He was highly influential in the development of computer science, giving a formalisation of the concepts of " algorithm " and " computation " with the Turing machine, which can be considered a model of a general purpose computer.

In the field of computer graphics, an anisotropic surface will change in appearance as it is rotated about its geometric normal, as is the case with velvet.

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 high price was likely due to the rare documents and packaging offered in the sale in addition to the computer, including the original packaging ( with the return label showing Steve Jobs ' parents ' address, the original Apple Computer Inc ' headquarters ' being their garage ), a personally typed and signed letter from Jobs ( answering technical questions about the computer ), and the original invoice showing ' Steven ' as the salesman.

A January 15, 1941 story in the Des Moines Register announced the ABC as " an electrical computing machine " with more than 300 vacuum tubes that would " compute complicated algebraic equations " ( but gave no precise technical description of the computer ).

RWTH Aachen University, established as Polytechnicum in 1870, is one of the Germany's Universities of Excellence with strong emphasis on technological research, especially for electrical and mechanical engineering, computer sciences, physics, and chemistry.

Although early Commodore advertisements attempted to cast the computer as an all-purpose business machine, the Amiga was most commercially successful as a home computer, with a wide range of games and creative software.

In computer graphics, alpha compositing is the process of combining an image with a background to create the appearance of partial or full transparency.

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

As Wozniak was the only person who could answer most customer support questions about the computer, the company offered Apple I owners discounts and trade-ins for Apple IIs to persuade them to return their computers, contributing to their scarcity.

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.

APL ( named after the book A Programming Language ) is an interactive array-oriented language and integrated development environment, which is available from a number of commercial and noncommercial vendors and for most computer platforms .< ref >

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.

However, as this was essentially just a 65XE computer with a detachable keyboard, it was able to run most of the home computer titles directly.

Soon after, BBS software was being written for all of the major home computer systems of the late 1970s era-the Apple II, Atari, Commodore and TRS-80 being some of the most popular.

Bjarne Stroustrup (); born December 30, 1950 in Århus, Denmark ) is a Danish computer scientist, most notable for the creation and the development of the widely used C ++ programming language.

The most promising approaches treat the brain as a biological computer, very different in mechanism from electronic computers, but similar in the sense that it acquires information from the surrounding world, stores it, and processes it in a variety of ways.

It was during this period that a number of simple computer games were written in BASIC, most notably Mike Mayfield's Star Trek.

In the 1980s, companies had few people who understood the growing personal computer phenomenon, and so most technical people were given free rein to purchase whatever software they thought they needed.

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.

In computational complexity theory, BQP ( bounded error quantum polynomial time ) is the class of decision problems solvable by a quantum computer in polynomial time, with an error probability of at most 1 / 3 for all instances.

In computer science, a binary tree is a tree data structure in which each node has at most two child nodes, usually distinguished as " left " and " right ".

This was the first known computer and most advanced system of calculation known to date-preceding Greek methods by 2, 000 years.

While von Neumann is most often credited with the design of the stored-program computer because of his design of EDVAC, others before him, such as Konrad Zuse, had suggested and implemented similar ideas.
