Communication Networks
- Share to:
This book is concerned with post-computer communication networks and two of its
important streams: data communication and telecommunication. Data communication
refers to the communication between digital computers, facilitated by computer
networks. Telecommunication refers to the primarily human-to-human
communication facilitated by the global telephone system. The differences between
these two streams are mainly due to historical reasons. Telecommunication is
increasingly relying on digital computer technology, and data communication is relying
more than ever on telecommunication networks. The two streams are rapidly
converging.
Newcomers to this field are often bewildered by the substantial wealth of
information already published on the subject. This book is aimed at this group of
people. It provides a broad coverage of the key concepts, techniques, and
terminology, so as to prepare readers for more advanced discussions. In-depth
discussions of technically-involved topics are intentionally avoided in favor of more
general concepts. No previous knowledge of networks or programming is assumed.
The structure of the book is as follows. Chapter 1 introduces computer networks
and explains some of their elementary concepts. It also introduces the OSI reference
model, upon which later chapters are based. Each of Chapters 2-8 describes one of
the seven layers of the OSI model in the context of wide area data networks.
Chapter 9 looks at local area networks and their applications. Chapter 10 provides
an introduction to telecommunication. Chapter 11 builds on earlier chapters by
examining ISDN as the merging point of data and voice networks. Chapter 12 looks
at the ATM technology and the potential applications that it can support
