Node: each computer or device on a network is called a
Microwave: Radio waves that can provide a high-speed signal transmission
G Rokster: jj
MAN (Metroppolitan Area Network): High-speed network that connects local area networks in a metropolitan area such as a city or town and handles the bulk of communications activity across that region
Infrared: j
Fiber Optic Cable: j
TCP/IP (Transmission Control Protocol/ Internet Protocol): Network technology that manages data transmission by dividing it up into packets. Internet transmissions commonly use TCP/IP. TCP/IP is short for Transmission Control Protocol/Internet Protocol
P2P (peer to peer network): Type of peer-to-peer network on which users connect directly to each other's hard disks and exchange files over the Internet. Also called a file sharing network
Bit Torrent: j
Client/ Server Network: Type of network in which one or more computers act as a server and the other computers on the network request services from the server
Analog/ digital: vhs vs dvd
Computer Voice Mail: computer converts voice mail from analog to digital
Intranet: Internal network that uses Internet technologies
Ring Network: Type of network in which a cable forms a closed loop, or ring, with all computers and devices arranged along the ring. Data transmitted on a ring network travels from device to device around the entire ring, in one direction
ATM (Asynchromonous Transfer Mode): j
ISDN (Integrated Services Digital Network): Technology that provides higher-speed Internet connections using regular copper telephone lines. Also called Integrated Services Digital Network
Twisted--Pair Cable: One or more twisted-pair wires that have been bundled together. Twisted-pair cable is one of the more commonly used transmission media for network cabling and telephone systems
VAN ( Value Added Network): Third-party business that provides networking services such as secure data and information transfer, e-mail, and management reports
Hot Spot: Area with the capability of wireless Internet connectivity
GPS (global positioning service): Navigation system that consists of one or more earth-based receivers that accept and analyze signals sent by satellites in order to determine the receiver's geographic location
CATV (Cable Transmission Network): f
T- carrier: Any of several types of long-distance digital telephone lines that carry multiple signals over a single communications line by using multiplexing. T-carrier lines provide very fast data transfer rates
DSL (Digital Subscriber Line): j
3G Network (cellular radio technology): uses cellular radio technology to provide users with high-speed internet connections, as long as they are within the networks range
Infrared light waves: f
Phone Line Network: easy to install and inexpensive netowrk that uses existing telephone lines int the home
Internet Telephony: Use of the Internet, instead of the public switched telephone network, to connect a calling party and one or more called parties. Also called Voice over IP (VoIP)
ATM( asynchromous transfer mode): Service that carries voice, data, video, and multimedia at extremely high speeds. Telephone networks, the Internet, and other networks with large amounts of traffic use ATM. ATM is short for Asynchronous Transfer Mode
Home RF (broadcast radio signal): f
Token Ring Network: Type of network technology that controls access to a network by requiring that devices on the network share or pass a special agent, called a token. Only one token exists per network, and only the device with the token can transmit data over the netw
Protocol: f
GPS (Global Positioning System): is a navigation system that consists of one or more earth-based recievers that accept and analyze signals sent by satellites in order to determine the reciever's geographic location.
RFID (radio frequency identification): A technology that uses radio signals to communicate with a tag placed in an object, an animal, or a person.
WAp (Wireless Application Protocol): Communication protocol that allows wireless mobile devices such as smart phones and PDAs to access the Internet and its services
Ethernet: Type of network technology that allows nodes to contend for access to a network. If two computers on the network attempt to send data at the same time, a collision occurs, and the computers must attempt to send their messages again. Etherne
Noise: Electrical disturbance that can degrade communications
Bus Network: Type of network that consists of a single central cable, called a bus, to which all computers and other devices connect. Data, instructions, and information travel in both directions on a bus network
WLAN (Wireless LAN): Type of LAN that uses no physical wires
WiFi (broadcast radio signal): f
Baseband: f
WAP (Wireless Application Protocol): Communication protocol that allows wireless mobile devices such as smart phones and PDAs to access the Internet and its services
T1: The most popular T-carrier line, which is used by many Internet access providers to connect to the Internet backbone and often is used by businesses to connect to the Internet
Bluetooth (broadcast radio signal): Wireless communication standard that uses short-range radio waves to transmit data between two Bluetooth devices
Coaxial Cable: j
Satellite: downlink vs uplink: f
WISP (Wireless internet service provider): type of internet service provider that provides wireless internet access to computers with wireless modems or access devices or to internet enabled mobile devices
LAN (Local Area Network): Network that connects computers and devices in a limited geographical area such as a home, school computer laboratory, office building, or closely positioned group of buildings. LANs often are used to share resources such as printers, large hard disks, and programs
Transmission Media: Materials or substances that are capable of carrying one or more signals on a communications channel
Modem- wireless modem: Type of communications device that either converts a computer's digital signals into analog signals so the signals can be transmitted over standard telephone lines or converts the analog signals back into digital signals that a computer can process Also called a dial-up modem
802.11 (WiFi or Wireless Fidelity): (WiFi) and wireless ethernet is a series of network standards that specifies how two wireless devices sommunicate over the air with each other
WiMax (Worldwide Interoperable for Microwave Access): f
Home RF Network (wireless home network): j
Star Network: Type of network in which all of the computers and devices, or nodes, on the network connect to a central device, thus forming a star. The central device that provides a common connection point for nodes on the network is called the hub. All data that transfers from one node to another passes through the hub.
