Data communication involves the transmission of electronic data over a transmission medium. It has five basic components: a sender, receiver, message, medium, and protocol. There are different modes of transmission including simplex, half duplex, and full duplex. The transmission medium is the physical path between the transmitter and receiver, which can be guided mediums like twisted pair cables or unguided mediums like microwaves. It carries the encoded data signals in the form of electromagnetic or light waves.

5. Data Communication
 Transmission of electronic data over
some media.
 Media may be cables or microwaves
 Electromagnetic or light waves that
transfer in encoded form are called
signals.
 Two types of signals – Analog & Digital

6. Components
 Fives basic elements are needed for any
communication.
 Sender – device that is used for sending data
 Receiver – device that receives the data
 Message – data that is sent through medium
 Medium – through which data is send
 Protocol– rules under which data transmission
takes place between sender and receiver.

8. Modes Of Transmission
 Manners in which data is transmitted
from one location to another
 There are three types of transmission
mode
 Simplex, Half Duplex and Full Duplex

10. Transmission Medium
 Physical path between transmitter and
receiver
 Data is transmitted through electrical or
electromagnetic signals
 Two types of Medium- Guided and
Unguided Medium
 Twisted pair cable, Coaxial cable &
Fiber optics cable
