Computer Scavenger Hunt

1. What does DVD stand for? Digital versalisatie disk
How many dvd formants are availbale? Their are 6 dvd formants dvd video, dvd- ron,dvd-r,dvd-ram,dvd-rw,dvd-audio.
2.What is a digbat?Special characters like stars, hands, arrows, and geometric shapes you can use to decorate a document. A collection of dingbats is found in a popular font called Wingdings.

3.What is a handshake?Two modems perform a handshake each time they meet, just as two people shake hands to greet each other. If the modem speaker is on, you can actually hear the handshake — it’s that annoying series of squeals and signals. The handshake helps the modems determine how they will exchange information.

4.What is a homepage?An introductory screen on the World Wide Web, used to welcome visitors. A home page can include special underlined text or graphics you click on to jump to related information on other pages on the Web. Many individuals, businesses, and organizations now have home pages on the World Wide Web. See also WORLD WIDE WEB.

5.What handles can you not hold in your hand.Little squares at the edges and corners of a selected graphic on your screen. You can move a handle with your mouse pointer to resize or reshape the graphic.

6.What is ENICA? ENICA is a Electronic Numerical Integrator Analyzer and Computer), the gigantic machine credited with starting the modern computer age.
7. What contribution did Ada Byron make to computing?When she showed Babbage her translation he suggested that she add her own notes, which turned out to be three times the length of the original article. Letters between Babbage and Ada flew back and forth filled with fact and fantasy. In her article, published in 1843, Lady Lovelace's prescient comments included her predictions that such a machine might be used to compose complex music, to produce graphics, and would be used for both practical and scientific use. She was correct. 8.What kind of wafers are used at Intel to make computer chips?Computer chip technology is in all sorts of everyday items, from space shuttles to coffee makers, traffic lights, and computers. A basic rule of thumb is, if a device uses electricity and you can "tell it what to do" by programming it or customizing it, there's a chip inside.
9. What do they call the suit that cleanroom technicians must wear while making computer chips?Computer chip technology is in all sorts of everyday items, from space shuttles to coffee makers, traffic lights, and computers. A basic rule of thumb is, if a device uses electricity and you can "tell it what to do" by programming it or customizing it, there's a chip inside.
10. What does modem stand for anyway?A modem is a device or program that enables a computer to transmit data over, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms.
11.What is a bit? A bit (short for binary digit) is the smallest unit of data in a computer.
How many bits are in a byte?A bit has a single binary value, either 0 or 1.
How many nibbles are in a byte? Half a byte (four bits) is called a nibble.
12. The ARPANET 's development began in 1966. It was an experiment to connect universities so they could
share information. What do we call this today? Today we call it email.
13. In what year was the first World-Wide Web software created by Tim Berners-Lee?Hobbes' Internet Timeline Copyright (c)1993-2006 by Robert H Zakon. Permission is granted for use of this document in whole or in part for non-commercial purposes as long as this Copyright notice and a link to this document, at the archive listed at the end, is included.

Links to this document are welcome after e-mailing the author with the document URL where the link will appear. As the Timeline is frequently updated, copies to other locations on the Internet are not permitted. 14. Project Gutenberg puts on the Internet public domain literature and information.Project Gutenberg began in 1971 when Michael Hart was given an operator's account with $100,000,000 of computer time in it by the operators of the Xerox Sigma V mainframe at the Materials Research Lab at the University of Illinois.
What was the first document posted?
15. When were floppy disks introduced?In 1970 the eight inch floppy disk drive was introduced by IBM.
16. How many megabytes of data can a factory made audio CD hold?When you copy data to a CD, you must take care that the your data does not exceed the capacity of the CD you are recording to. Due to the audio origin of CDs, the amount of information a CD can hold is measured in minutes:seconds:sectors. Each second contains 75 sectors, each of which can hold 2048 bytes (2 kilobytes) of Mode 1 user data. Recordable CDs come in 21- (80 mm diameter), 63-, and 74-minute sizes (both 120 mm diameter)
Factory-recorded CDs can hold up to 74 minutes of data.
17. Douglas Engelbart was a computer visionary of the 1960's. What did he invent that you find handy?At SRI, Engelbart earned a dozen patents in two years, working on magnetic computer components, fundamental digital-device phenomena, and miniaturization scaling potential
18. What do the letters CD-ROM stand for?Compact Disc-Read Only Memory. A standard for compact disc to be used as digital memory media for personal computers. The specifications for CD-ROM were first defined in the Yellow Book.
19. Name three computer peripherals.Any external device that plugs into your computer, such as a printer, modem, scanner, or tape drive.Any external device that plugs into your computer, such as a printer, modem, scanner, or tape drive.
20. What does GUI (pronounced "goo-ey") mean?A GUI (usually pronounced GOO-ee) is a graphical (rather than purely textual) user interface to a computer.
21 What is an advantage of the Dvorak keyboard?The Dvorak keyboard layout is a control panel option on almost every current computer. It is a vastly more comfortable and efficient alternative to the standard "QWERTY" pattern, which was designed in the 1800s with no effective attempt at typing comfort.
22. What is a computer virus?A computer virus is a program designed to spread itself by first infecting
executable files or the system areas of hard and floppy disks and then
making copies of itself. Viruses usually operate without the knowledge or
desire of the computer user.
23. How did Marcian Hoff's invention change computers? Chernoff submitted his idea and made it through several rounds of competition, continually improving his design with each round. In the end, Staples chose his Rubber Bandits from among more than 8,000 entries; they awarded Chernoff $5,000 and signed him to an exclusive two-year agreement. In 2005, the company began selling the colorful bands in retail stores across the country. The bands were sold through late 2007.
24. Apple Computer's G4 is a supercomputer because its operations can be measured in gigaflops. What is a
gigaflop? A gigaflop is a measure of computing speed equal to one billion floating-point operations per second.
25. What mammal, other than humans, uses a computer?At Sea Life Park Hawaii, Earthtrust researchers set up custom underwater touch screens connected to Power Macintosh computers. Dolphins interact with the touch screens by interrupting a grid of infrared rays with their rostrums — what most of us would call their noses. Dolphins at the park are free to use the computers at their own behest, and they apparently find it quite entertaining.
