In human – computer interaction, computer accessibility ( also known as Accessible computing ) refers to the accessibility of a computer system to all people, regardless of disability or severity of impairment.

For general computer use access technology such as screen readers, screen magnifiers and refreshable Braille displays has been widely taken up along with standalone reading aids that integrate a scanner, optical character recognition ( OCR ) software, and speech software in a single machine.

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

It is worth mentioning that the Nepōhualtzintzin amounted to the rank from 10 to the 18 in floating point, which calculated stellar as well as infinitesimal amounts with absolute precision, meant that no round off was allowed, when translated into modern computer arithmetic.

The abacus shows how numbers, letters, and signs can be stored in a binary system on a computer, or via ASCII.

The beads represent a switch on the computer in either an ' on ' or ' off ' position.

* Argument ( computer science ), a piece of data provided as input to a subroutine

* ANIMAL, an early self-replicating computer program

With the development of fast Internet in the last part of the 20th century along with advances in computer controlled telescope mounts and CCD cameras ' Remote Telescope ' astronomy is now a viable means for amateur astronomers not aligned with major telescope facilities to partake in research and deep sky imaging.

In mathematics and computer science, an algorithm ( originating from al-Khwārizmī, the famous Persian mathematician Muḥammad ibn Mūsā al-Khwārizmī ) is a step-by-step procedure for calculations.

: Precise instructions ( in language understood by " the computer ") for a fast, efficient, " good " process that specifies the " moves " of " the computer " ( machine or human, equipped with the necessary internally contained information and capabilities ) to find, decode, and then process arbitrary input integers / symbols m and n, symbols + and =

Many computer programs contain algorithms that detail the specific instructions a computer should perform ( in a specific order ) to carry out a specified task, such as calculating employees ' paychecks or printing students ' report cards.

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.

Most algorithms are intended to be implemented as computer programs.

In computer systems, an algorithm is basically an instance of logic written in software by software developers to be effective for the intended " target " computer ( s ), in order for the target machines to produce output from given input ( perhaps null ).

Computers ( and computors ), models of computation: A computer ( or human " computor ") is a restricted type of machine, a " discrete deterministic mechanical device " that blindly follows its instructions.

Simulation of an algorithm: computer ( computor ) language: Knuth advises the reader that " the best way to learn an algorithm is to try it.

The programmer must translate the algorithm into a language that the simulator / computer / computor can effectively execute.

This means that the programmer must know a " language " that is effective relative to the target computing agent ( computer / computor ).

Canonical flowchart symbols: The graphical aide called a flowchart offers a way to describe and document an algorithm ( and a computer program of one ).

Written in prose but much closer to the high-level language of a computer program, the following is the more formal coding of the algorithm in pseudocode or pidgin code:
