As a network engineer you must have skimmed through millions of acronyms and abbreviations like MAC, IP, FTP, ….. and so on, they are un-countable :D. Sometimes these abbreviations mix them into a cocktail in my head, so Today I thought of re-visiting some of these abbreviations and concepts that I consider fairly important if you are considering to understand switching. So let’s start of by defining each one of these abbreviations.
“IP telephony is the Concept, VoIP is the Use” I believe this quote can serves as an answer to the Big Question, but what does this really mean ?.

Examples of an IP telephony system include and IP Public Private Exchange (PBX).
Also this might be very easy to do, I always seem to forget it =D. Anyway, here is how: you just type cat etc/lsb-release on your terminal. That’s it =). I hope this helps, Have a good day!!

Long time I had this question in my head, why do we subnet, yea I am being a smart guy, I am very good at sub-netting but I didn’t know why it is so crucial. Well there are many answers to that question, the most general ones are: Reduced network traffic Optimized network performance Simplified management Facilitated spanning of large geographical distances. Okay, that’s cool but still, How does it do these “bla bla written above” =D ?
