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 unit of data formatted for transmission over a network that contains control and other information that corresponds to the OSI Networklayer; also called Layer 3.






2. Not individually insulated but shielded. use when there is noise.






3. Theoretical. difference b/w highest and lowest frequency.






4. NCP






5. Set of routines that make up part of a software application






6. 128 -64 -32 -16 -8 -4 -2 -1






7. Central component of a cable designed to carry a signal






8. Cause by EMI/RFI - and other packets - interference on the signal






9. Communications that occur in discrete units where the start of a unit is signaled by a start bit at the front and the end of the unit is signaled by a stop bit at the back.






10. The act of hacking into a hacker's system to find out as much as possible about the hacker






11. 1000 representatives from industry and gov't who determine standards for electronics - chemical and nuclear engineering - health and safety - and construction






12. A shell protocol that enables systems to use various authenticaion mechanisms.






13. Network-max segment length-100 meters






14. Prevents broadcast storms by enabling switches to calculate paths that avoid potential loops and artificially block the links that would complete a loop






15. Transport Layer






16. 4th layer; protocols ensure that data are transferred from point A to point B reliably and without errors; services include flow control - acknowledgment - error correction - segmentation - reassembly - and sequencing






17. HTTPS - Secure implementation of HTTP






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






19. An Application layer protocol used to retrieve messages from a mail server. When a client retrieves mail via POP - messages previously stored on the mail server are downloaded to the client's workstation - and then deleted from the mail server.






20. As defined by the EIA/TIA-568 standard - cable that runs between network equipment rooms - floors - and buildings.






21. Receives a signal on one end - interprets it as 0 & 1 - then generates a new clean signal on the other end.






22. Equivalent to OSI Layer 2 Data Link & Layer 1 Physical






23. Degradation of a light signal on a fiber-optic network






24. The most popular type of network for medium- and large-scale organizations






25. Faster networking and inexpensive - flexible - easy to install






26. You may set up a web server on companys access server - allowing global connections - for employees to access






27. To make more efficient use of limited numbers of legitimate IP addressing






28. Local area network






29. F type (like TV cable) or BNC (crimped)






30. Strategy in which all control functions are applied at the physical location of each IDPS component






31. Packet one node sends to request a connection with another; 1st of three-step process of establishing a connection






32. The communication between two networking devices for the purposes of the functions defined at a particular layer of a networking model - with the communication happening by using a header defined by that layer of the model. The two devices set values






33. Simple Network Management Protocol






34. 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.






35. VPN






36. A transmitter concentrates the signal energy at a single frequency or in a very small range of frequencies






37. The IEEE standard for Ethernet networking devices and data handling (using the CSMA/CD access method)






38. Equals a single pulse in the digital encoding system






39. AM






40. A type of interference that occurs when two LAN cables run close to each other. If one cable is carrying a signal and the other isn't - the one carrying a signal will induce a 'ghost' signal in the other cable






41. Hardware that constitutes the enterprise-wide cabling system






42. Any end device on the network (for example: computers - printers - copy machines...)






43. 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.






44. The oldest type of network design with - this topology consist fo multiple nodes attached to a central hub - switch - or router.






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






46. Term that describes current anti-intrusion technologies






47. ADSL






48. Name Of Layer 6






49. International society composed of engineering professionals with goals of promoting development and education in the electrical engineering and computer science fields






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