Transmission Control Protocol/Internet Protocol
|
an industry standard suite of communication protocols. (allows the linking of devices running on many different platforms)
|
|
|
Packet
|
a collection of binary digits, including message data and control characters for formatting and transmitting, sent from computer to computer over a network.
|
|
|
Routing
|
process of deciding which path that data takes. (a packets route can change each time a connection is made, based on the amount of traffic and the availability of the circuit.
|
|
|
Routing Table
|
is used to determine the best possible route for the packet. (it lists nodes on a network and the path to each node, along with alternate routes and the speed of existing routes.
|
|
|
Centralized Routing
|
one node is in charge of selecting the path for all packets. (it stores the routing table, and any changes to a route must be made at this node.
|
|
|
Distributed Routing
|
relies on each node to calculate the best possible route. (each node contains its own routing table with current information on the status of adjacent nodes so that the best possible route can be followed)
|
|
|
Routers
|
a network connection device containing software that connects network systems and controls traffic flow between them.
|
|
|
Static Router
|
requires the network routing manager to give it information about which addresses are on which network
|
|
|
Dynamic Router
|
can build tables that identify addresses on each network. (used more often now, particularly on the internet.)
|
|
|
Client/Server Model
|
software runs on the local computer (the client) and communicates with the remote server to request information or services. (server is remote computer on the network that provides info or service in response to client requests.
|
|
|
Two-Tier Architecture
|
known as the traditional client/server model, a client (tier on) communicates directly with the server (tier two).
|
|
|
n-tier architecture
|
attempts to balance the workload between client and server by removing application processing from both the client and server and placing it on a middle-tier server.
|
|
|
Wireless Network
|
is a network that uses wireless instead of wired technology.
|
|
|
Mobile Network
|
(also called a cellular network) is a network operating on a radio frequency (RF), consisting of radio cells, each served by a fixed transmitter, known as a cell site or base station.
|
|
|
Throughput
|
is similar to bandwidth. It's the amount of data transferred or processed in a specified time, usually one second.
|
|
|
Time Division Multiple Access (TDMA)
|
divides each channel into six time slots. each user is allocated two slots: one for transmission and one for reception. this method increases efficiency by 300%, as it allows carrying three calls on one channel.
|
|
|
Code Division Multiple Access (CDMA)
|
transmits multiple encoded messages over a wide frequency and then decodes them at the receiving end.
|
|
|
Convergence
|
refers to integrating voice, video, and data so that multimedia information can be used for decision making
|
