On what date was the debut of the first IBM Personal Computer? |
| Answer» Before IBM created its personal computer, two types of computer systems, Apple II and CP-M, dominated the microcomputer world. Neither of these systems were PC compatible, or Mac-compatible (the two primary standards in place today). The original IBM PC became a new standard in the microcomputer industry. Since then, hundreds of millions of PC-compatible systems have been sold, as the original PC grew into a large family of computers and peripherals. More software has been written for this computer family than for any other system on the market. | |

The invention of the transistor, or semiconductor, was one of the most important developments leading to the personal computer revolution. What company invented the transistor in 1947? |
| Answer» The transistor, which essentially is a solid-state electronic switch, replaced the much less suitable vacuum tube. Because the transistor consumed significantly less power, a computer system built with transistors was much smaller, faster and more efficient than a computer system built with vacuum tubes. | |

| 14. |
Which Intel chip was the first to support a 32-bit bus architecture? |
| Answer» The 386 chip was the first to offer a possible 32- or 64-bit access to data. OS-2 2.x or higher and Windows 95 required at least a 386 CPU while Windows NT 4.x required at least a 486 CPU to run. | |
| 15. |
What is RISC? |
| Answer» Reduced Instruction Set Computer - a type of microprocessor that relies on simple instructions which can be used to build more complicated ones. | |

| Answer» A new type of disc developed by Constellation 3D Inc. These discs can hold up to to 140 GB of data. | |
| 17. |
Which of these is a documented hoax virus? |
| Answer» 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. | |
| 18. |
What does SSL stand for? |
| Answer» A protocol developed by Netscape to allow secure connections over the net. | |
| 19. |
What is a URL? |
| Answer» URL stands for Uniform Resource Locator. It is an address for a specific document found on the Web. | |
| 20. |
What is a NIC? |
| Answer» A NIC is a Network Interface Card. Usually a card that is plugged into a computer's expansion slot. | |
| 21. |
http://www.indiabix.com - is an example of what? |
| Answer» A URL (Uniform {or Universal} Resource Locator) is an address for a specific document found on the Web. It is made up of several components: a domain name, the directories and subdirectories of the site, and the extension. To learn about these parts of a URL, visit the Evaluating Web Sites tutorial. | |
| 22. |
What are the three main search expressions, or operators, recognized by Boolean logic? |
| Answer» The three most commonly used Boolean operators are: AND, OR, and NOT. On the Web, Boolean operators are used in advanced searches to combine search items. For example, an "AND" operator between two words ("football AND television") tells the search engine to find documents that contain both of these words. | |
| 23. |
How many diodes are in a full wave bridge rectifier? |
| Answer» Device used to convert AC to DC voltage. | |
| 24. |
The input used by an antenna or cable to a TV set uses frequencies called...? |

| 25. |
What was the active medium used in the first working laser ever constructed? |
| Answer» Theodore Maiman built the first working laser using a ruby rod while working at Hughes Research Laboratories in Malibu, California. It lased for the first time on May 16, 1960. | |
| 26. |
In which decade was the ARRL founded? |
| Answer» On April 6, 1914, Hiram Percy Maxim proposed the formation of the American Radio Relay League. | |
| 27. |
What does EPROM stand for? |
| Answer» A chip found in alomst every microprocessor... | |
| 28. |
Once the active medium is excited, the first photons of light are produced by which physical process? |
| Answer» Spontaneous emission is what you see with most "glow in the dark" toys. You excite the toy by exposing it to bright light, then the toy glows in the dark by spontaneously emitting photons as the excited atoms relax back down to their normal state. | |
| 29. |
"FET" is a type of transistor, Its full name is ________ Effect Transistor...? |
| Answer» The terminals of FETs are called gate, drain and source. You might be more familiar with bipolar junction transistors (BJTs), which have terminals called base, collector and emitter. FETs were conceptualized first, but BJTs were easier to produce and so developed sooner. | |
| 30. |
What does AM mean? |
| Answer» Amplitude modulation was the first type to be used in radio. It works well with HF and morse code. | |
| 31. |
Which consists of two plates separated by a dielectric and can store a charge? |
| Answer» Useful in tuning and filtering circuits, it blocks DC while passing AC. How much charge a capacitor can store is its capacitance, measured in farads.nn | |
| 32. |
Sometimes computers and cache registers in a foodmart are connected to a UPS system. What does UPS mean? |
| Answer» An uninterruptable power supply (UPS) is a backup power supply, such as a battery, that provides emergency power in the event that power is lost from the main supply. | |
| 33. |
After the first photons of light are produced, which process is responsible for amplification of the light? |
| Answer» 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. | |
| 34. |
Which is NOT an acceptable method of distributing small power outlets throughout an open plan office area? |
| Answer» Extension cords can be a tripping hazard, and can be easily damaged, causing an unsafe situation. There are many ways of safely getting power to each work place, where wiring is protected and concealed. | |
| 35. |
Which motor is NOT suitable for use as a DC machine? |
| Answer» The squirrel cage motor is the only one without any connection to the armature. | |
| 36. |
A given signal's second harmonic is twice the given signal's __________ frequency...? |
| Answer» 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. | |
