Which is a type of Electrically-Erasable Programmable Read-Only Memory?
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.

In which decade was the telephone invented?
Question 10 Explanation:
Alexander Graham Bell's notebook entry of 10 March 1876 describes his successful experiment with the telephone. Speaking through the instrument to his assistant, Thomas A. Watson, in the next room, Bell utters these famous first words, "Mr. Watson -- come here -- I want to see you".
Who created Pretty Good Privacy (PGP)?
Question 11 Explanation:
Phil Zimmermann created the first version of PGP encryption in 1991. Pretty Good Privacy (PGP) is a data encryption and decryption computer program that provides cryptographic privacy and authentication for data communication. PGP is often used for signing, encrypting and decrypting texts, E-mails, files, directories and whole disk partitions to increase the security of e-mail communications.
What does ECP stand for?
Extended Capabilities Port
Extra Compatible Part
Extended Connection Port
External Cordless Peripheral
Question 12 Explanation:
An Extended Capabilities Port is about 10 times faster than the old standard one, but it is used the same way a regular parallel port is.
How can you catch a computer virus?
Sending e-mail messages
Using a laptop during the winter
Opening e-mail attachments
What is RISC?
Remodeled Interface System Computer
Remote Intranet Secured Connection
Runtime Instruction Set Compiler
Reduced Instruction Set Computer
Question 14 Explanation:

What is the Websites code for the country New Zealand?
What is a NIC?
Netware Intranet Controller
No Internet Connection
Network Interface Card
Network Interference Control

Experts say the healthiest way to view a computer monitor is by_
Placing it 18 to 30 inches away from your eyes
Viewing from a darkened room
Adjusting the screen for maximum contrast
Using special glasses that filter out UV rays
'.BAK' extension refers usually to what kind of file?
MS Encarta document
Which of the following is not a part of the Internet?
World Wide Web
Which of these is a search engine?
What is the Websites code for the country Spain?
The NTSC (National Television Standards Committee) is also used in the country of_?
The first step to getting output from a laser is to excite an active medium. What is this process called?
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.
After the first photons of light are produced, which process is responsible for amplification of the light?
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.
Which of these is a documented hoax virus?
Question 25 Explanation:
A virus hoax is usually an email that gets mailed in chain letter fashion describing some devastating highly unlikely type of virus, you can usually spot a hoax because there's no file attachment, no reference to a third party who can validate the claim and the general 'tone' of the message.
The transformer that develops the high voltage in a home television is commonly called a_?
Van de Graaf
Question 26 Explanation:
The flyback is usually connected to the system that pulls the electron beam across the screen in one direction to 'paint' a line of the image and then returns in the other direction much faster.
What does AM mean?
Question 27 Explanation:
Amplitude modulation was the first type to be used in radio. It works well with HF and morse code.

In which year was MIDI(Musical Instrument Digital Interface) introduced?
What will a UPS be used for in a building?
To provide power to essential equipment
To monitor building electricity use
To carry messages between departments
To control lighting and power systems
Question 32 Explanation:
UPS stands for Uninterruptible Power Supply. Examples of equipment that may require a UPS supply are computers, fire detection systems, hospital operating theatre equipment and escape route lighting.
A coating of dust on a computer's main circuit boards has this probable consequence
Slower hard disk
A given signal's second harmonic is twice the given signal's ..... frequency_?
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.
In what year was the "@"chosen for its use in e-mail addresses?
