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]

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 ...
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 ...
ENIAC was a large, modular computer, composed of individual panels to perform different functions. Twenty of these modules were accumulators that could not only add and subtract, but hold a ten-digit decimal number in memory. Numbers were passed between these units across several general-purpose buses (or trays, as they were called). In order ...
For example, the 1961 Semiconductor Network Computer (Molecular Electronic Computer, Mol-E-Com), [10] [11] [12] the first monolithic integrated circuit [13] [14] [15] general purpose computer (built for demonstration purposes, programmed to simulate a desk calculator) was built by Texas Instruments for the US Air Force.
It meets most definitions of "mini" in terms of power and size, but was designed and built to be used as an instrumentation system in labs, not as a general-purpose computer. [11] Many similar examples of small special-purpose machines exist from the early 1960s, including the UK Ferranti Argus and Soviet UM-1NKh.
It uses more than 14,000 Xeon general-purpose processors and more than 7,000 Nvidia Tesla general-purpose graphics processing units (GPGPUs) on about 3,500 blades. [53] It has 112 computer cabinets and 262 terabytes of distributed memory; 2 petabytes of disk storage is implemented via Lustre clustered files.
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.
