- 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.
