The Dictionary of PC Hardware and Data Communications Terms covers terms in two of the most volatile and interesting areas of computer development: personal computers and networks. To create this comprehensive dictionary, the author combed the Internet and other online services to find the latest and most vexing acronyms and terms. It contains up-to-date information about everything from a common item like "batteries" to an obscure font technology called "Speedo." In a way it's inaccurate to call this a dictionary because it provides detailed, useful descriptions of complex terms. For example, the description of PGP (Pretty Good Privacy), a popular data encryption protocol, covers three and one-half pages. The entry for PowerPC contains a table listing the clock speed, transistors, width in bits, cache in kilobytes, and pins of each PowerPC processor currently in use. Terms are carefully cross-referenced as well.
