A collection of computers and other hardware devices connected together.
Computer Network
Devices in a network are physically wired.
wired network.
Amount of data that can be transferred in a given period of time.
bandwidth.
Devices used to extend the range of a network by clearing out the electrical noise and broadcasting the message to all interconnecting devices.
Repeater
method of reducing data frame collision on a shared channel
Controlled Access Protocol
Indicates how devices are arranged in a network.
Physical topology
Device at the center of a LAN that runs at full duplex mode.
Switch.
Total bandwidth available in a communication medium is divided into a series of non-overlapping frequency bands, each of which is used to carry a separate signal.
FDM
method of flow control in which a sender can transmit the several frames before getting an acknowledgement.
Sliding Window Protocol
Star, Bus, Mesh
physical topologies.
framing, addressing, flow-control,error control and media control are related to
DataLink layer
Use networking technology to determine the current location or status of an object.
Monitoring Systems
Conventional t.v signals. Data is represented by continuous waves.
analog signals.
A passage to connect two networks that may work upon different networking models.
Gateway
Two or more bits are changed from 0 to 1 or from 1 to 0 is known as Burst Error.
Burst Error
Data uses a dedicated path from the sender to the recipient.
circuit switching networks.
Frequency of failure and the time it takes the link to recover from failure.
