I got to do a paper for a course of mine (about 45 pages long) on remote access and I am just looking for the divisions of this topic in SW and in HW. For example I already know that for a basic dial up remote access to my pc, I need at least Windows 98 with TCP/IP and at least a 14,400 modem. But what about situations where you need more bandwidth or more connections (like a company hasving sub-dvisions all over the world and needing them all to connect on a unified network). I have been told of a protocol called RADIUS and I would also like to know what that is (be brief guys, I am supposed to do the research :P).
Thanks in advance
