Subject : it-skills
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 common way of sharing resources on a peer-to-peer network






2. A type of point-to-point digital WAN connection that uses standard phone lines to provide high-speed comm.






3. Speed: 1000 Mbps - Alternative name: 1000BASE-LX - 1000BASE-SX - IEEE Standard: IEEE 802.3z - Cable Type: Fiber max length 550m (sx) - 5 km(lx)






4. Data Link Layer






5. Restructuring data units that have been segmented






6. (fix) if analog shield twisted pairs or if digital with a repeater






7. Point to point protocol






8. Connection-less






9. A fixed number associated with a device's NIC






10. CRAM-MD5






11. A system of computers - printer devices - network devices - and computer software linked by communications cabling or radio waves.






12. Glass/plastic - light pulses high throughput - resistant to noise - most expensive cable






13. A connecting device for a network that accepts messages and forwards them to the correct section of the network. Generally more intelligent than a hub and a switch.






14. A transmission method that has distinct signal levels to represent binary zeroes or ones - such as +5 volts and 0 volts.






15. RSA






16. Four twisted wire pairs rated for 100 Mhz - but capable of handling the disturbance on eash pair that's caused by transmitting on all four pairs at the same time.






17. IEEE standard for wireless networking






18. Developed by ISO and ANSI - a model that providees a framework for networked hardware and software communication based on seven layers.






19. The first set of six characters that make up the MAC address and that are unique to a particular manufacturer.






20. Transport Layer






21. An international body that establishes communications and networking standards - and that is particularly known for its contributions to network protocol standards.






22. Process of directing a datagram from its source through an internetwork to its destination using the most efficient path.






23. ISDN






24. One transmitter issues signals to multiple receivers; receivers may be undefined or defined






25. Data Link Layer






26. A device used to connect thicknet cable with a transceiver. A vampire bypasses the need to serve the cable - because the vampire tap has a metal tooth that pierces through the outside cable insulation (like a vampire) and connects with the copper wir






27. Signals composed ot pulses that can have a value of only 1 or 0






28. SCP






29. Braided metal shielding used to insulate some types of coaxial cable






30. BERT






31. Transport Layer






32. Documented agreement containing technical specifications or other precise criteria used as guidelines to ensure that materials - products - processes - and services suit their intended purpose






33. A term used to refer to data within the Data-link layer of the OSI model.






34. A connecting device for a network that accepts messages and passes them on to other parts of the network. Generally more intelligent than a hub.






35. Response generated atTransport layer confirming to sender that its frame was received; 3rd step in establishing a connection






36. Provides service that ensure accurate and timely delivery of network communications between two hosts






37. Direct-sequence spread spectrum: signal bits are distributed over a frequency band






38. Default subnet mask for 154.13.44.87






39. Also called the physical or device address - the hexadecimal number permanently assigned to a network interface and used by the MAC sublayer within the DATA Link layer (Layer 2).






40. What is the term used when every host on the network has a fixed IP address?






41. A network whose access is restricted to only clients or machines with proper credentials.






42. 7th layer; protocols enable software programs to negotiate formatting - procedural - security - synchronization - and other requirements with the network






43. Multicast group 224-239






44. Nondata information that mus accompany data in order for a signal to be properly routed and interpreted by the network






45. Doesn't use frame headers - uses cells






46. A computer that has its own CPU and may be used as a stand-alone computer for word processing - spreadsheet creation - or other software applications. It also may be used to access another computer such as another workstation or server via a network.






47. Which layer is responsible for putting data into frames as well as providing error checking data?






48. Every node on the network is connected through a central device like a switch - cannot be disabled by a single malfunction in a workstation - scalable - - popular - expensive - cable malfunction will only effect 2 workstations - more fault tolerant.






49. Basic error correction and detection






50. CDFS
