Answer: A - You would recommend Multi-Threading to this user, which allows a single CPU to simulate multi-CPU technology, processing two separate sets of instructions.
Key Takeaway - In Multi-Threading, the operating system sees two virtual CPUs, even though only one is present. A multicore processor physically contains two or more actual processor cores in one CPU. Hypertransport is an AMD technology unrelated to Multi-Threading, and 64-bit refers to a type of CPU architecture, the other type being 32-bit.
