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. Screen savors were made to prevent this - which etched images permanently onto the screen






2. 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.






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






4. Serves as the interface between the user - the app software - and the computers hardware






5. Does not require a newsreader - easier to use than a newsgroup






6. Has the illusion of moving images becuase it sends a continuos stream of images






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






8. A unique number that identifies the location of a byte in memory






9. A motion sensing mouse - allows you to control objects by moving the mouse in predetermined directions through air






10. 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






11. Graphic file (JPEG - GIF) slowly replacing GIF






12. Continues to operate when one of its components fails - ensuring that no data is lost






13. Complementary metal oxide semiconductor provides high speeds and consumes little power. Used by RAM - flash memory - and other memory chips. USes battery power






14. Integrates the functions of a processor - memory and a video card on a single chip.






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






16. Company that provides wireless internet access to computers

18. All computers connected to central device. Hub or switch






19. The amount of data - instructions - and information that can travel over communications channel






20. The use of computer or network with out permission






21. Combines several GIF images ina single GIF file.






22. Communications device that connects multiple computers or other routers together and transmits data to its correct destination on a network






23. Allows users to keep typing without using enter at the end of each line






24. The layout of the computers and devices ina cmonnunications network. Star - bus - ring.






25. Mad ef aluminum - glass - or ceramic and is coated with an alloy material that allows material to be recorded magnetically

29. Smallest element in an electronic image






30. Computer automatically can configure adapter cards and other peripherals as you install them






31. The operating system interrupts a program that is executing and passes control to another program waiting to be executed. Operating system regains control if one program stops operating properly






32. The time it takes a signal to trvale from one location to another on a network Neg effect- distance - type of transmission media - and number of nodes data must travel through - bandwith high latency low for best performance






33. The process of using the operating system to restart a computer. Properly closes programs but doesnt save work






34. Organization that sells and manages domain names






35. The number of bytes a storage medium can hold






36. Internet teephony- enables users to speak to other users over the internet






37. A document that you return to the company that creates and sends it.






38. Can be peropheral or chip - creates sound from digital instructions.






39. Consists of electronic components that store instrcuctions waiting to be executed by the processor - data needed by those instructions - and the results of processing data. Consist of one or more chips on the motherboard or some other circuit board o






40. Electronic data interchange which defines how data transmits across telephone lines or other means. Minimal peperwork for businesses






41. The process of dividing the disk into tracks and sectors






42. The standard that outlines characteristics of how two network devices communicate






43. A rectangular opeining that typically holds disk drives.
