MIS Appendix B Flashcards
(24 cards)
Client
A computer designed to request information from a server
Client/Server Network
A model for applications in which the bulk of the backbend 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.
Coaxial Cable
Cable that can carry a wide range of frequencies with low signal loss.
Ethernet
A physical and data layer technology for LAN networking.
Fiber Optic (or Optical Fiber)
Refers to the technology associated with the transmission of information as light impulses along a glass wire or fiber.
Internet Protocol Version 6 (IPv6)
The “next generation” protocol designed to replace the current version internet protocol, IP Version 4 (IPv4)
Interoperability
The capability of two or more computer systems to share data and resources, even though they are made by different manufacturers.
Local Area Network (LAN)
Connects a group of computers in proximity, such as in an office building, school, or home.
Metropolitan Area Network (MAN)
A large computer network usually spanning a city.
Network
A communications system created by linking two or more devices and establishing a standard methodology in which they can communicate.
Network Operating System (NOS)
Operating system that runs a network, steering information between computers and managing security and users.
Network Topology
Refers to the geometric arrangement of the actual physical organization of the computers (and other network devices) in a network.
Network Transmission Media
Refers to the various types of media used to carry the signal between computers.
Packet-Switching
Occurs when the sending computer divides a message into a number of efficiently sized units of data called packets, each of which contains the address of the destination computer.
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.
Protocol
A standard that specifies the format of data as well as the rules to be followed during transmission.
Router
An intelligent connecting device that examines each packet of data it receives and then decides which way to send it toward its destination.
Server
A computer dedicated to providing information in response to requests.
Telecommuncation System
Enables the transmission of data over public or private networks.
Transmission Control Protocol/Internet Protocol (TCP/IP)
Provides the technical foundation for the public Internet as well as for large numbers of private networks.
Twisted-Pair Cable
Refers to a type of cable composed of four (or more) copper wires twisted around each other within a plastic sheath.
Wide Area Network (WAN)
Spans a large geographic area such as a state, province, or country.
Wire Media
Transmission material manufactured so that signals will be confined to a narrow path and will behave predictably.
Wireless Media
Natural parts of the Earth’s environment that can be used as physical paths to carry electrical signals.
