Chapter 1: Introduction Flashcards
Address
A number that uniquely identifies each workstation and device on a network. Without unique addresses, computers on the network could not reliably communicate.
Address Management
The process of centrally administering a finite number of network addresses for an entire LAN. Usually this task can be accomplished without touching the client workstations.
Addressing
The scheme for assigning a unique identifying number to every workstation and device on a network. The type of addressing used on a network depends on its protocols and network operating system.
Asset Management
The process of collecting and storing data on the number and types of software and hardware assets in an organizations network. The data collection. Is automated by electronically examining each network client from a server.
Backbone
The part of a network to which segments and significant shared devices (such as routers, switches, and servers) connect. A backbone is sometimes referred to as “a network of networks” because of its role in interconnecting smaller parts of a LAN or WAN.
Backing Up
The process of copying critical data files to a secure storage area. Often, backups are performed according to a formulaic schedule.
CCIE(Cisco Certified Internetwork Expert)
An elite certification that recognizes expert-level installation, configuration, management, and troubleshooting skills on networks that use a range of Cisco Systems devices.
CCNA (Cisco Certified Network Associate)
A professional certification that attests to ones skills in installing, configuring, maintaining, and troubleshooting medium-sized networks that use Cisco systems switches and routers.
Client
A computer on the network that requests resources or services from another computer on a network. In some cases, a client could also act as a server.
Client/Server Architecture
A network design in which client computers use a centrally administered server to share data, data storage space, and devices.
Client/Server Network
A network that uses centrally administered computers, known as servers, to enable resource sharing for and to facilitate communication between the other computers on the network.
Connectivity Device
One of several types of specialized devices that allows two or more networks or multiple parts of one network to connect and exchange data.
Convergence
The use of data networks to carry voice (or telephone), video, and other communications services in addition to data.
File Server
A specialized server that enables clients to share applications and data across the network.
File Services
The functions of a file server that allow users to share data files, applications, and storage areas.
Host
A computer that enables resource sharing by other computers on the same network.
Internet
A complex WAN that connects LANs and clients around the globe.
Internet Services
The services that enable a network to communicate with the internet, including web servers and browsers, file transfer capabilities, internet addressing schemes, security filters, and a means for directly logging into other computers.
LAN
A network of computers and other devices that is confined to a relatively small space, such as one building or even one office.
License Tracking
The process of determining the number of copies of a single application that are currently in use on the network and whether the number in use exceeds the authorized number of licenses.
Load Balancing
The process of distributing data transfer activity evenly so that no single device is overwhelmed.
Mail Server
A server that manages the storage and transfer of e-mail messages.
