DICTIONARY  

Dictionary of the Hardware - A/H


This is a very particular dictionary; as his name indicates, it will not find all the proper terms of the computer science, but "only" those that concern the hardware, especially the initials, of dark meaning, especially if the English language is not known.

Devices and devices appear not only, but also words that refer to protocols, norms, or very basic terms of the software or which relation with the hardware makes essential to know his meaning.

For his extension, it has split into 3 documents, including this one. To find a word:

  1. kitchen boy in the following table in the letter by which it starts for what he looks;
  2. move in vertical up to finding the word in question;
  3. pulsate in the button Behind of his navigator or go to the beginning or end of the page.
