The funny thing about the Internet is that it has been around for a lot longer than you probably realize. Most people would tell you the Internet came into being some time during the Nineties and, indeed, that is when it first started to reach the general public and become the all-pervading force we know it as today. However, the history of the Internet dates back a lot further -- in fact, all the way back to the 1960s when mainframes were still relatively new.

Despite the rise in prominence of high-end Unix and Intel-based servers, as well as the rise of the personal computing and cloud computing, mainframes are as relevant as ever in the year 2011. In this article, we'll take a look at some of the reasons behind this, such as terminal emulation software, as well as some of the biggest challenges facing mainframes.
