And if you don't know what PuTTY is, I really don't even consider you a networking person. In fact, PuTTY has been around for a long time, but it's been constantly updated.

I know it's hard to imagine that, without opening up a browser, you could do anything on the internet. In fact, I'm so old that I remember using the internet heavily long before there was anything called a World Wide Web or webpages or anything like that.
