  • Front
  • Back
De Facto
In reality or fact; actually.
Print server
provides access to shared printer
need access to resources such as files, appications, printers
Star Topolgy
A hub or repeater is in the center of the star. Circuitry in a hub can reproduce a bus, ring, or even mesh topology.

Most commonly used.
Peer-to-Peer Network
computers talk directly to each other; used mostly for home use because it is cheap; but can have security risks
n 1: (computer science) the time it takes for a specific block of data on a data track to rotate around to the read/write head [syn: rotational latency] 2: the time that elapses between a stimulus and the response to it [syn: reaction time, response time, latent period] 3: the state of being not yet evident or active

American National Standards Institute

US's voting member of the ISO and ITU-T and works with them to make US national standards
Network Operating System -

An operating system
which includes software to communicate with other computers
via a network. This allows resources such as files,
application programs, and printers to be shared between
Distributed Processing
Opposite of centralized; user has control of data and apps; IS has little control;
Novel Netware
Killer app for LANs
Metropolitan Area Network
Random variation in the timing of a signal, especially a
Active Network
Data transmitted over the network is passed from node-to-node and each node is responsible for transmitting the data to the next node on the ring.
provide resources to clients
Centralized Processing
users access through a "dumb" terminal; apps executed on a centrlized computer (mainframe); uses timesharing;
IS staff has a lof control; user has little or no control over data and apps
Campus area network
Communication Server
Provides access to shared communication devices such as modems or fax machines.
Application server
runs server based applications such as Web server. CPU predormance is usually critical.
Mesh Topology
Each computer is connected to every other computer.

Most releible and most expensive. Network can have a combination of mesh and star topology.
File Server
provides access to sever's file system allowing centralized storage of data and applications
Bus Topolgy
Single linear tranmission medium (bus). Nodes tap into the bus with a drop cable.

Must have terminator on each end so the bus.

Broadcast oriented - data sent by one node is receieved by all nodes.

Must be planned carefully and are hard to trouble shoot

Ring Topoly
each node is connected to 2 other nodes in a closed loop. Almost always "active".

Tings also have to be planned. A cable failure can bring down a network.
