Description: This chapter works with the next six chapters to act as a foundation for the technology discussions that
follow. In this chapter, some fundamental concepts and terms used in the evolving language of
internetworking are addressed. In the same way that this book provides a foundation for understanding
modern networking, this chapter summarizes some common themes presented throughout the remainder
of this book. Topics include flow control, error checking, and multiplexing, but this chapter focuses
mainly on mapping the Open System Interconnection (OSI) model to networking/internetworking
functions, and also summarizing the general nature of addressing schemes within the context
of the OSI model. The OSI model represents the building blocks for internetworks. Understanding the
conceptual model helps you understand the complex pieces that make up an internetwork. Platform: |

Description: In most modern engineering systems, there is a need to control the evolution with
time of one or more of the system variables. Controllers are required to ensure
satisfactory transient and steady-state behavior for these engineering systems. To
guarantee satisfactory performance in the presence of disturbances and model
uncertainty, most controllers in use today employ some form of negative feedback.
A sensor is needed to measure the controlled variable and compare its behavior
to a reference signal. Control action is based on an error signal defined as the
difference between the reference and the actual values. Platform: |
