ABSTRACT
This book introduces the basic concepts of connecting
computers together and provides technical background necessary for
constructing small networks. For those already experienced with creating and
maintaining computer networks, the book is intended to encourage the creation
of a school-wide network. The book is divided into two main sections: an
introduction to networking in schools (6 chapters) and an introduction to the
technical side of networking (10 chapters). The chapter headings are as
follows:
"How Can Networking Enhance the Use of Computers?";
(1)
(2)
"Advanced Networking Concepts";
"Why Network Classroom Computers?";
(3)
(4)
"Why Network Computers for Administration?";
"Why Consider School-Wide
(5)
