DATA COMMUNICATION
NETWORKING
DATA COMMUNICATION
• refers to the active process of transmitting data or
information from one point to another through a
medium.
• There are five components of data communication.
FIVE COMPONENTS OF DATA
COMMUNICATION
• Transmitter
• Receiver
• Medium
• Message
• Protocol
TRANSMITTER
• The transmitter is the device that sends the message.
It can be a computer, workstation, telephone handset,
video camera, and so on.
RECEIVER
• The receiver is the device that receives the message. It
can be a computer, workstation, telephone handset,
television, and so on.
MEDIUM
• The transmission medium is the physical path by
which a message travels from sender to receiver. It
can consist of twisted pair wire, coaxial cable, fiber-
optic cable, laser or radio waves (terrestrial or satellite
microwave).
MESSAGE
• The message is the transmission (data) to be
communicated. It can consist of text, number,
pictures, sound, or video or any combination of these.
PROTOCOL
• A protocol is a set of rules that governs data
communication. It represents an agreement between
the communicating devices. Without a protocol, two
devices may be connected but not communicating.
DATA TRANSMISSION
DATA
REPRESENTATION
• Anything that can have two
different states can
represent anything on a
digital device.
• Most computer are digital
• Recognize only two discrete
states: on and off.
• Use binary system to recognize 2
states
• Use number system with 2
unique digits: 0 and 1 called bits
( binary digits).
HOW DO COMPUTERS
REPRESENT DATA?
DATA FLOW
• The route between origin, via nodes, to a destination
taken by a packet of data.
• The transfer of data between the components of a
computer.
• The path taken by the message from origination to
destination that includes all nodes through which the
data travels.
3 WAYS TO TRANSMIT DATA
• Simplex
• Half- duplex (HDX)
• Full- duplex (FDX)
SIMPLEX
• Is one way transmission, it uses one circuit in one
direction only such as in radio or TV transmission. It is
simple and relatively inexpensive.
HALF – DUPLEX (HDX)
• Is two-way transmission and it also use only one
circuit as simplex does but it is used in both
directions, walkie-talkie is the good example of the
half-duplex processor. Half duplex is a circuit, which
can transmit the signal in two directions but only once
at a time. In Half-duplex users can transmit and
receive signals or data but cannot do both
simultaneously.
FULL – DUPLEX (FDX)
• Full duplex transmission is also the two-way
transmission but it uses two circuits for
communication. Full duplex allows users to
communicate in both way simultaneously (i.e. a
common telephone) with no turnaround time. This
mode is clearly easier to use then the half duplex but
the cost may be significant, especially over long
distance.
