53 OTU RAF was an Operational Training Unit of the Royal Air Force. It was formed at RAF Heston in February 1941 to train Spitfire pilots for Fighter Command. [1] In July 1941 it moved to RAF Llandow in Wales, and in May 1943 to RAF Kirton-in-Lindsey in Lincolnshire. Pilots trained initially on Miles Master aircraft and later on Spitfires.
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
Hewlett Packard Enterprise Frontier, or OLCF-5, is the world's first exascale supercomputer. It is hosted at the Oak Ridge Leadership Computing Facility (OLCF) in Tennessee , United States and became operational in 2022.
A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.
The Squadron became a day fighter unit in 1940 and operated both the Hawker Hurricane and the Supermarine Spitfire. Aircrew attrition and transfers to other units, war quickly took its toll on the pre-war personnel and as replacements were drafted in from all walks of life and all parts of the Commonwealth to cover casualties and promotions ...
Launch of IBM System/360 – the first series of compatible computers, reversing and stopping the evolution of separate "business" and "scientific" machine architectures; all models used the same basic instruction set architecture and register sizes, in theory allowing programs to be migrated to more or less powerful models as needs changed.
The ETA10 is a vector supercomputer designed, manufactured, and marketed by ETA Systems, a spin-off division of Control Data Corporation (CDC). The ETA10 was an evolution of the CDC Cyber 205, which can trace its origins back to the CDC STAR-100, one of the first vector supercomputers to be developed. [1]
On 22 May 1948, over Israel, a unique incident took place in the Spitfire's operational history when three Spitfire users came into conflict. [200] On this date, five Egyptian Mk IXs attacked, by mistake, the RAF base at Ramat David, shared by 32 and 208 Squadrons. They destroyed a number of Mk XVIIIs on the ground, but the surviving Spitfires ...
