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 type of multimode fiber-optic cable that reflects the light-based signals like a mirror within the cable - resulting in different signals arriving at different times and with an increased likeihood of distortion over longer cable runs.






2. Resistance that contributes to controlling an electrical signal; measured in ohms






3. Manages end-to-end delivery of data






4. Assigning a placeholder to each piece of a block of data to allow the receiving node's Transport layer to reassemble the data in the correct order






5. 1-126






6. Which layer in the OSI is responsible for routing and controling the flow of packets around the network?






7. A series of interconnected computers - printing devices - and other computer equipment that share hardware and software resources. The services area usually is limited to a given office - floor - or building.






8. 7th layer; protocols enable software programs to negotiate formatting - procedural - security - synchronization - and other requirements with the network

12. Frequency division multiplexing






13. Which class of IP address would be allocated to a very large company?






14. Electromagnetic interference. waves from electrical devices. ex. RFI






15. Source emits a RTS (request to send) signal to the access point - and the access point replies with CTS (clear to send) for the source to begin its transmission






16. Provides a generic method of transferring files






17. An IP addressing and subnetting method in which network and host information is manipulated without adhering to the limitations imposed by traditional network class distinctions. CIDR is also known as classless routing or supernetting. Older routing






18. Sequences packets in correct order






19. IEEE 802.3 Media Access Control (MAC) sublayer of the data link layer






20. Fiber Distributed Data Interface






21. Rules determining the format and transmission of data






22. SMF






23. Equivalent to OSI Layer 4 Transport






24. Does not operate at the application layer






25. 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.






26. Allows for secure interactive control of remote systems






27. Accurate alarm events that do not pose significant threat to information security






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






29. Max size of data units on Ethernet networks






30. GSNW






31. ACL






32. DSU






33. Pieces of hardware that connect the wire to the network device






34. Speed: 100 Mbps - Alternative name: 10BASE-TX - IEEE Standard: IEEE 802.3u - Cable Type: Copper - max length 100m






35. Packet a node sends to acknowledge that it received a SYN request for connection; 2nd of three-step connection process






36. A type of address translation in which each private IP address is correlated with its own Internet-recognized IP address.






37. The gateway that first interprets a device's outbound requests - and then interprets its inbound requests to and from other subnets.






38. Facilities necessary for a service provider to connect with another organization LAN or WAN






39. Transport layer protocol that services a request without requiring a verified session and without guaranteeing delivery data






40. Routers use it to identify nodes belonging to a multicast group






41. Reverse address resolution protocol






42. Institute of electrical and electronics engineers






43. Process in which an NIDPS look for invalid data packets - packets that are malformed under the rules of the TCP/IP protocol






44. POP3 - post office protocol 3






45. Frequency modulation-frequency of signal is modified






46. These reside on a computer or appliance connected to network segment and monitor network traffic






47. The _____________ allows certain bits of the IP address to be ignored when checking to see if an IP address matches the destination network address.






48. More variable - convey greater subtleties with less energy






49. A generic term for data being transmitted






50. A TCP/Ip troubleshooting utility that displays statistics and the state of current TCP/IP connections. It also displays ports - which can signal whether services are using the correct ports.
