Given the question: Extract the answer to the question from the following context. Question: What was once found only in large machines?

Multiprocessor and multi-core (multiple CPUs on a single integrated circuit) personal and laptop computers are now widely available, and are being increasingly used in lower-end markets as a result.
The answer is:
