, while subroutines are expanded at assembly time.

• Macros can only be used once, whereas subroutines can be called multiple times.

• Macros are expanded at assembly time, while subroutines are executed at runtime.

• Subroutines cannot accept parameters, but macros can.

In assembly language, what is the primary purpose of the stack segment?

• To store global variables.

• To hold the return addresses of subroutines and handle interrupts.

• To execute arithmetic operations.

• To manage input/output operations.

Which of the following is the correct sequence of stages in the assembly process?

• Syntax Analysis → Lexical Analysis → Opcode Mapping → Machine Code Generation

• Lexical Analysis → Syntax Analysis → Symbol Table Creation → Opcode Mapping → Address Resolution → Relocation and Linking → Machine Code Generation

• Opcode Mapping → Lexical Analysis → Symbol Table Creation → Syntax Analysis → Machine Code Generation

• Symbol Table Creation → Address Resolution → Lexical Analysis → Opcode Mapping → Machine Code Generation

In assembly language, which type of statement is used to allocate memory or define constants?

• Imperative Statements

• Declarative Statements

• Assembler Directives

• Control Statements

What is the primary purpose of relocation in the context of program execution?

• To combine multiple object files into a single executable.

• To assign memory addresses to instructions during assembly.

• To adjust instruction and data addresses when a program is loaded into a memory location different from the one assumed during assembly.

• To convert mnemonics into binary opcodes

Which assembler directive is used to assign a constant value to a symbol?

• START

• END

• EQU

• ORG
