Which Intel technology is designed as a single CPU, but appears to the operating system as two separate processors?
A) Dual-core
B) Caching
C) Hyper-threading
D) SpeedStep
The answer: C) Hyper-threading
Intel introduced hyper-threading in the Pentium 4 processor, and found around a 30% speed improvement over non-hyper-threaded processors of similar speeds.
The incorrect answers:
A) Dual-core
Dual-core processors actually have multiple CPU “cores” inside of a single CPU package, each working as independent CPUs.
B) Caching
A CPU cache is fast memory that sits on and/or near the CPU to increase the speed of requests. Multiple requests for the same information can be retrieved from fast cache memory instead of slower system RAM.
D) SpeedStep
Intel’s SpeedStep technology is used in portable systems to slow down the CPU when the computer gets too hot.
