What is immediate addressing in assembly language?

• Immediate addressing is a method of addressing in assembly language where the operand is calculated at runtime.

• Immediate addressing is a method of addressing in assembly language where the operand is specified using a register.

• Immediate addressing is a method of addressing in assembly language where the operand is specified within the instruction itself.

• Immediate addressing is a method of addressing in assembly language where the operand is stored in a separate memory location.

What is direct addressing in assembly language?

• Direct addressing refers to accessing memory locations indirectly using the address specified in the instruction.

• Direct addressing involves accessing memory locations using a pointer to the address.

• Direct addressing is a method of accessing memory locations by using a register to hold the address.

• Direct addressing in assembly language refers to accessing memory locations directly using the address specified in the instruction.
