^ dude obviously haven't been in the internet for a long time.
pretty sure you didn't google stuff you don't know about before yourself, don't you?
I started doing it all the time when I kept getting told to. I still ask questions if I don't understand, but that comes after looking up some information.
It's actually not easier to google something like this. Given that my knowledge in this area is practically nonexistent, if I googled this I'm liable to get a copious amount of results that I wouldn't be able to understand. (It would be like if I told you google post-structuralism.) I didn't even know what FTP was until a few hours ago. What I need is someone with very specific knowledge to answer this question in an easy to understand and non-complicated way. So, if you're interested in answering the question I'm thankful for your help, otherwise you're simply being a nuisance.
At least make an attempt, that's all I'm saying. It's completely understandable if you look up the term and don't understand it because of lack of knowledge. Asking for an explanation without trying to look it up yourself first is another story.
SFTP = Secure FTP. It's just another protocol that utilizes SSH.
SSH = secure shell. Basically a way to connect to a system with 128-bit encryption.
Read about
tunneling in addition to Lupin's links.
Look into Filezilla as well if you're interested in using SFTP.
Wikipedia makes for great reading when you want to learn about a subject (be ready to spend an hour or more).
