Network+ Guide To Networks Chapter 1 - Introduction To Networking

Front 1

A unique network layer address assigned to each node on a TCP/IP network. IPv4 consists of 32 bits divided into 4 octets, or bytes. IPv6 are composed of eight 16 bit fields for a total of 128 bits.

Back 1

IP address

Front 2

The scheme for assigning a unique identifying number to every workstation and device on the network. The type of _________ used on a network depends on its protocols and network operating system.

Back 2

addressing

Front 3

The part of a network to which segments and significant shared devices (such as routers, switches, and servers) connect. It is sometimes referred to as a 'network of networks' because of its role in interconnecting smaller parts of a LAN or WAN.

Back 3

backbone

Front 4

A computer on the network that requests resources or services from another computer on a network. In some cases, a _____ could also act as a server. The term may also refer to the user of a workstation or a software application installed on the workstation.

Back 4

client

Front 5

A network design in which client computers use a centrally administered server to share data, data storage space, and devices.

Back 5

client/server architecture

Front 6

A network that uses centrally administered computers, know as servers, to enable resource sharing for and to facilitate communication between the other computers on the network.

Back 6

client/server network

Front 7

The use of data networks to carry voice (or telephone), video, and other communications services in addition to data.

Back 7

convergence

Front 8

A specialized server that enables clients to share applications and data across the network.

Back 8

file server

Front 9

The functions of a file server that allows users to share data files, applications, and storage areas.

Back 9

file services

Front 10

A computer that enables resource sharing by other computers on the same network.

Back 10

host

Front 11

A network of computers and other devices that is confined to a relatively small space, such as one building, or even one office.

Back 11

LAN (local area network)

Front 12

A network that is larger than a LAN, typically connecting clients and servers from multiple buildings, but within a limited geographic area. For example, it could connect multiple city government buildings around a city's center.

Back 12

MAN (Metropolitan Area Network)

Front 13

A group of computers and other devices (such as printers) that are connected by and can exchange data via some type of transmission media, such as a cable, a wire, or the atmosphere.

Back 13

network

Front 14

The resources a network makes available to its users include applications and the data provided by these applications. These resources are usually referred to as?

Back 14

network services

Front 15

The device that enables a workstation to connect to the network and communicate with other computers. They are manufactured by several different companies and come with a variety of specifications that are tailored to the workstation's and the network's requirements. Also called network adapters.

Back 15

NIC (network interface card)

Front 16

Any computer or device on a network that can be addressed on the local network.

Back 16

node

Front 17

The software that runs on a server and enables the server to manage data, users, groups, security, applications, and other networking functions. The most popular ones are UNIX, Linux, and Microsoft Windows Server 2008 R2.

Back 17

NOS (network operating system)

Front 18

A discrete unit of information sent from one node on a network to another. Consists of the entire Network layer message, which includes the segment (TCP) or datagram (UDP) from the Transport layer, plus the Network layer header.

Back 18

packet

Front 19

A network in which every computer can communicate directly with every other computer. By default, no computer on this type of network has more authority than another. However, each computer can be configured to share only some of its resources and keep other resources inaccessible to other nodes on the network.

Back 19

peer-to-peer network

Front 20

The network service that allows printers to be shared by several users on a network.

Back 20

print services

Front 21

A standard method of format for communication between network devices. For example, some ensure that data are transferred in sequence and without error from one node on the network to another. Others ensure that data belonging to a Web page are formatted to appear correctly in a Web browser window. Still others encode passwords and keep data transmissions secure. AKA, a method of rules for communication.

Back 21

protocol

Front 22

A service used to manage remote applications. Included in Windows 2008 and after.

Back 22

Remote Desktop Services

Front 23

A service used prior to Windows Server 2008 that is used to manage remote applications.

Back 23

Terminal Services

Front 24

The property of a network that allows you to add nodes or increase its size easily.

Back 24

scalable

Front 25

A part of a network. Usually composed of a group of nodes that share the same communications channel for all their traffic.

Back 25

segment

Front 26

This device receives incoming data from one of its ports and redirects it to another port or multiple ports that will send the data to its intended destination(s).

Back 26

Switch

Front 27

The physical layout of computers on a network.

Back 27

topology

Front 28

The centralized management of multiple types of network-based communications, such as voice, video, fax, and messaging services.

Back 28

Front 29

A network that spans a long distance and connects two or more LANs.

Back 29

WAN (wide area network)
