Final answer:

Hyper-Threading Technology makes one core appear to operate as two or more in Intel CPUs.

Step-by-step explanation:

The microarchitecture that makes one core appear to operate as two or more in Intel central processing units (CPU) is called Hyper-Threading Technology. It was first introduced by Intel in 2002 and has been implemented in various generations of Intel processors since then. Hyper-Threading Technology allows a single physical core to handle multiple software threads simultaneously, improving overall performance and multitasking capabilities.

For example, in a processor with 4 physical cores and Hyper-Threading support, the operating system and applications can see 8 logical cores, allowing for better resource utilization and increased efficiency.

It's important to note that while Hyper-Threading Technology improves performance in certain scenarios, the actual benefits depend on the specific workload and applications being used.
