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

True

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.

Domain Name Service

Server name resolution is done using the:

True

Source port address is the logical address used to identify the application that is sending the data.

half duplex

Stop-and-wait ARQ uses ___________ type of data flow.

True

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

True

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

sequence numbers

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

127

The _____ address range is reserved for a computer to communicate with itself and is called the loopback.

ACL

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

True

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

routing table

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

The most common protocol for dynamic addressing in TCP/IP networks is the Dynamic Host Configuration Protocol.

False

The network layer address for IP is ten bytes long when using IPv4.

False

The network layer sits directly between the application layer and the data link layer in the Internet five-layer network model.

192-bit

The older version of IP has a ________ header of control information.

Internet Control Message Protocol

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

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.

False

The standard port number for Telnet is 53.

centralized, static routing, and dynamic routing

The three fundamental approaches to routing are:

segments

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

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 through the network selecting the best path from the source to the destination station

False

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

True

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

connection-oriented

Cisco Internetwork Operating System (IOS)

A majority of routers use the following operating system:

False

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

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:

192-bit

A typical TCP segment has a _______ header of control information.

subnet

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

True

An Address Resolution Protocol message is broadcast to all computers in a subnet to find the data link layer address of a host whose IP address is known but whose MAC address is unknown.
