Data Communication & Networking - True - False - 5

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

Answer: True

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

Answer: True

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

Answer: 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.

Answer: True

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

Answer: True

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

Answer: False

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.

Answer: True

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

Answer: False

Resource sharing refers to having users access the same data files, exchange information via e-mail, or use the Internet.

Answer: False

On a network, it is always legal to purchase one copy of software, such as a word processing package, that multiple users use simultaneously.

Answer: False

LAN metering software can be used to prohibit using more copies of a package than there are installed licenses.

Answer: True

Software Publishers Association has embarked upon an aggressive software audit program to check the number of illegal software copies on LANs.

Answer: True

LANs can be categorized as either dedicated (with a dedicated server) or peer-to-peer (without a dedicated server).

Answer: True

Peer-to-peer networks have computers that are permanently assigned as network servers.

Answer: False

As discussed in this textbook, three layers of a network model are the components required for a typical network, including local area networks.

Answer: False

The Network Interface Card (NIC) permits a computer to be physically connected to a network's cable, which provides the network layer connection among the computers in the network.

Answer: False

A Network Operating System (NOS), such as Linux or Windows Server 2008, must be used in addition to the 'normal' operating system, such as Windows, on a server in a dedicated server LAN.

Answer: False

One of the most important functions of Network Operating System (NOS) is a directory service.

Answer: True

The NOS software for the server computer provides the physical, data link, and network layer functions.
