I'll try to include them. In the meantime, I'm just coming up with a bunch off the top of my head. I would like to edit this page to add the technical term "SSD", but I cannot get past R in the edit function :You probably can't edit past the 32K limit. You might try editing a subsection with the edit link on the right side of the page at each individual subsection. I've been thinking about breaking this article up, but it should be done carefully to mesh with some of the already existing articles, without scattering the content here to the winds. :I've added SSD on your behalf. It still needs a real article, though. ==Ooops=== I'm sorry, I messed up the page several times today. I clicked save when I should have clicked 'preview'. I take the blame :-( See other meanings of words starting from letter: LLA | LB | LC | LD | LE | LF | LG | LH | LI | LJ | LK | LM | LN | LO | LP | LR | LS | LT | LU | LW | LX | LY | LZ |Words begining with List_of_computing_and_IT_abbreviations: List_of_computing_and_IT_abbreviations List_of_computing_and_IT_abbreviations |
