Correct the order of instruction cycle:

A. Read the effective address

B. Fetch the information

C. Execute the instruction

D. Decode the instruction

Choose the correct answer from the options given below:

The correct answer is Option 2: B, D, A, C.

Key Points

• The instruction cycle is the process by which a computer retrieves, decodes, and executes an instruction.
• The correct sequence of operations is:
  • Fetch the information (B): The instruction is fetched from memory.
  • Decode the instruction (D): The fetched instruction is decoded to understand the operation to be performed.
  • Read the effective address (A): The effective address of the data required for the operation is determined.
  • Execute the instruction (C): The instruction is executed and the desired operation is performed.

Additional Information

• The instruction cycle is fundamental to the operation of all computers and involves multiple steps to ensure that the correct operations are performed accurately.
• Each step in the cycle is crucial for the correct execution of instructions, ensuring that the computer processes data efficiently.
• Understanding the instruction cycle is important for those studying computer architecture and assembly language programming.
