A disk operating system (DOS) is a computer operating system that resides on and can use a disk storage device, such as a floppy disk, hard disk drive, or optical disc. A disk operating system provides a file system for organizing, reading, and writing files on the storage disk, and a means for loading and running programs stored on that disk. Strictly, this definition does not include any other functionality, so it does not apply to more complex OSes, such as Microsoft Windows, and is more appropriately used only for older generations of operating systems.
A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing. A mainframe computer is large but not as large as a supercomputer and has more processing power than some other classes of computers, such as minicomputers, servers, workstations, and personal computers. Most large-scale computer-system architectures were established in the 1960s, but they continue to evolve. Mainframe computers are often used as servers.

The Elea was a series of mainframe computers Olivetti developed starting in the late 1950s. The system, made entirely with transistors for high performance, was conceived, designed and developed by a small group of researchers led by Mario Tchou (1924–1961), with industrial design by Ettore Sottsass. The ELEA 9001 was the first solid-state computer designed and manufactured in Italy. The acronym ELEA stood for Elaboratore Elettronico Aritmetico and was chosen with reference to the ancient Greek colony of Elea, home of the Eleatic school of philosophy. About forty units were placed with customers. In August 1964, only a few years after releasing the 9003, Olivetti's mainframe business was sold to GE.
