Classes of computers

Computers can be classified, or typed, in many ways. Some common classifications of digital computers are summarized below. For others see Category:Classes of computers.

Amorphous computing

Amorphous computing refers to computational systems that use very large numbers of identical, parallel processors each having limited computational ability and local interactions. The term Amorphous Computing was coined at MIT in 1996 in a paper entitled "Amorphous Computing Manifesto" by Abelson, Knight, Sussman, et al. Examples of naturally occurring amorphous computations can be found in many fields, such as: developmental biology the development of multicellular organisms from a single cell, molecular biology the organization of sub-cellular compartments and intra-cell signaling, neura ...

Barebone computer

A barebone computer is a partially assembled platform or an unassembled kit of computer parts allowing more customization and lower costs than a retail computer system. They are available for desktop computer, notebook and server purposes, and in nearly any form factor. Manufacturers are also able to produce systems of a specialized or non-standard form factor, since the system is sold as a pre-built unit, with the motherboard and power supply already installed.

Blitzen (computer)

The Blitzen was a miniaturized SIMD computer system designed for NASA in the late 1980s by a team of researchers at Duke University, North Carolina State University and the Microelectronics Center of North Carolina. The Blitzen was composed of a control unit and a set of simple processors connected in a grid topology. The machine influenced, to some extent, the design of the MasPar MP-1 computer. Applications of the Blitzen machine include high-speed image processing, where each processor operates on a pixel of the input image and communicates with its grid neighbours to apply image proces ...

Complex instruction set computer

A complex instruction set computer is a computer in which single instructions can execute several low-level operations or are capable of multi-step operations or addressing modes within single instructions. The term was retroactively coined in contrast to reduced instruction set computer and has therefore become something of an umbrella term for everything that is not RISC, from large and complex mainframe computers to simplistic microcontrollers where memory load and store operations are not separated from arithmetic instructions. A modern RISC processor can therefore be much more complex ...

Decimal computer

Decimal computers are computers which can represent numbers and addresses in decimal as well as providing instructions to operate on those numbers and addresses directly in decimal, without conversion to a pure binary representation. Some also had a variable wordlength, which enabled operations on numbers with a large number of digits.
