___________ is the translation of application layer addresses into IP addresses.

The TCP portion of TCP/IP performs linking to the application layer.

_______________ is a type of dynamic routing.

__________ is not an important function of the transport layer.

A type of message that is used when sending a message from one computer to another computer is called a:

Part of the function of address resolution is translating the application layer address of the destination into a network layer address.

The latest version of IP is IPv7, which increases the address space from 128 bits to 256 bits.

In its simplest form, the __________ has two columns: the first column lists every computer and device in the network, while the second column lists the computer or device to which that computer should send messages, if they are destined for the computer in the first column.

Which of the following is not a protocol used at the application layer.

___________ is the process of determining the path that a message will travel from sending computer to receiving computer.

Connectionless routing sets up a TCP connection, or virtual circuit between a sender and receiver.

IPv4 addresses offer unlimited opportunity for expansion and growth on the Internet.

The _____________ is used by a computer to determine how messages will travel through the network.

The transport layer must break messages from the application layer into several _____ that can be sent to the data link layer.

A special type of message that is used when sending the same message to a specific group of computers is called a:

TCP uses _____________ so that the destination station can reassemble the packets into the correct order.

The ping command uses the most basic interior routing protocol on the Internet, which is the:

When TCP/IP translates an application layer address into an IP address, it sends a special __________ to the nearest DNS server.

UDP is not commonly used for:

_________ is a specially formatted request used to perform IP address to data link address resolution.

Enhanced Interior Gateway Routing Protocol is a dynamic link state interior routing protocol developed by Cisco.

______________ routing is most commonly used when the application data or message can fit into one single packet.

With ________ routing, computers or routers count the number of hops along a route and periodically exchange information on the hop count with their neighbors.

IGMP refers to:

Assume that more than one application program is using the same communications line on a particular computer. To be able to decide to which application program a message should be delivered on this computer, TCP/IP relies on the:

TCP includes a sequence number so that the packets can be reassembled at the destination in the correct order.

TCP/IP operates only as connection-oriented.

There are four fundamental approaches to routing: centralized, static routing, dynamic routing, and monitor routing.

An autonomous system is a network operated by one organization.

A majority of routers use the following operating system:

A routing protocol used inside an autonomous system is called an exterior routing protocol.

The ______ defines what type of packets should be routed and what types of packets should be discarded.

Domain Name Servers provide the equivalent of directory assistance for application layer addresses.

A(n) ________ refers to a group of computers that are logically grouped together by IP number.

Source port address is the logical address generated by the application layer on the source computer to identify the application, which is sending the data.

Which of the following is not given to a client computer when it is first installed on a TCP/IP network so that it has the appropriate routing/addressing information?

The newer form of IP, version 6 (Ipv6):

The source port identifier in the TCP header tells the TCP software on the destination computer, which application on the destination it should pass the packet to.

An advantage of centralized routing is:

____________ refers to the type of routing in which the routing table is developed by the network manager and modifications are made only when computers are added to or removed from the network.

A client computer is assigned a data link layer address is by:

Routing is the process of determining the path or route through the network that a particular message will follow from the sender to the recipient.

IPv4 uses ________ bytes per Internet address.

The negotiation by the transport layer at the sender with the transport layer at the receiver to determine what size packets should be set up is done via establishing a(n) ___________ between the sender and receiver.

IP is responsible for error-free delivery of packets on a TCP/IP network.

The three fundamental approaches to routing are:

Translating an application layer address to a network layer address and finally to a data link layer address is called address resolution.

_____________ routing is a method of routing in which each packet makes its own way through the network.

_______ is the dominant network protocol today.

The network layer is responsible for end-to-end delivery of the message.
