We have reached, in our society and in our technology, the level of connectivity to where more and more people "work at home" and build entire businesses out of their home-based offices or studios. My wife calls this private workspace: "the Man Cave", after seeing it develop and come to be a place where I spend a great deal of my time, working, and learning, and growing in knowledge of technology.
I work with all of this in developing my computer skills, my networking skills, and becoming the best I can be at the various popular technologies like "VPN" (virtual private networks) or "Cloud Computing" (servers & resources "out there"), to be the best I can be at helping folks to "Get CONNECTED"! I work with LINUX, with UNIX, with Apple MAC's and OS/X, and even with Windows. I configure network routers, ISDN routers, switches, and work with UPS systems (power backup systems). I even have dial-up so I can work with UUCP (Unix-to-Unix Copy Program) and terminals in the multi-user UNIX and LINUX world.
