MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -In the immediate mode, we specify the operand in the instruction itself. Or, in simpler words, instead of an address field, the immediate-mode instruction consists of an operand field.

Detailed explanation-2: -1. In which of these modes, the immediate operand is included in the instruction itself? Explanation: In immediate operand mode, the immediate operand is included in the instruction itself.

Detailed explanation-3: -Immediate Mode − In this mode, the operand is specified in the instruction itself. In other words, an immediate-mode instruction has an operand field instead of an address field. The operand field includes the actual operand to be used in conjunction with the operation determined in the instruction.

Detailed explanation-4: -7) Autoincrement /Autodecrement Mode The register whose number is included in the instruction code, contains the address of the operand. Autoincrement Mode = after operand addressing, the contents of the register is incremented. Decrement Mode = before operand addressing, the contents of the register is decrement.

Detailed explanation-5: -Here are the addressing modes discussed: Immediate: The operand is included in the instruction. Direct: The effective address of the operand in memory is part of the instruction. Indirect: The instruction contains a memory address, which contains the effective address of the operand in memory.
