An IBM mainframe is a large, high performance computer made by International Business Machines (IBM). Mainframe computers traditionally are "expensive,"The acquisition price of one mainframe is higher than, say, one PC. However, that's a bit like saying the acquisition price of a train freight car is higher than the price of a bicycle basket. Both can move goods, but there the similarity ends, and the costs depend almost entirely on the tasks required of them. Mainframes reduce labor costs, software costs, and costs of outage, among other costs, because they are systems designed to achieve significant economies of scale. individually physically largeNowadays, because mainframes consolidate scores or even hundreds of otherwise individual servers, they consume less electricity and occupy less space than equivalent workloads executing on individual servers. Most 21st century data centers require much more space for distributed servers than for mainframes., and have high transaction processing and I/O performance, but are not as expensive and high performanceIn single computational task terms. Weather modeling, protein folding analysis, nuclear explosion simulation, digital cinematography, and structural engineering analysis are examples of computational problems better suited to supercomputers. Mainframes are optimized for business transaction processing and large online database management, among other tasks. as supercomputers.
