Final answer:
The three general steps in the LC3 instruction cycle are fetch, decode, and execute.
Step-by-step explanation:
The LC3, or Little Computer 3, is a simplified computer architecture used for educational purposes. The LC3 instruction cycle consists of three general steps: fetch, decode, and execute. In the fetch step, the LC3 fetches the instruction from memory. In the decode step, the instruction is decoded to determine the operation to be performed.
