Each assembly language is specific to a particular computer architecture, in contrast to most high-level programming languages, which are generally portable across multiple systems.

The characteristic which distinguishes one register as being the accumulator of a computer architecture is that the accumulator ( if the architecture were to have one ) would be used as an implicit operand for arithmetic instructions.

By the mid 1960s, binary addressing had become the standard architecture in most computer designs, and main memory sizes were most commonly powers of two.

* Burroughs collaborated with University of Illinois on a multiprocessor architecture developing the ILLIAC IV computer in the early 1960s.

In 1964 IBM introduced its System / 360 computer architecture which was used in a series of computers that could run the same programs with different speed and performance.

The System / 360 architecture was so popular that it dominated the mainframe computer market for decades and left a legacy that is still continued by similar modern computers like the IBM zSeries.

In the most commonly used computer architecture, the CPU consists of two main parts: Control Unit and Arithmetic Logic Unit ( ALU ).

This last term (" von Neumann machine ") is less specific and also refers to a completely unrelated computer architecture proposed by von Neumann, so its use is discouraged where accuracy is important.

In computer architecture, a bus is a subsystem that transfers data between components inside a computer, or between computers.

A design pattern in architecture and computer science is a formal way of documenting a solution to a design problem in a particular field of expertise.

The idea was introduced by the architect Christopher Alexander in the field of architecture and has been adapted for various other disciplines, including computer science.

Alpha, originally known as Alpha AXP, is a 64-bit reduced instruction set computer ( RISC ) instruction set architecture ( ISA ) developed by Digital Equipment Corporation ( DEC ), designed to replace the 32-bit VAX complex instruction set computer ( CISC ) ISA and its implementations.

DEC management doubted the need to produce a new computer architecture to replace their existing VAX and DECstation lines, and eventually ended the PRISM project in 1988.

Another popular computer architecture that utilizes the 6U-160 Eurocard is CompactPCI and CompactPCI Express.

He worked on the architecture of the IBM 7030 Stretch, a $ 10m scientific supercomputer of which nine were sold, and the IBM 7950 Harvest computer for the National Security Agency.

During this time he coined the term computer architecture.

* Guggenheim Fellowship for studies on computer architecture and human factors of computer systems, Cambridge University, England ( 1975 )

The history of stored-program computers relates first to computer architecture, that is, the organization of the units to perform input and output, to store data and to operate as an integrated mechanism.

* Harvard architecture, a type of computer architecture

For this step the computer memory is separated into three regions: cells in the W-region are used for storage of the forms in the text-form list ; ;

A new computer program is used to create the most comfortable and useful prosthetics.

Programming languages are primarily intended for expressing algorithms in a form that can be executed by a computer, but are often used as a way to define or document algorithms.

* 16: 10 = 1. 6 ( not shown above ): Widely used widescreen computer displays ( WXGA )

* Finite element analysis – a computer simulation technique used in engineering analysis

Competing machines such as the Altair 8800 generally were programmed with front-mounted toggle switches and used indicator lights ( red LEDs, most commonly ) for output, and had to be extended with separate hardware to allow connection to a computer terminal or a teletypewriter machine.

The computer was brought to Polytechnic University of Turin where it was fixed and used to run the BASIC programming language .</ li >

ALGOL ( short for ALGOrithmic Language ) is a family of imperative computer programming languages originally developed in the mid 1950s which greatly influenced many other languages and was the standard method for algorithm description used by the ACM, in textbooks, and academic works for the next 30 years and more.

For example, compositing is used extensively when combining computer rendered image elements with live footage.

The term is also used, especially in the description of algorithms, to mean associative array or " abstract array ", a theoretical computer science model ( an abstract data type or ADT ) intended to capture the essential properties of arrays.

They are used in order for the agent in the call center to confirm the phone the customer is calling from, so that a computer can automatically display the customer's account on a " screen pop " for the next available customer service representative ; they are distinct from purpose-made toll-free ANAC numbers.

Typically, these approaches follow a machine learning approach, where large numbers of manually rated photographs are used to " teach " a computer about what visual properties are of relevance to aesthetic quality.

The Aster computer could use the software written for the popular Tandy TRS-80 computer while fixing many of the problems of that computer, but it could also run CP / M software, with a big amount of free memory ( Transient Program Area, TPA ) and a full 80 × 25 display, and it could be used as a Videotext terminal.

Because the original designer had left the company another employee completely redesigned most of the system, ( adding a display snow remover circuit, true 80 / 64 column text mode support, ( with different size letters for TRS-80 and CP / M mode, so that in TRS-80 mode the full screen was also used, not just a 64x16 portion of the 80x25 screen ) with an improved font set ( adding " gray scale " version of the TRS-80 mozaik graphics and many special PETSCII like characters ), and a more flexible and reliable floppy disk controller and keyboard interface plus many other small improvements ), also an enclosure was developed for the main computer system, ( in the form of a 19-inch rack for the Eurocards ) and for two floppy disk drives and the power supply.

Amdahl's law, also known as Amdahl's argument, is named after computer architect Gene Amdahl, and is used to find the maximum expected improvement to an overall system when only part of the system is improved.

The Norden bombsight was a highly sophisticated optical / mechanical analog computer used by the United States Army Air Force during World War II, the Korean War, and the Vietnam War to aid the pilot of a bomber aircraft in dropping bomb s accurately.

* Alternating Turing machine, model of computation used in theoretical computer science

This might sound complex, but first of all the number of di-atomic molecules that can exist at the temperatures of the atomizers used in AAS is relatively small, and second, the correction is performed by the computer within a few seconds.

Finally, dropping prices of home computers like the Commodore 64 had caused many to believe that buying a home computer was a better investment because it provided more detailed gameplay and could be used for other purposes such as word processing.

Akihabara is a major shopping area for electronic, computer, anime, and otaku goods, including new and used items.

* 1991: Sofmap begins its rise as a major seller of new and used Japan-market computer parts and software, including popular systems from NEC ( PC-8801 and 9801 ), Sharp ( X68000 ) and Fujitsu ( FM-Towns ).

The encoding of data by discrete bits was used in the punched cards invented by Basile Bouchon and Jean-Baptiste Falcon ( 1732 ), developed by Joseph Marie Jacquard ( 1804 ), and later adopted by Semen Korsakov, Charles Babbage, Hermann Hollerith, and early computer manufacturers like IBM.
