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. Communications activity. Handled by NSFnet.






2. Dozens or hundreds of thin strands of glass or plastic that use light to transmit signal. Carries more signals - faster - less noise - better security - smaller size






3. A communications device that can convert digital signals to analog signals and analog signals to digital signals so data can travel along an analog telephone line. In the form of an adapter card you insert in an expansion slot on motherboard.






4. Consists of special purpose chip and electronic circuits that control the transfer of data - instructions - and information from a disk to and from the system bus and other parts of the computer.






5. Provides a means of sharing distributing and searching through documents by converting them unti a format that can be viewed by any user.






6. Extends the capabilites of a browser.






7. A cable forms a closed loop with all computers. one direction






8. Method that uses multiple processors to execute a single program or task requires special software that recognizes how to divide the problemand bring results back together






9. A digital code attached to an electronic message or document - which is unique and which can be used to authenticate the sender or owner. Most often used in electronic commerce.






10. Anopening inside the system unit in which you can install additional equipment. Different than a slot






11. Magnetoresistive ram- stores data using magnetic charges not electrical. Retains contents after power is out






12. Small capacity built directly in the processor chip






13. Processor begins to fetch a second instruction before it completes the full machine cycle






14. Uses email as a vehicle for extortion. Threaten users if they are not paid a sum of money






15. A storage device that typically uses flash memory to store data instructions and information. Faster - use less power - last more than 5 years - higher failure rate - cost much more






16. Device that connects to the system unit and is controlled by the processor in the computer. (modem - disk drives - printers)






17. Human speech is bc of its continous signal that vary in strength and quality






18. Uses devices that emit and sense light to detect the mouses movement






19. A computer with limited processing power that enables users to send data to and recieve info from a host computer. POS terminals - ATM - and DVD kiosks






20. A number that uniquely identifies each computer or device connected to the internet (0-255)






21. Hypertext transfer protocol






22. Shrinks file sizes - lossy-you will be able to restore the file to its exact original state - lossless - compressed file can be returned to its original state






23. Consists of capturing - sorting - analyzing - displaying - printing - and manipulating images.






24. Copies itself repeatedly in memory using up system resources and possibly shutting down the system






25. System board- is the main circuit board of the system unit.






26. Same intent as cracker but does not have technical skills and knowledge. Often use prewritten hacking






27. Computing device small enough to hold in your hand






28. Slightly slower than L1 cache but has higher capacity. (advanced transfer cache)






29. Copyrighted software provided at no cost by company that retains all rights to software






30. Consists of one or more twisted pair wires bundled together - Used for transmission media. Wires are twisted to reduce the noise






31. Sends digital data and info from a comp to a DSL line






32. Someone who uses internet to destroy or damage computers for political reasons.






33. zombie






34. Characteristics include capacity - platters - read/write heads - cylinders - sectors and tracks - rpm - transfer rate - and access time






35. Faster - higher quality than ink jet. Uses toner that sticks to the page from a combo of pressure and heat.






36. A rectangular opeining that typically holds disk drives.






37. A colection of individual programs available together as a unit. lower cost and ease of use






38. A collection of data organized in a manner that allows access retrieval and use of that data






39. Connects the processor to cache.






40. Saves any open documents and programs to RAM and places computer into a low power state






41. Case of the system unit to protect internal damage






42. Other computers and mobile devices on the networ that rely on the server for its resources






43. Controls access to hardware - software - and other resources on the network and provides a central storage area for programs - data - and info.






44. Central processing unit- processor- interprets and carries out the basic instructions that operate the computer.






45. Programs that control or maintian the operations of the computer and its devices. Interface between user - application software - and computers software
