Question 3
Which is a type of Electrically-Erasable Programmable Read-Only Memory?
A
Flash
B
Flange
C
Fury
D
FRAM
Question 3 Explanation: 
It's commonly used for MP3 players, computer BIOS code and "thumb"drives. Originally developed in Japan by Toshiba, it has become quite popular for products requiring non-volatile erasable memory. Flash devices have a limited number of erase cycles (typically 10, 000 to 1, 000, 000 cycles) so they're not as good a choice for applications in which the data changes constantly. However, since it has no moving parts (unlike a hard disk) it is an excellent choice for storing the operating code for small personal electronics like PDAs, cell phones, digital cameras, and the data in items like MP3 players.

Question 23
The first step to getting output from a laser is to excite an active medium. What is this process called?
A
Pumping
B
Exciting
C
Priming
D
Raising
Question 23 Explanation: 
A collection of atoms or molecules that can be excited to a higher energy state is called an active medium. Before lasing can occur, the active media is "pumped". The process of raising the atoms in the active media from a lower energy state to a higher state is like pumping water up from a well.






Question 24
After the first photons of light are produced, which process is responsible for amplification of the light?
A
Blackbody radiation
B
Stimulated emission
C
Planck's radiation
D
Einstein oscillation
Question 24 Explanation: 
The word "laser"is actually an acronym for light amplification by stimulated emission of radiation. Atoms or molecules of the active medium that have been excited to a higher energy level are stimulated by a passing photon to relax to a lower energy level and emit a photon that is indistinguishable from the passing photon, thereby increasing the number of photons like the incident one.

Question 34
A given signal's second harmonic is twice the given signal's ..... frequency_?
A
Fourier
B
Foundation
C
Fundamental
D
Field
Question 34 Explanation: 
A given signal's second harmonic is twice the given signal's fundamental frequency. Harmonics are generated when there are non-linearities in an amplifier (there are always non-linearities). The worse the non-linearities, the more harmonics. A signal at 27.5 MHz (approximate frequency for US citizen's band) would have a second harmonic at 55.0 MHz (on US channel 2!). Can you see why there might be problems? A CB operator might do well to place a low-pass filter on his radio.
