Abstract:
The simulation of the flight following system i6 primarily
chosen in the interest of Ethiopian Airlines need to implement
the system to replace the currently used flight following
system which is based on verbal communication between
aircraft and ground control people.
The first section of this paper discusses the components of
data communication system, aspects and objective of data
communication system.
The second section laid the emphasis on the fundamental communication
concepts parallel transmission, serial transmission
and the different types of serial transmission. The
theory behind the simulation is basically based on the different
types of transmission modes. The third section build
the foundation for the characteristics of data transmission,
direction of information flow: simplex, half-duplex and full
duplex and finally rate of transmiesion effect on data
transmission. In section 4 the different coding technology
and structures are presented.
A unique feature of the paper is section 5 protocol. There
are sections on identifying and defining a problem in data
communication specially for good understanding between a
sender and a receiver.
