Term
|
Definition
| is a design specification that indicates how the nodes on a network are constructed to communicate with one another |
|
|
Term
|
Definition
| a center host computer controls all network communication, and performs data processing and storage on behalf of clients |
|
|
Term
|
Definition
| servers provide resources to clients. In response to client request, servers provide authentication services and access to shared files, printers, hardware storage, and applications |
|
|
Term
|
Definition
| resource sharing, processing, and control of communications are completely decentralized. all clients on the network are equal in terms of providing and using resources, each workstation authenticates its users |
|
|
Term
|
Definition
| elements from more than one of the three standard networks models are incorporated |
|
|
Term
|
Definition
| describes the layout or shape, of a network's physical wiring and devices |
|
|
Term
|
Definition
| describes the configuration of the paths through which data moves on the network |
|
|
Term
|
Definition
| nodes are arranged in a liner format, and a T-connector connects each node directly to a network cable. the cable is called the bus and serves as a single communication channel |
|
|
Term
|
Definition
| contains a central connectivity device, such as a switch, with individual physical connections to each node |
|
|
Term
|
Definition
| each node is connected to the two nearest nodes-its upstream and downstream neighbor- to form a ring. data only flows in one direction to prevent data packet collisions |
|
|
Term
| physical dual ring topology |
|
Definition
| includes one ring within another . the two rings transmit data in the opposite direction |
|
|
Term
|
Definition
| each node connects directly to every other node, making it possible for each node to communicate with multiple nodes simultaneously |
|
|
Term
| physical partial-mesh topology |
|
Definition
| only a few nodes have direct links with all the other nodes. this makes it less complex and less expensive |
|
|
Term
|
Definition
| a central, or root node is connected to one or more second-level nodes, which in turn connect to other nodes at lower levels |
|
|
Term
|
Definition
| has characteristics of more than one standard topology |
|
|
Term
| physical star bus topology |
|
Definition
| link the central nodes of two or more star networks using a common network cable, or bus. each star network then becomes a sub-network, and is a node on a larger bus network |
|
|
Term
| physical star-of-star topology |
|
Definition
| you connect the central nodes of two or more star networks with a new common node |
|
|
Term
| physical star-ring topology |
|
Definition
| connect the central nodes of multiple star networks in a ring. the data flows between different sub-networks passes through this ring |
|
|
Term
| physical point-to point connection |
|
Definition
| a direct connection in which one node transmits data directly to a specific device |
|
|
Term
| physical multipoint connection |
|
Definition
| links multiple nodes on a network. so each multipoint has more than two endpoints |
|
|
Term
| physical Wi-Fi connections |
|
Definition
| enable users to move from place to place freely because devices don't have to be within line of sight of an access point |
|
|
Term
| physical radiated, or broadcast, connection |
|
Definition
| type of wireless point-to-point or multipoint connection between devices |
|
|
Term
|
Definition
| all nodes receive the data that's transmitted at the same time, regardless of the layout of physical wiring |
|
|
Term
|
Definition
| each node received data only from its upstream neighbor and retransmits data only to its down stream neighbor, regardless of the physical layout of wiring |
|
|
Term
|
Definition
| all nodes are wired onto the same bus cable, but a central device polls each node to check if it needs to transmit data |
