Software Development
Software development is the process of conceiving, specifying, designing, programming, documenting, testing, and bug fixing involved in creating and maintaining applications, frameworks, or other software components. Software development involves writing and maintaining the source code, but in a broader sense, it includes all processes from the conception of the desired software through to the final manifestation of the software, typically in a planned and structured process. Software development also includes research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products. Methodologies One system development methodology is not necessarily suitable for use by all projects. Each of the available methodologies are best suited to specific kinds of projects, based on various technical, organizational, project, and team considerations. Software development activities Identification of need The s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Computer
A computer is a machine that can be programmed to Execution (computing), carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as Computer program, programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the Computer hardware, hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devi ...

Software
Software is a set of computer programs and associated software documentation, documentation and data (computing), data. This is in contrast to Computer hardware, hardware, from which the system is built and which actually performs the work. At the low level language, lowest programming level, executable code consists of Machine code, machine language instructions supported by an individual Microprocessor, processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of Binary number, binary values signifying Instruction set architecture, processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction System call, may also invoke one of many Input/output, input or output operations, for example displaying some text on ...

Kaypro
Kaypro Corporation was an American home and personal computer manufacturer based out of San Diego in the 1980s. The company was founded by Non-Linear Systems (NLS) to compete with the popular Osborne 1 portable microcomputer. Kaypro produced a line of rugged, "luggable" CP/M-based computers sold with an extensive software bundle which supplanted its competitors and quickly became one of the top-selling personal computer lines of the early 1980s. Kaypro was exceptionally loyal to its original customer base but slow to adapt to the changing computer market and the advent of IBM PC compatible technology. It faded from the mainstream before the end of the decade and was eventually forced into bankruptcy in 1992. History Kaypro began as Non-Linear Systems, a maker of electronic test equipment, founded in 1952 by Andrew Kay, the inventor of the digital voltmeter. In the 1970s, NLS was an early adopter of microprocessor technology, which enhanced the flexibility of products such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ladder (video Game)
''Ladder'' is a platform game similar to Nintendo's ''Donkey Kong'' written for the CP/M operating system and made to be operated on the early Kaypro line of luggable computers. ''Ladder'' was written by Yahoo Software of Los Angeles, California. Along with ''Star Trek'', ''CatChum'' and ''Aliens'', ''Ladder'' was one of the games that came with the software bundle of the early Kaypro Kaypro Corporation was an American home and personal computer manufacturer based out of San Diego in the 1980s.

Gameplay Since the Kaypro only has a text mode, the game uses letters, numbers, and symbols lined up to create walls and platforms, pits/traps, characters, trampolines and goals. The floors in ''Ladder'' are made of equal signs, and the ladders themselves are made of capital "H"s stacked on top of each other. The "lad" controlled by the p ...

CatChum
''CatChum'' is a text-only clone of '' Pac-Man'' written for the CP/M operating system and made to be operated on the early Kaypro line of luggable computers. CatChum was made within the limitations of Kaypro's early text-only computers. As a result, the maze is made from a series of dashes and other punctuation marks. The Pac-Man character is a letter C, which goes from upper to lower case intermittently (to simulate a chomping Pac-Man). The four ghosts are capital As (which turn to lowercase ms when the CatChum Pac-Man chomps a power-pellet, capital Ms when the effect is about to end), and the "fruits" are represented by dollar signs. One of the major down sides of this clone is that Kaypros of that era did not have the ability to flip the text characters. As a result, even when the character is chomping pellets on his left, for example, his chomping mouth is still on the right. There is no sound. Instead, flashing text messages appear every now and then saying things like "G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aliens (1982 Video Game)
''Aliens'' is a text-only clone of ''Space Invaders'' written for the CP/M operating system and made to be operated on the early Kaypro line of luggable computers. It was written by Yahoo Software of Los Angeles, California. Along with '' Star Trek'', ''CatChum'', and ''Ladder A ladder is a vertical or inclined set of rungs or steps used for climbing or descending. There are two types: rigid ladders that are self-supporting or that may be leaned against a vertical surface such as a wall, and rollable ladders, such ...'', ''Aliens'' was one of the games that came with the early Kaypro computers. Gameplay Screenshot The game runs in text mode; the aliens are made of letters and punctuation marks. Each level was given a name, displayed on top of the screen, such as "Blood Bath" and "We Come in Peace."

Star Trek (text Game)
''Star Trek'' is a text-based strategy video game based on the ''Star Trek'' television series 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 the source cod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Technology is the application of knowledge to reach practical goals in a specifiable and reproducible way. The word ''technology'' may also mean the product of such an endeavor. The use of technology is widely prevalent in medicine, science, industry, communication, transportation, and daily life. Technologies include physical objects like utensils or machines and intangible tools such as software. Many technological advancements have led to societal changes. The earliest known technology is the stone tool, used in the prehistoric era, followed by fire use, which contributed to the growth of the human brain and the development of language in the Ice Age. The invention of the wheel in the Bronze Age enabled wider travel and the creation of more complex machines. Recent technological developments, including the printing press, the telephone, and the Internet have lowered communication barriers and ushered in the knowledge economy.
