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.

An application layer address using TCP/IPv4 looks like:
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.
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.
False
TCP is the network layer protocol used on the Internet today.
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:
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?
TCP/IP
_______ is the dominant network protocol today.
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.
