What are Mainframes?
Mainframes are very large computers that are built to be able to perform complex and critical applications. Mainframes are usually very large in both physical size and computational ability. They can be some of the largest machines on the planet. However, given the continued drive toward greater computational muscle in a smaller physical package, many mainframes are not too much larger than desktop computers these days. Mainframes are designed to keep running with as little interruption as possible. They contain large numbers of self-maintenance features, including built-in security features and backup power supplies. Since mainframes are usually the most important computers in a company’s computational arsenal, they are routinely protected by multiple layers of security and power backup, both internal and external. Among the self-protection measures commonly found in mainframes are an enhanced heat-protection mechanism. Since these computers run all day every day for years at a time,
