Mainframe computers are often used as servers. The term mainframe was derived from the large cabinet, called a main frame, [2] that housed the central processing unit and main memory of early computers. [3] [4] Later, the term mainframe was used to distinguish high-end commercial computers from less powerful machines. [5]
The IBM 704 is the model name of a large digital mainframe computer introduced by IBM in 1954. Designed by John Backus and Gene Amdahl, it was the first mass-produced computer with hardware for floating-point arithmetic. [1] [2] The IBM 704 Manual of operation states: [3]
IBM 704 mainframe at NACA in 1957. From 1952 into the late 1960s, IBM manufactured and marketed several large computer models, known as the IBM 700/7000 series.The first-generation 700s were based on vacuum tubes, while the later, second-generation 7000s used transistors.
The IBM System/360 (S/360) is a family of mainframe computer systems announced by IBM on April 7, 1964, [1] and delivered between 1965 and 1978. [2] System/360 was the first family of computers designed to cover both commercial and scientific applications and a complete range of applications from small to large.
Ken Olsen, the MIT-educated inventor who started Digital Equipment Corp. with $70,000 in venture capital in the 1950s and built it into a company with billions of dollars in sales and more than ...
The IBM 701 was the first computer in the IBM 700/7000 series, which were IBM’s high-end computers until the arrival of the IBM System/360 in 1964. [5] The business-oriented sibling of the 701 was the IBM 702 and a lower-cost general-purpose sibling was the IBM 650, which gained fame as the first mass-produced computer. [4] [6]
International Business Machines (IBM) used to dominate the computer industry -- especially in the 1960s when mainframe computers were the only game in town. During the 1970s, that dominance gave ...
The first experimental system went live in 1960 and the system took over all booking functions in 1964 – in both cases using IBM 7090 mainframes. In the early 1960s IBM undertook similar projects for other airlines and soon decided to produce a single standard booking system, PARS , to run on System/360 computers.
