IBM mainframes are large computers that have been produced by the technology giant IBM since 1952. Their production of the mainframe computers saw IBM dominate the industry throughout the 60s and the 70s. IBM is still the major player in the industry today.
IBM mainframes have always been and still are huge when it comes to hardware size. It’s been one of their most telling characteristics with a single unit being larger than a refrigerator.
Computers used commonly in the modern era are a lot more compact than the IBM mainframes but they did not make the IBM mainframes become obsolete. One might think that such bulky hardware no longer has any use but that is far from the truth. In a time where data processing has become much faster and more efficient than what it used to be, IBM has maintained an edge over other manufacturers when it comes to producing ultra high performance data processing supercomputers.
IBM mainframes play a central role in the day-to-day operations of most of the largest corporations in the world. While other forms of computing are still extensively used in business operations, the IBM mainframes have their own place in the business environment serving various purposes. Every industry, including health, banking, finance and even governments consider IBM mainframes to be one of their foundations.
Until the 1990s, IBM mainframes processed large amounts of data for businesses. With steady and increasing technological advancements, IBM mainframes are now capable of running large and complex programs like general ledger processing and payroll generation software.
The primary operating systems used in the current IBM mainframes include z/OS, z/VM, z/VSE, z/TPF and Linux.
