    IBM zEnterprise and IBM 1401

    Date added: 15 Feb 2011

    IBM mainframe computers have provided the technology backbone for businesses requiring secure systems for processing massive amounts of data, which includes transactions from ATMs, medical records and stocks. Pictured below, the IBM 1401 -- introduced 1959 -- was one of the first computers to run completely on transistors, not vacuum tubes.
