Abbreviations and full forms related to Computers

As i am preparing for the IT quiz this week, i have been really busy in collecting and learning resources. At these time i found how hard it is, to get the correct resources from Google and other search engines, from the midst of spam sites. I had to spen a lot of time to find several resources like Computer / IT related abbreviations, Computer / IT related inventions ……etc. So I decided to make a post on it. As this blog has good SEO and rankings, i hope this could show up in the front pages of search engines and hope that this could be useful for someone.
