A. 1 Definition of Terms
(1) Communication type
(a) Simplex
This is the communication type that data is transferred in a constant direction. Information can not be transferred in the reverse
direction.
(b) Half-Duplex
Data is transferred in two ways with one cable if time interval provided, though it can’t be transferred simultaneously.
(c) Full-Duplex
Data is simultaneously transferred and received in two ways with two cables.
(2) Transmission type
This is divided into the following 2 types in consideration of the speed, safety and economy on transmission in binary (bit
composed of 0 and 1).
(a) Serial transmission
This type transmits bit by bit via 1 cable. The speed of transmission is slow, but the cost of installation is low and the software
is simplified.
