Q. Combined two processors, their caches and cache controllers on to a single integrated circuit

A
Hyperthreading technology
B
Dual Core technology
C
Multi-core technology
D
Laser Technology
Solution:

Hyper-threading is Intel’s proprietary simultaneous multithreading implementation used to improve parallelization of computations performed on x86 microprocessors. It first appeared in February 2002 on Xeon server processors and in November 2002 on Pentium 4 desktop CPUs.

Dual-core refers to a CPU that includes two complete execution cores per physical processor. It has combined two processors and their caches and cache controllers onto a single integrated circuit (silicon chip).

In consumer technologies, multi-core is usually the term used to describe two or more CPUs working together on the same chip. Also called multicore technology, it is a type of architecture where a single physical processor contains the core logic of two or more processors.
