Unit 9: Simulation of a PERT Network (I)
Notes
Notes This is ideal because the fewer input bits you have, the easier it is to engineer the
network. Below is a modified version of ISO’s 6 bit character set.

The system now needs an object responsible for interpreting character data and distributing it to
the input controller. The diagram below illustrates how the input stream feeds data to the input
controller by converting the character data to binary channels.
Figure 9.2: Input Stream Working with the Network Input Controller
The output process works exactly the same way, but in reverse. The output stream converts the
binary input to character data.
