2.3 TRANSMISSION IMPAIRMENTS

2. DATA TRANSMISSION
• Data transmission is a process of sending digital and
analog data over a acommunication medium to one
more computing network.
• Sending and receiving data via cables

3. The successful transmission of data depends principally n two
factors;
• Quality of the signal being transmitted
• The characteristics of the transmission medium ( Bandwith,
cost, ease of installatio, etc…)

4. Concepts and Terminologies
Data transmission and terminologies occurs between transmitter and
receiver over some transmission medium.

6. Direct link used to refer to the transmission path between two
devices in which signals propagate directly from transmitter to receiver
with no intermediate devices , other than amplifiers or repeaters used
to increase signal strength.
This term can apply to both guided and unguided media.

7. Multipoint guided configuration , more than two devices share the
same medium.
