Computer Engineering Networking

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. 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.






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






3. 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.






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






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






6. 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.






7. Person working on the computer






8. Wide Area Network






9. A physical and data layer technology for LAN networking






10. 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.






11. A computer that uses the services of another program






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






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






14. Simple Mail Transfer Protocol






15. 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.






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






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






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






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






20. File Transfer Protocol






21. 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.






22. 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.






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






24. Personal area network






25. 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.






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






27. 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






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






29. 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.






30. 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






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






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






33. 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






34. 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.






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






36. An expansion card used for networking.






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






38. 32 bit number - four octets - contains network and host info






39. The physical layout of a computer network






40. 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






41. Local Area Network






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






43. Hyper Text Transfer Protocol






44. Ethernet connector
