Business Data Communications and Networking Study Set 1

By offloading printing tasks from the main LAN server, a print server increases network efficiency.

The Ethernet standard was developed first by the IEEE.

Network profile refers to what resources on each server are available on the network for use by other computers and which devices or people are allowed access on the network.

Many network hubs incorporate repeaters or amplifiers to regenerate signals so that attenuation of the signal does not occur.

Fiber optic cable is thicker and heavier than unshielded twisted pair.

Ethernet is a layer 3 protocol, which operates at the network layer.

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

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

The three latest versions of Ethernet run at speeds of 1Gbps, 10Gbps, and 50 Gbps.

1000Base-LX is a version of 1000Base-T than runs on four pairs of CAT 5 cable.

A hardware device that is not included in a network profile cannot be accessed by another computer on the network.

Traditional Ethernet is also known as shared Ethernet.

LDAP is an industry standard directory protocol.

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.

A switch always broadcasts all the packets it receives to all the computers that are connected to the switch.

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.

Topology refers to the geometric layout of the network and describes how the computers are interconnected.

A collision on a bus circuit means that two computers on that circuit have transmitted at the same time.

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

LANs that run on radio frequencies use a type of wired media.
