U$26.95/C$34.95
This is a readable and fairly comprehensive guide to the concepts and
terminology behind Local Area Networks. While it gives a thorough
background to a wide range of LAN features, technical details are
scant. This may be good news to the executive trying to get an
initial grasp of networking; it may present problems to the manager
charged with coming up with a plan for implementation.
Three initial chapters provide basic concepts and jargon for LANs,
basic parts and pieces, and connections to wide area networks. Four
major network operating systems are described in further chapters, and
it is nice to see some mention of OS/2 and Macintosh systems included.
Chapter eight is a bit odd: of the four "other" LANs listed, two are
hardware interfaces rather than network operating systems. A further
three chapters look at electronic mail options, management and
networkable software. The book closes with a chapter on LAN selection
and appendices with vendor addresses, a glossary and a bibliography.
The material is very basic and almost completely non-technical. The
content will certainly help a neophyte to get started, or someone who
has to "start from zero" on a major networking project. However, the
lack of technical details could allow for major disasters in the
choice of systems. For example, the topologies are described
correctly, but the load implications of the different access methods
are never discussed. An ethernet, with repeaters, could conceivably
service an entire ten-storied building. With heavy loads, however,
you would probably want to break that down into a series of smaller
networks with routing. If response time is critical, you probably
need token-ring access in order to guarantee an upper bound to
delays. (The lack of detail extends to the review questions at the
end of each chapter. These are extremely simple queries from the
lowest level of Bloom's Taxonomy, and only serve to check whether
you've read every sentence.)
A possibly useful start, but far from being complete.
