Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Software that facilitates the arrangement of information into hierarchies or levels of ideas






2. ~Advantages 1)Share data - increase productivity 2)Share hardware - reduce costs 3)Allow people to work together/communicate ~Disadvantages 1)Easier spread of viruses 2)Privacy issues - especially access levels not set 3)Integrity of data - when shar






3. Grouping of 8 bits






4. Step-by-step procedure for calculating a number






5. To post software= or documents to an online source for availability to others






6. Billions of clock cycles per second - a measurement of a computer's clock speed






7. Device for sending information from the computer (e.g. monitor or printer)






8. Graphics in which images are stored and manipulated as organized collections of pixels rather than as shapes and lines. Contrast with object-oriented graphics.






9. Megabyte; Approximately 1000K or 1 million bytes






10. Random Access Memory; Memory that stores program instructions and data temporarily






11. Software programs that can ask questions - respond to commands - pay attention to users' work patters - serve as a guide and a coach - take on owner's goals - and use reasoning to fabricate their own goals.






12. A standard interface that allows electronic instruments and computers to communicate with each other and work together.






13. Programs that use computer hosts to reproduce themselves. Worm programs travel independently over computer networks - seeking out uninfected workstations to occupy. A form of software sabotage






14. Reference to a specific cell address; doesn't change when copied






15. The illegal duplication of copyrighted software






16. Identifying recurring patterns in input data with the goal of understand or categorizing that input. (Easy for humans) (Ex: fingerprint identification - handwriting recognition - speech recognition - optional character recognition)






17. American Standard Code for Information Interchange; A code that represents characters as 8-bit codes. Allows the binary computer to work with letters - digits and special characters






18. Copy files between storage devices; Repair damaged data files; Guard against viruses; Compress files to take up less disk space; example: defragmenting






19. Optical Mark Reader; A reading device that uses reflected light to determine the location of pencil marks on standardized test answer sheets and similar forms






20. A system of programs that performs a variety of technical operations - providing an additional layer of insulation between the user and the bits-and-bytes world of computer hardware






21. Bit depth; the number of bits devoted to each pixel.






22. Typeface fonts in which the characters are embellished with fine lines (serifs) at the ends of the main strokes






23. A program that eliminates fragmented files by changing the assignment of clusters to files; Easier to find files/programs -> Faster computer






24. Software that serves as tools for doing system maintenance and some repairs that are not automatically handled by the operating system;






25. 1) ability to create models with physical characteristics (weight and volume); 2) model can be rotated; 3) can evaluate structural performance by applying an imaginary force; 4) designs can be easily altered and edited






26. Uninterruptable Power Supply; A hardware device that protects computers from data loss during power failures






27. All type - including roman - bold - and italics - of a single design (i.e. Helvetica)
