Question

Which technology is used in the processor of a computer to simulates a single processor into two virtual processors to the operating system?

• A. Hyper threading technology
• B. Multi core technology
• C. Simulation technology
• D. Multi threading technology

Answer 1

Answer:

A. Hyper threading technology

The technology is Hyper-Threading Technology (HTT) (or generally known as Simultaneous Multithreading / SMT).

• Hyper-Threading (Intel) duplicate parts of the processor core—specifically the architectural state (registers, program counters)—while sharing the actual execution engines, caches, and system bus.

• To the operating system (OS), a single physical CPU core with Hyper-Threading enabled appears as two logical (virtual) processors.

• This allows the OS thread scheduler to assign two separate threads or processes to execute simultaneously on a single physical core, reducing idle hardware time and improving overall processing efficiency
