BICS 1302 - CHAPTER 11 INSTRUCTION SETS

What is the primary function of machine instructions?

• To store data in memory.

• To determine the processor's operation.

• To manage input and output devices.

• To execute software applications.

Which of the following best describes an instruction set?

• A collection of all data types.

• A collection of all instructions a processor can execute.

• A list of memory addresses.

• A set of programming languages.

What does the operation code (Opcode) specify in a machine instruction?

• The location of the next instruction.

• The operation to be performed (e.g., ADD, SUB).

• The input values for the operation.

• The storage location for results.

In a machine instruction, what is the purpose of the source operand reference?

• To specify the operation to be performed.

• To indicate where to store the result.

• To provide the input(s) for the operation.

• To determine the next instruction.

What type of operand is an immediate operand?

• An operand stored in memory.

• An operand value included directly within the instruction.

• An operand that refers to a register.

• An operand that specifies an I/O device.

Which of the following is NOT a type of instruction mentioned in the document?

• Data Processing

• Data Storage

• Data Retrieval

• Control

What is the primary purpose of data movement instructions?

• To perform arithmetic operations.

• To transfer data between memory and external devices.

• To store data in registers.

• To execute control flow operations.

In a zero-address instruction, how are operations performed?

• Using an accumulator.

• Using a stack (LIFO).

• Using direct memory addressing.

• Using multiple registers.

What is the main characteristic of a one-address instruction?

• It uses multiple operands.

• It operates using an accumulator.

• It does not specify any operands.

• It requires two memory references.

Which type of instruction utilizes a temporary register for intermediate values?

• Zero-address instruction

• One-address instruction

• Two-address instruction

• Three-address instruction
