Donkey Kong (arcade Game)
is a 1981 platform game developed and published by Nintendo for arcades. As Mario (occasionally referred to as "Jumpman" at the time), the player runs and jumps on platforms and climbs ladders to ascend a construction site and rescue Pauline from a giant gorilla, Donkey Kong. It is the first game in the ''Donkey Kong'' series and Mario's first appearance in a video game. ''Donkey Kong'' was created to salvage unsold arcade cabinets following the failure of Nintendo's '' Radar Scope'' (1980), and was designed for Nintendo of America's audience. Hiroshi Yamauchi, Nintendo's president at the time, assigned the project to first-time video game designer Shigeru Miyamoto. Drawing inspiration from "Beauty and the Beast" and 1930s American media such as ''Popeye'' and '' King Kong'', Miyamoto developed the characters and scenario and designed the game alongside chief engineer Gunpei Yokoi. It was the most complex arcade game at that point, using graphics for characterization, incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hard Disk Drive
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating hard disk drive platter, platters coated with magnetic material. The platters are paired with disk read-and-write head, magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual Block (data storage), blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small disk enclosure, rectangular box. Hard disk drives were introduced by IBM in 1956, and were the dominant secondary storage device for History of general-purpose CPUs, general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TRS-80
The TRS-80 Micro Computer System (TRS-80, later renamed the Model I to distinguish it from successors) is a desktop microcomputer developed by American company Tandy Corporation and sold through their Radio Shack stores. Launched in 1977, it is one of the earliest mass-produced and mass-marketed retail home computers. The name is an abbreviation of ''Tandy Radio Shack, Z80 [microprocessor]'', referring to its Zilog Z80 8-bit microprocessor. The TRS-80 has a full-stroke QWERTY keyboard, 4 kilobyte, KB dynamic random-access memory (DRAM) standard memory, small size and desk area, floating-point Level I BASIC language Interpreter (computing), interpreter in read-only memory (ROM), 64-character-per-line computer monitor, video monitor, and had a starting price of US$600 (equivalent to US$ in ). A cassette tape drive for program storage was included in the original package. While the software environment was stable, the cassette load/save process combined with keyboard bounce issues ...

Commodore PET
The Commodore PET is a line of personal computers produced starting in 1977 by Commodore International. A single all-in-one case combines a MOS Technology 6502 microprocessor, Commodore BASIC in read-only memory, keyboard, monochrome monitor, and, in early models, a cassette deck. Development of the system began in 1976, and it was demonstrated and sold as the first personal computer for the masses at the January 1977 Consumer Electronics Show. The name "PET" was suggested by Andre Souson after he saw the Pet Rock in Los Gatos, and stated they were going to make the "pet computer". It was backronymed to Personal Electronic Transactor. In a 1995 retrospective, ''Byte'' magazine—and subsequently many others—referred to the PET, Apple II and TRS-80 collectively as the "1977 trinity" of pioneering personal computers. Following the initial PET 2001, the design was updated through a series of models with more memory, better keyboard, larger screen, and other modifications. ...

Star Trek (1971 Video Game)
''Star Trek'' is a text-based strategy video game based on the ''Star Trek'' television series (1966–69) and originally released in 1971. In the game, the player commands the USS ''Enterprise'' on a mission to hunt down and destroy an invading fleet of Klingon warships. The player travels through the 64 quadrants of the galaxy to attack enemy ships with phasers and photon torpedoes in turn-based battles and refuel at starbases. The goal is to eliminate all enemies within a random time limit. Mike Mayfield wrote the game in the BASIC programming language for the SDS Sigma 7 mainframe computer with the goal of creating a game like ''Spacewar!'' (1962) that could be played with a teleprinter instead of a graphical display. He then rewrote it for the HP 2000C minicomputer in 1972, and it was included in Hewlett-Packard's public domain software catalog the following year. It was picked up from there by David H. Ahl, who ported it with Mary Cole to BASIC-PLUS and published t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronics
Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other Electric charge, electrically charged particles. It is a subfield of physics and electrical engineering which uses Passivity (engineering), active devices such as transistors, diodes, and integrated circuits to control and amplify the flow of electric current and to convert it from one form to another, such as from alternating current (AC) to direct current (DC) or from analog signal, analog signals to digital signal, digital signals. Electronic devices have significantly influenced the development of many aspects of modern society, such as telecommunications, entertainment, education, health care, industry, and security. The main driving force behind the advancement of electronics is the semiconductor industry, which continually produces ever-more sophisticated electronic devices and circuits in respo ...

Piano Sonata No
A piano is a keyboard instrument that produces sound when its keys are depressed, activating an Action (music), action mechanism where hammers strike String (music), strings. Modern pianos have a row of 88 black and white keys, tuned to a chromatic scale in equal temperament. A musician who specializes in piano is called a pianist. There are two main types of piano: the #Grand, grand piano and the #Upupright piano. The grand piano offers better sound and more precise key control, making it the preferred choice when space and budget allow. The grand piano is also considered a necessity in venues hosting skilled pianists. The upright piano is more commonly used because of its smaller size and lower cost. When a key is depressed, the strings inside are struck by felt-coated wooden hammers. The vibrations are transmitted through a Bridge (instrument), bridge to a Soundboard (music), soundboard that amplifies the sound by Coupling (physics), coupling the Sound, acoustic energy t ...

Orthogonality
In mathematics, orthogonality is the generalization of the geometric notion of '' perpendicularity''. Although many authors use the two terms ''perpendicular'' and ''orthogonal'' interchangeably, the term ''perpendicular'' is more specifically used for lines and planes that intersect to form a right angle, whereas ''orthogonal'' is used in generalizations, such as ''orthogonal vectors'' or ''orthogonal curves''. ''Orthogonality'' is also used with various meanings that are often weakly related or not related at all with the mathematical meanings. Etymology The word comes from the Ancient Greek ('), meaning "upright", and ('), meaning "angle". The Ancient Greek (') and Classical Latin ' originally denoted a rectangle. Later, they came to mean a right triangle. In the 12th century, the post-classical Latin word ''orthogonalis'' came to mean a right angle or something related to a right angle.
