A collection of computers and devices connected together

The devices that are used in a network

Token Ring
Specifies that computers and devices on the network shapr or pass a special signal (or token)

A network standard that defines how messages are routed from one end of a network to another

WI-FI (wireless fidelity)
Identifies any network based on the 802.11 standard that facilitates wireless communication

Internal network that uses internet technology

standard that specifies no computer controls when data can be transmitted

Local Area Network (LAN)
A network that connects computers and devices in a limited geographical area (e.g. home, school computer lab, office building))

Wireless LAN (WLAN)
A LAN that has no physical wires

Standard the outlines characteristics of how network devices communicate

Star Network
all of the computers and devices on the network connection to a central device

Bus Network
Consists of a central cable to which all computers and other devices connect

Ring Network
Cable forms a closed loop with all computers and devices arranged along the ring

Metropolitan Network

Wide Area Network (WAN)
A network that covers a large geographic area (e.g A city, country,or world)using communications channel that combines many and radio waves

Client/Server Network
one or more computers act as a server and the other computers on the network request services from the server. Server holds resources while Client requests what is held

Peer to Peer Network (P2P)
Internet network on which users access each other’s hard disk and exchange files directly over the internet

The device that provides a common central connection point for nodes on a network

a communtions device that connects mulitiple computers or other routers together and transmits data to its correct destination on a network

A combination of hardwares and softwares that connects one network to another

Types of Protocol
Enthernet, token ring,TCP/IP, Wi-Fi, Bluetooth, UWB, IrDA,RFID, WiMAX, and WAP

Graphic Card
a printed circuit board that controls the output to a display screen

Disk defragmenter
designed to increase access speed by rearranging files stored on a disk to occupy contiguous storage locations

Cloud Computing
the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.

Porpose of the Https Protocol
Hypertext teansfer protocol over secure socket layer. It means the web browser connection is being used will be encrypted and not accessible by hackers

IP address
a unique string of numbers separated by periods that identifies each computer using the Internet Protocol to communicate over a network.
