The same is true of the definitions themselves. These entries are usually workable, although seldom different than those you would find in any other basic computer dictionary. Overall, this appears to build on the common glossaries that used to be handed out as promotional pieces, and adds listings for more recent Internet jargon and newer protocols. This is done, but not very often. Some of the entry choices are odd.
Definitions are frequently incomplete at best, and sometimes so vague as to be misleading.
These definitions are obviously taking the company's word for it, rather than doing real research, and tend to be unreliable. The use of acronyms is inconsistent. Most of the time the reader is referred to the expanded term, regardless of how arcane it is. Cross-references between items are inconsistent at best. The carelessness in references and terms extends to capitalization, as well.
