Almost every acronym or word used in IT is used for more than one purpose and has different meanings depending on who uses it.
I worked on Andersen's (now Accenture) case tool called Foundation and it called its runs "instances". Later when I started working on Oracle I found it called each database an "instance".
For years I knew "core" files to be memory core dumps from processes that had died. Later Oracle and others started using that as a directory name. (Which caused issues as many folks had cron jobs to delete "core" files periodically.)
I'm not picking on Oracle - just happens to be two examples of which I can think.
That is why often when posting/emailing a message I will first put the full name then follow it with the acronym or abbreviation in parentheses on first use within the post. e.g. Logical Volume (LV). Then when I use LV later in the post it should be clear I mean Logical Volume rather than lefthanded vertebrate as some zoologist that dabbles in Linux might think.
P.S. There's been many a post at LQ that I opened thinking I might be able to assist only to find the acronym or word they used in the title has nothing to do with what I thought when I saw that acronym or word.
