bits
|
binary-coded digital signals
|
|
|
IP
|
Internet Protocol - The most common internetwork protocol. IP is responsible for taking the formatted segments from TCP, encapsulating them into packets, assigning the appropriate addresses, and selecting the best path to the destination host.
|
|
|
TCP
|
Transmission Control Protocol - TCP is the transport portocol that manages the individual conversations between hosts. It divides messages into smaller pieces, called segments, to be sent to the destination client. It is also responsible for controling the size and rate at which messages are exchanged between the hosts.

Instant message protocols
|
XMPP (Extensible Messaging and Presence Protocol) and OSCAR (Open System for Communication in Realtime)
|
|
|
Converged network
|
coming-together of different technologies into one platform
|
|
|
Fault tolerance
|
continues to function normally even when some of the components of the network fail
|
|
|
Redundancy
|
duplication of equipment and media
|
|
|
Scalability
|
ability to grow and react to future changes
|
|
|
Quality of service
|
performance level offered through the network; also: the mechanisms that manage congested network traffic
|
|
|
circuit-switched, connection-oriented networks
|
temporary physical circuit was set up for communication; communication ended when physical circuit was disconnected; only one call per circuit; no simultaneous calls; vulnerable to easy disruption
|
|
|
packet-switched, connectionless networks
|
a single message is broken into packets; the packets travel through one or more networks and reassemble at the destination; packets travel independently of each other; does not require an active connection for the message to go through; multiple users can use networks simultaneously; if one network fails, another can deliver the entire message
|
|
|
bandwidth
|
data-carrying capacity of a network
|
