Networks and Telecommunications Flashcards
(44 cards)
telecommunication system
Enables the transmission of data over public or private networks.
telecommunication system
Enables the transmission of data over public or private networks.
local area network (LAN)
Designed to connect a group of computers in proximity to each other such as in an office building, a school, or a home.
wide area network (WAN)
Spans large geographic area, such as a state, province, or country.
metropolitan area network (MAN)
A large computer network usually spanning a city.
peer-to-peer (P2P) network
A computer network that relies on the computing power and bandwidth of the participants in the network rather than a centralized server.
A computer network that relies on the computing power and bandwidth of the participants in the network rather than a centralized server.
A model for applications in which the bulk of the back-end processing, such as performing a physical search of a database, takes place on a server, while the front-end processing, which involves communicating with the users, is handled by the clients.
network operating system (NOS)
The operating system that runs a network, steering information between computers and managing security and users.
packet-switching
Occurs when the sending computer divides a message into a number of efficiently sized units called packets, each of which contains the address of the destination computer.
router
An intelligent connecting device that examines each packet of data it receives and then decides which way to send it onward toward its destination.
protocol
A standard that specifies the format of data as well as the rules to be followed during transmission.
network topology
Refers to the geometric arrangement of the actual physical organization of the computers (and other network devices) in a network.
interoperability
Capability of two or more computer systems to share data and resources, even though they are made by different manufacturers.
ethernet
A physical and data layer technology for LAN networking.
transmission control protocol/Internet protocol (TCP/IP)
Provides the technical foundation for the public Internet as well as for large numbers of private networks.
Internet protocol version 6 (IPv6)
The “next generation” protocol designed to replace the current version Internet protocol.
network transmission media
Various types of media used to carry the signal between computers.
wire media
Transmission material manufactured so that signals will be confined to a narrow path and will behave predictably.
twisted-pair cable
A type of cable composed of four (or more) copper wires twisted around each other within a plastic sheath.
fiber-optic (optical fiber)
The technology associated with the transmission of information as light impulses along a glass wire or fiber.
coaxial cable
Cable that can carry a wide range of frequencies with low signal loss.
wireless media
Natural parts of the Earth’s environment that can be used as physical paths to carry electrical signals.
network
A communications system created by linking two or more devices and establishing a standard methodology in which they can communicate.
local area network (LAN)
Designed to connect a group of computers in proximity to each other such as in an office building, a school, or a home.
