All those abbreviations (shortenings as I name them) drive me crazy

Hi, Abbreviations are for use on experienced personnel only. It is designed to save time and space. Sometimes, for general use, the full words is often placed first and the first letters of the words enclosed in parenthesis to denote its meaning. The contextual meaning of the letters are then understood throughout the paragraph or document. Sometimes I do get lost in it, having not made my homework or having missed the basics. So I made it a point to do research on it. It required in my line of work as a computer technician to know the meaning of those letters in order to understand the system and how to trouble shoot it. As a rule, every good writer should minimize the use of it, if it is not possible, it is always proper to spell them out. In computer usage, it is necessary to save space, like in accessing the Basic Input-Output System (BIOS) in the Complementary Metal Oxide Simeconductor (CMOS). All the instructions there that we see are all abbreviated and it would take a while to learn them all, much more how they interact with one another, their functions and the effects when we alter their values.
