The Kenbak-1, released in early 1971, is considered by the Computer History Museum to be the world's first personal computer. It was designed and invented by John Blankenbaker of Kenbak Corporation in 1970, and was first sold in early 1971. Unlike a modern personal computer, the Kenbak-1 was built of small-scale integrated circuits, and did not ...
v. t. e. 3D computer graphics, sometimes called CGI, 3-D-CGI or three-dimensional computer graphics, are graphics that use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering digital images, usually 2D images but sometimes 3D images.
Ternary computing is commonly implemented in terms of balanced ternary, which uses the three digits −1, 0, and +1. The negative value of any balanced ternary digit can be obtained by replacing every + with a − and vice versa. It is easy to subtract a number by inverting the + and − digits and then using normal addition.

Raspberry Pi (/ p aɪ /) is a series of small single-board computers (SBCs) developed in the United Kingdom by the Raspberry Pi Foundation in association with Broadcom.Since 2013, Raspberry Pi devices have been developed and supported by a subsidiary of the Raspberry Pi Foundation, now named Raspberry Pi Ltd. The Raspberry Pi project originally leaned toward the promotion of teaching basic ...
A central processing unit ( CPU ), also called a central processor, main processor, or just processor, is the most important processor in a given computer. [1] [2] Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. [3] [4] [5] This role contrasts with ...
An image created by using POV-Ray 3.6. Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. [citation needed] The resulting image is referred to as a rendering. Multiple models can be defined in a scene file containing objects in a strictly ...
Computer program. A computer program is a sequence or set [a] of instructions in a programming language for a computer to execute. It is one component of software, which also includes documentation and other intangible components. [1] A computer program in its human-readable form is called source code.
