Reliance Jio Computer Communications Quiz-1

teleprocessing combing telecommunication and DP techniques in online activities.

Multiplexers are designed to accept data from several I/O devices and transmit a unified stream of data on one communication line.

a half-duplex line is a communication line in which data can move in two directions, but not the same time

batch processing is the preferred processing mode for telecommunication operations.

use a higher frequency for reception of radiation from earth stations and lower frequency for transmission to earth stations.

use lower frequency reception of radiation from earth stations and higher frequency for transmission to earth stations.

use a single frequency for reception and transmission from one point on earth to another

are devices that echo the radiation without change from one point on earth to another

has no effect on equipment

occurs when a DTE has no data transmit

is compensated for by the transmission of intentional bipolar violations to maintain equipment clocking.

occurs only after 9 p.m.

that represents the maximum rate that technology supports.

this rate allows unique values.

this rate allows the faithful recon-traction of an analog signal.

this rate is easily produced by a sampling chip

bipolar signaling produces twice as many marks as a unipolar signal.

it allows transmission at polar locations.

bipolar signaling reduces residual DC voltage buildup, allowing a digital signal to be separated from power through the use of a transformer.

it allows transformers to be spaced far from one another, which reduces the cost of transmission.

one or more conductors that serve as a common connection for a related group a device.

a continuous frequency capable of being modulated or impressed with a second signal

the condition when two or more sections attempt to use the same channel at the same time.

a collection of interconnected functional units that provides a data communications service among stations attached to the network
