The GM-NAA I/O input/output system of General Motors and North American Aviation was the first operating system for the IBM 704 computer. [1] [2] It was created in 1956 by Robert L. Patrick of General Motors Research and Owen Mock of North American Aviation. [1] It was based on a system monitor created in 1955 by programmers of General Motors ...
IBM 7151 Console Control Unit for 7090. The IBM 7090 is a second-generation transistorized version of the earlier IBM 709 vacuum tube mainframe computer that was designed for "large-scale scientific and technological applications".
This feature added five operation codes and was needed as a buffer for tape and disk I/O. The 60 words could also be used by programs to speed up inner loops and table lookups. Three four-digit index registers at addresses 8005 to 8007; drum addresses were indexed by adding 2000, 4000 or 6000 to them, core addresses were indexed by adding 0200 ...
Roughly every decade, technology advances in semiconductors, storage, networks, and interfaces enable the emergence of a new, lower-cost computer class (aka "platform") to serve a new need that is enabled by smaller devices (e.g. more transistors per chip, less expensive storage, displays, i/o, network, and unique interface to people or some ...
By 1957, EDVAC was running over 20 hours a day with error-free run time averaging 8 hours. EDVAC received a number of upgrades including punch-card I/O in 1954, extra memory in slower magnetic drum form in 1955, and a floating-point arithmetic unit in 1958. EDVAC ran until 1962 [11] when it was replaced by BRLESC.
The die from an Intel 8742, an 8-bit microcontroller that includes a CPU running at 12 MHz, RAM, EPROM, and I/O While the earliest microprocessor ICs literally contained only the processor, i.e. the central processing unit, of a computer, their progressive development naturally led to chips containing most or all of the internal electronic ...
I/O is the means by which a computer exchanges information with the outside world. [125] Devices that provide input or output to the computer are called peripherals . [ 126 ] On a typical personal computer, peripherals include input devices like the keyboard and mouse , and output devices such as the display and printer .
The UNIVAC III, designed as an improved transistorized replacement for the vacuum tube UNIVAC I and UNIVAC II computers. The project was started by the Philadelphia division of Remington Rand UNIVAC in 1958 [1] with the initial announcement of the system been made in the Spring of 1960, [1] however as this division was heavily focused on the UNIVAC LARC project the shipment of the system was ...
