The U.S. military's SAGE system was the first large-scale example of such a system, which led to a number of special-purpose commercial systems such as Sabre. [140] In the 1970s, computer engineers at research institutions throughout the United States began to link their computers together using telecommunications technology.
The ABC pioneered important elements of modern computing, including binary arithmetic and electronic switching elements, [5] but its special-purpose nature and lack of a changeable, stored program distinguish it from modern computers. The computer was designated an IEEE Milestone in 1990. [6]
In 1977 Randell published an article The First Electronic Computer in several journals. [ g ] [ 79 ] In October 2000, a 500-page technical report on the Tunny cipher and its cryptanalysis—entitled General Report on Tunny [ 80 ] —was released by GCHQ to the national Public Record Office , and it contains a fascinating paean to Colossus by ...

The Blue Gene/P supercomputer "Intrepid" at Argonne National Laboratory (pictured 2007) runs 164,000 processor cores using normal data center air conditioning, grouped in 40 racks/cabinets connected ...
An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. [1] [2] It is embedded as part of a complete device often including electrical or electronic hardware and mechanical parts.
However, it was not a general-purpose computer, being able to only solve a system of linear equations, and was also not very reliable. The Colossus computer at Bletchley Park. During World War II, special-purpose vacuum-tube digital computers such as Colossus were used to break German machine (teleprinter) ciphers known as Fish. The military ...
The term computer remained one that referred to mostly women (now seen as "operator") until 1945, after which it took on the modern definition of machinery it presently holds. [ 44 ] The ENIAC (Electronic Numerical Integrator And Computer) was the first electronic general-purpose computer, announced to the public in 1946.
It is a special-purpose system for molecular dynamics (MD) simulations of proteins and other biological macromolecules. An Anton machine consists of a substantial number of application-specific integrated circuits (ASICs), interconnected by a specialized high-speed, three-dimensional torus network .
