hidden or inaccessible place.
Physical Memory - Correct Answers -how much RAM you have installed in your
computer.
Virtual Memory - Correct Answers -memory that appears to exist as main storage
although most of it is supported by data held in secondary storage, transfer between the
two being made automatically as required.
Hyperthreading - Correct Answers -Intel's proprietary simultaneous multithreading
(SMT) implementation used to improve parallelization of computations
Clock Speed - Correct Answers -the number of pulses per second generated by an
oscillator that sets the tempo for the processor
Moore's Law - Correct Answers -the number of transistors per square inch on integrated
circuits had doubled every year since their invention and will continue to do so
User Interface - Correct Answers -the means by which the user and a computer system
interact, in particular the use of input devices and software.
CAPTCHA - Correct Answers -the security things that tell you to type what you see to
