Protocols and Standards

1.) SNMP, SMTP, FTP, TELNET, HTTP, NCP, SMB, and Appletalk are protocols that operate at the OSI ___________ layer.

2.) The _____________ layer encodes and converts user information into binary data, also provides protocol conversion, encryption, and compression.

3.) The _____________ layer opens manages, and closes conversations between two computers. It performs name recognition and the functions such as security, needed to allow two applications to comminicate over the network, also provides error handling.

4.) The ______________ layer routes data packets across network segments. Translates logical addresses and names into physical addresses.

5.) _____ is the standard for data packet delivery over the Internet.

6.) ______ runs on top of IP and is used as an alternative to TCP.

7.) ________ is used to tranfer mail messages between two remote computers. It is used on the Internet, and is part of the TCP/IP protocol stack.

8.) ________ is http using a Secure Socket Layer (SSL).

9.) The first digit of a Class ___ address will be a number between 192 and 223, the network ID start bit is 110 and their default subnet mask is 255. 255. 255.0

10.) Most e-mail applications use the ______protocol, although some use the newer ________.

11.) ___________ is short for Telecommunication Network, a virtual terminal protocol allowing a user logged on to one TCP/IP host to access other hosts on the network.

12.) Dynamic Host Configuration Protocol is a ____________ service. When a DHCP server is configured on a network , clients that support DHCP can request _________ configuration information from the server.

13.) _________ ____________ _________, enables short alphabetical names to be assigned to IP addresses to describe where a computer is located.

14.) The first digit of a Class ___ address will be a number between 128 and 191, the network ID start bit is 10 and the default subnet mask is 255. 255.0.0

15.) If the routers that connect subnets are RFC 1542 compliant routers, the DHCP/_________ relay agent can provide IP addresses to clients in multiple subnets.

16.) While ________ resolves host names to IP addresses, WINS resolves _____________ names to IP addresses.

17.) _________ uses small utility programs called agents to monitor behavior and traffic on the network, in order to gather statistical data.

18.) The first digit of a Class ___ addresses will be a number between 1 and 126, the network ID start bit is 0 and default subnet mask is 255.0.0.0

19.) A _____________ is a device used to connect networks using different protocols.

20.) A ____________ mask is used to mask a portion of the IP address, so that TCP/IP can tell the difference between the network ID and the host ID.

21.) WAN technologies use either ___________ switching or ____________ switching as a connection method.

22.) _____________ switching offers more efficient use of a telecommunication provider's network bandwidth.

23.) With ___________ switching, data travels over a fixed path that is established at the beginning of the connection and remains open until the connection is terminated.

24.) _________ adapters must be connected directly to a digital telephone network.

25.) ISDN hardware requires a ______ device, which converts network data signals into the signaling protocols used by ISDN.

26.) _________, shares many of the same features as token ring, such as a token passing, and the continuous network loop configuration, but has better fault tolerance

27.) _______ uses fixed sized packets of 53 bytes long called cells and provides data transfer rates from 25 Mbps to 2400 Mbps.

28.) Optical Carrier (OC), designations are used to specify the speed of fiber optic networks that conforms to the ___________ standard.

29.) An authentication system, _______________ is designed to enable two parties to exchange private information across an open network. It works by assigning a unique key, called a ticket, to each user that logs on to the network.
