An application layer address using TCP/IPv4 looks like:

False

TCP is the network layer protocol used on the Internet today.

TCP/IP

_______ is the dominant network protocol today.

approves which network layer addresses (usually, approved or assigned in groups or classes) can be used by an organization for its computers that will connect to the Internet

ICANN:

False

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

performs routing functions

IP:

routing table

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.

the transmission of status information "wastes" network capacity that could be used to send user messages

One drawback to dynamic routing is:

Domain name service

Server name resolution is done using the:

True

Subnet masks tell computers what part of an IP address is to be used to determine whether a destination is on the same subnet or on a different subnet.

performs packetizing, as well as routing and addressing functions

TCP/IP:

Transport

The ____________ layer links the application layer with the network layer and is responsible for end-to-end delivery of messages.

routing table

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

False

The most common standard for dynamic addressing for TCP/IP networks is Dynamic Host Control Protocol.

TCP connection

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.

False

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

160-bit

The options field in TCP segments is optional and rarely used. This results in a _____________ TCP header.

False

The standard port number for Telnet is 53

cetralized, static routing, and dynamic routing

The three fundamental approaches to routing are:

True

The transport layer process running on the destination computer reassembles the fragmented application message before passing it up to the application layer.

False

The transport layer routes messages thought the network selecting the best path from the source to the destination station.

True

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

hardware manufacturers

Typically, a client computer is assigned a data link layer address by:

HTTP requests

UDP is not commonly used for:

False

A multicast message can be used to send a message to a maximum of two other computers.

broadcast message

A special type of message that is used when sending the same message to all computers on a specific LAN or subnet is called a:

255.255.0.0

A subnet mask of ___________ means that all computers with only the same first two bytes in their IPv4 addresses are on the same subnet.

unicast message

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

True

An Address Resolution Protocol message is broadcast to all computers on a subnet to find the data link layer address.

True

An autonomous system is a network operated by one organization.

True

Because there is a limit on the length of a frame that the data link layer can transmit from node to node, the transport layer breaks up the message from the application layer into smaller packets.

DNS request packet

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

False

When using dynamic routing, routing decisions are always made by a central host or server.

UDP

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

application layer address

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?

Address Resolution Protocol

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

Routing

__________ is not an important function of the transport layer.

Routing

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

Server name resolution

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

static routing

____________ 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.
