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. A method of optical storage for digital data that has greater storage capacity than compact discs.






2. The radio waves or cable that transport data on a network.






3. Software that facilitates the communication between a device and the operating system.






4. A type of wireless technology that uses radio waves to transmit data over short distances. Often used to connect peripherals such as printers and keyboards to computers or headsets to cell phones.






5. 'An electronic filing system best used for larger and more complicated groups of data that require more than one table and the ability to group - sort - and retrieve data and generate reports.'






6. The application of computer systems and techniques to gather potential legal evidence; a law enforcement specialty used to fight high-tech crime.






7. A type of computing that relates to emotion or deliberately tries to influence emotion.






8. Eight binary digits(bits)






9. An internal hard drive that is enclosed in a protective case to make it portable - the drive is connected to the computer with a data transfer cable and is often used to back up data.






10. 'A section of a hard drive platter - wedge-shaped from the center of the platter to the edge.'






11. The 802.11 standard for wireless data transmissions established by the Institute of Electrical and Electronics Engineers (IEEE).






12. Software that provides street maps and written directions to locations.






13. A network in which the nodes are located within a small geographic area.






14. A computing device that runs a full-featured operating system but weighs two punds or less.






15. The most commonly used wired Ethernet standard deployed in devices designed for home networks which provides bandwidth of up to 1 Gbps.






16. Being familiar enough with computers that you understand their capabilities and limitations and know how to use them.






17. Anyone who unlawfully breaks into a computer system (whether an individual computer or a network).






18. 'Program code made publicly available for free; it can be copied - distributed - or changed without the stringent copyright protections of proprietary software products.'






19. A server that manages all client-requested printing jobs for all printers on the network.






20. 'The portion of a company's intranet that is used to share business information with business partners such as vendors - suppliers - and customers.'






21. 'A wireless standard established in 1997 by the Institute of Electrical and Electronics Engineers; also known as WiFi (short for Wireless Fidelity) - it enables wireless network devices to work seamlessly with other networks and devices.'






22. A small circuit board that holds a series of random access memory (RAM) chips.






23. A hardware device that uses lasers or light to read from - and maybe even write to - CDs - DVDs - or Blu-ray discs.






24. 'A device on a network such as a router - hub - and switch that moves data signals around the network.'






25. A set of memory chips - located on the motherboard - which stores data and instructions that cannot be changed or erased; it holds all the instructions the computer needs to start up.






26. A special shelf inside a computer case that is designed to hold storage devices.






27. 'In a wireless network - a device that translates the electronic data that needs to be sent along the network into radio waves and then broadcasts these radio waves to other network nodes.'






28. 'The mechanism that retrieves (reads) and records (writes) the magnetic data to and from a data disk. They move from the outer edge of the spinning platters to the center - up to 50 times per second.'






29. A special numerical code that prioritizes requests from various devices. These requests then are placed in the interrupt table in the computer's primary memory.






30. A unit of computer storage equal to approximately one thousand bytes.






31. A temporary storage area on the hard drive where the operating system 'swaps out' or moves the data or instructions from random access memory (RAM) that have not recently been used. This process takes place when more RAM space is needed.






32. A drive that uses the same kind if memory that flash drives use - but can reach data in only a tenth of the time a flash drive requires.






33. A port that is slightly larger than a standard phone jack and transfers data at speeds of up to 10 -000Mbps; used to connect a computer to a DSL or cable modem or a network.






34. A program for editing digital video.






35. A program or hardware mechanism that controls which computer is allowed to use the transmission media in a network at a certain time.






36. 'Permanent storage - as in read-only memory (ROM).'






37. System software that controls hardware devices.






38. A specially designed computer that can perform comples calculations extremely rapidly; used in situations in which complex models requiring intensive mathmatical calcualtions are needed (such as weather forecasting or atomic energy research).






39. A measure of the difference in light intensity between the brightest white and the darkest black colors that a monitor can produce. If the contrast ratio is too low - colors tend to fade when the brightness is adjusted to a high or low setting.






40. 'A mini-application that runs on the desktop - offering easy access to a frequently used tool such as weather or a calendar item.'






41. A specialized computing device designed to store and manage network data.






42. Software that translates spoken words into typed text.






43. 'Programs used to create and edit written documents such as papers - letters - and r






44. 'A type of hard drive that uses much thinner cables - and can transfer data more quickly - than IDE drives.'






45. The language computers use to process data into information - consisting of only the values 0 and 1.






46. 'A group of two or more computers (or nodes) that are configured to share information and resources such as printers - files - and databases.'






47. A port that uses a traditional telephone signal to connect a computer to the internet.






48. A device that absorbs a signal so that it is not reflected back onto parts of the network that have already received it.






49. A device that holds all permanently stored programs and data; can be located inside the system unit or attached to the system unit via a USB port.






50. A group of icons collected for easy access.
