The operand is a computed value derived from other instructions.

The operand is a register that holds a value.

In immediate addressing mode, the operand is a constant value embedded in the instruction.

The operand is a memory address that points to a variable.

Direct addressing mode requires an immediate value instead of a memory address.

Direct addressing mode allows for indirect access to memory locations.

Direct addressing mode uses a register to hold the operand.

Direct addressing mode in the 8086 specifies the exact memory address of the operand directly in the instruction.

Register addressing uses CPU registers for operands, while memory addressing accesses data in main memory.

Register addressing is faster than memory addressing.

Memory addressing uses CPU registers for operands.

Register addressing accesses data in main memory.

The stack addressing mode uses the instruction pointer (IP) for data access.

The stack addressing mode is only used for arithmetic operations.

The stack addressing mode directly accesses memory without using registers.

The stack addressing mode uses the stack segment (SS) and stack pointer (SP) to access data, enabling push and pop operations.
