Essential Concepts and Terminology

Study Unit 10


Synergism l.jpg
Synergism.

  • The simultaneous action of separate agencies which, together, have a greater total effect than their separate effects.


Computer network l.jpg
Computer Network.

  • A collection of computers and related devices, connected in a way that allows them to share data, hardware, and software.


Terminal l.jpg
Terminal.

  • A device with a keyboard and a monitor, used for input and output, but not for processing.


Local area network lan l.jpg
Local Area Network (LAN).

  • An interconnected group of computers and peripherals located within a relatively limited area, such as building or a campus.


Network version software l.jpg
Network Version Software.

  • Applications designed for installation on a file server and made available to more than one user at a time.


Groupware l.jpg
Groupware.

  • Software that provides ways for multiple users to collaborate on a project, usually through a pool of data that can be shared by members of the workgroup.


Circuit switching l.jpg
Circuit Switching.

  • The method of establishing an end-to-end connect between computers for the duration of a data transmission.


Packet switching l.jpg
Packet Switching.

  • A technology employed by data communications networks, such as the Internet, whereby a message is divided into smaller transmission units called packets.


Router l.jpg
Router.

  • A computer at an intersection on a packet-switching network that examines IP addresses and forwards the data towards its destination on the least congested path.


Protocol l.jpg
Protocol.

  • In data communication and networking, a specifying standard governing data format and transmission rules.


Protocol suite l.jpg
Protocol Suite.

  • The total collection of protocols that define how a specific network's functions. Networks can employ dozens of protocols.


Protocol stack l.jpg
Protocol Stack.

  • A network architecture concept that describes the sequence of data handling, between the user and the physical media, by a series of protocols.


Network interface card nic l.jpg
Network Interface Card (NIC) .

  • A circuit board that enables sending and receiving data on a network.


Workstation l.jpg
Workstation.

  • A computer connected to a local area network.


Slide16 l.jpg
Node.

  • Each device on a network, including workstations, servers, printers, and other peripherals.


Client server network l.jpg
Client/Server Network.

  • A network with workstations (clients) and one or more the servers.


File server l.jpg
File Server.

  • In client/server computing, a high-capacity, high-speed computer dedicated to making files and programs available to client workstations and nodes.


Clients l.jpg
Clients.

  • In network computing, all the workstations that connect to and send requests to a server.


Topology l.jpg
Topology.

  • The physical layout of a network. The pattern of communications pathways, such as star, bus, and ring.


Collision l.jpg
Collision.

  • A disruption of communication that occurs when two packets are sent at the same time. Corruption of data caused by simultaneous transmission.


Ethernet l.jpg
Ethernet.

  • A LAN standard in which network nodes are connected by coaxial cable or twisted-pair wire. The most popular network architecture, capable of transmitting data at 10 Mbps to 1 Gbps.


Electronic data interchange edi l.jpg
Electronic Data Interchange (EDI).

  • A set of business-to-business standards to facilitate paperless financial transactions.
