Subject : engineering
Instructions:
  • Answer 44 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 domain is a trusted group of computers that share security - access control - and have data passed down from a centralized domain controller server or servers.






2. Bandwidth describes the amount of data which can be transmitted via a network connection - usually measured in bits per second.






3. A TCP/IP network that uses addresses starting between 1 and 126 and supports up to 126 subnets with 16 -777 -214 unique hosts each.






4. In IPv4 addressing - a 32- bit number that - when combined with a device's IP address - indicates what kind of subnet the device belongs to.






5. Local Area Network






6. Also called 10Base5. Bus network that uses a thick coaxial cable and runs Ethernet up to 500 meters.






7. The delay between asking for data from an I/O device and the beginning of data transfer.






8. Simple Mail Transfer Protocol






9. Also called 10Base2. Bus network that uses a thin coax cable and runs Ethernet media access up to 185 meters.






10. A device for transmitting data on a network. A switch makes decisions - based on the Media Access Control (MAC) address of the data - as to where the data is to be sent.






11. A TCP/IP network that uses addresses starting between 192 and 254 and supports up to 2 -097 -152 subnets with 254 unique hosts each.






12. A junction where information arrives from connected computers or peripheral devices and is then forwarded in one or more directions to other.






13. Hardware and/or software that guards a private network by analyzing the information leaving and entering the network






14. A protocol for communication between individual computers and the Internet.






15. Category 5e wire - a TIA/EIA standard for UTP wiring with improved support for 100 Mbps using two pairs - and support for 1000 Mbps using four pairs.






16. A physical and data layer technology for LAN networking






17. File Transfer Protocol






18. 32 bit number - four octets - contains network and host info






19. The physical layout of a computer network






20. Ethernet connector






21. A term used to describe a short - connectorized cable that can serve several different purposes in different contexts - such as linking together two MAUs or connecting a network device - such as switch - to a patch panel






22. An IP address reserved for communicating from a node to itself (used mostly for troubleshooting purposes). The IPv4 loopback address is always cited as 127.0.0.1 - although in fact - transmitting to any IP address whose first octet is 127 will contac






23. Twisted pair patch cable in which the termination locations of the transmit and receive wires on one end of the cable are reversed






24. Personal area network






25. Defense Advanced Research Projects Agency - developed ARPAnet in 1969






26. An expansion card used for networking.






27. Taking a system and using it as a distribution system for other systems.






28. A TCP/IP network that uses addresses starting between 128 and 191 and supports up to 16 -384 subnets with 65 -534 unique hosts each.






29. A peer- to- peer network. That is - each computer is sustainable on its own. Each PC has its own user list - its own access control - and its own resources. In order for a user to access resources on another workgroup computer - that user must be set






30. Temporarily stores new messages on an e- mail server.






31. Unshielded Twisted Pair does not have a grounded outer copper shield. UTP cables are easier to work with and are less expensive than shielded cables. Example: RJ-45.






32. Person working on the computer






33. Subdivisions of a Class A - B - or C network - as configured by a network administrator. Subnets allow a single Class A - B - or C network to be used instead of multiple networks - and still allow for a large number of groups of IP addresses - as is






34. Copper cable with RJ-45 connectors in which the wire at pin 1 on one end is connected to pin 1 on the other end; the wire at pin 2 is connected to pin 2 on the other end; and so on.






35. IPv6 An extended scheme of IP addresses - using 128- bit IP addresses - that allows for more IP addresses than current system - IPv4 - which uses 32- bit IP addresses.






36. Wide Area Network






37. A computer that handles requests for data - e- mail - file transfers - and other network services from other computers (clients)






38. Hyper Text Transfer Protocol






39. The amount of information that can pass through a system in a given amount of time






40. Base-2 number system that is used as the base for computer code.






41. A computer that uses the services of another program






42. An intelligent connecting device that examines each packet of data it receives and then decides which way to send it onward toward its destination.






43. A device or system which can receive information from and send information to a computer system






44. Model for understanding and developing computer- to- computer communication developed in the 80s by ISO; divides networking functions among 7 layers.
