What is DATA TRANSMISSION LINE


DATA TRANSMISSION LINE

data transmission line areas are used to transmitting data, the six transmission line is required .the quality of a transmission line depends upon transmission speed of the transmission line with higher speed is higher in quality,

DATA TRANSMISSION Speed

Data transmission capacity of a communication system (transmission lines are required. the quality of a transmission line depends upon transmission speed. the transmission line with higher speed is higher in a quality.

DATA TRANSMISSION

DATA handling capacity of a communication system(transmission line) is known its bandwidth is also known as baud rate. Other units to measure bandwidth are kbps, Mbps, etc.data transmission line are classified on the basis of bandwidth; they are:

NARROW BAND

these type of lines have lowest data transfer rate.
Its rate lies between 45 bps to 300bps that is why they are used in Networks
Which require a low amount of data. these types of lines are mainly for telegraph line and low-speed terminals.


Voiceband

These types of lines have grate transmission speed as compared to NARROW BAND line. It can transmit data at speed up to 9600 bps.their major applications is ordinary telephone line voice communications that is why they are called voice band lines. Most of the remote terminals are connected through voiceband channels.

WIDEBAND  LINE(Broad Band):

These lines are used to transmitting the very large volume of data .their data handling capacity is highest i.e.,1 million(10to6)bps or more these lines are now replacing voice band in almost every area of communication .they are used in mobile devices such as cellular phone, laptop, notebook, etc.
