Tandon Corporation
The Tandon Corporation was an American disk drive and PC manufacturer founded in 1975 (incorporated in 1976 as Tandon Magnetics Corp.) by Sirjang Lal Tandon, a former mechanical engineer. The company originally produced magnetic recording read/write heads for the then-burgeoning floppy-drive market. Due to the labor-intensive nature of the product, production was carried out in low-wage India where production costs were lower. This was the key to the company's competitiveness. In the late 1970s, Tandon developed direct equivalents to Shugart floppy drives, and is credited with the invention of DS/DD (double-sided, double-density) versions which became its primary product in the early 1980s. In 1979, Tandon introduced the TM-100 diskette drive, a 5.25" unit with 40 track support as opposed to the Shugart SA-400's 35 tracks. When Tandy introduced the TRS-80 Model III in 1980, they equipped the computer with TM-100s. The following year, Tandon obtained an even more lucrative con ...

Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange ( listed company), which facilitates the trade of shares, or not ( unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), ...

Its competitors include the data management and storage companies Seagate Technology and Micron Technology. History 1970s Western Digital was founded on April 23, 1970, by Alvin B. Phillips, a Motorola employee, as General Digital Corporation, initially a manufacturer of MOS test equipment. It was originally based in Newport Beach, California, shortly thereafter moving to Santa Ana, California, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Storage Companies
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the 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 industrial and 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 devices like personal computers and mobile devices like smartphones. Computers power the Internet, which links bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GW-BASIC
GW-BASIC is a dialect of the BASIC programming language developed by Microsoft from IBM BASICA. Functionally identical to BASICA, its BASIC interpreter is a fully self-contained executable and does not need the Cassette BASIC ROM found in the original IBM PC. It was bundled with MS-DOS operating systems on IBM PC compatibles by Microsoft. The language is suitable for simple games, business programs and the like. Since it was included with most versions of MS-DOS, it was also a low-cost way for many aspiring programmers to learn the fundamentals of computer programming. Microsoft also sold a BASIC compiler, BASCOM, compatible with GW-BASIC, for programs needing more speed. According to Mark Jones Lorenzo, given the scope of the language, "GW-BASIC is arguably the ''List_of_Latin_phrases_(N)#ne_plus_ultra, ne plus ultra'' of Microsoft's family of line-numbered BASICs stretching back to Altair BASIC and perhaps even of line-numbered BASIC in general." With the release of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MS-DOS
MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax, and capabilities. Beginning in 1988 with DR-DOS, Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stepper Motor
A stepper motor, also known as step motor or stepping motor, is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can be commanded to move and hold at one of these steps without any position sensor for feedback (an open-loop controller), as long as the motor is correctly sized to the application in respect to torque and speed. Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated. Mechanism Brushed DC motors rotate continuously when DC voltage is applied to their terminals. The stepper motor is known for its property of converting a train of input pulses (typically square waves) into a precisely defined increment in the shaft’s rotational position. Each pulse rotates the shaft through a fixed angle. Stepper motors effectively have multiple "toothed" electromagnets arranged as a stator around a central rotor, a gear-shaped piece of iron. Th ...

Chatsworth, California
Chatsworth is a suburban neighborhood in the City of Los Angeles, California, in the San Fernando Valley. The area was home to Native Americans, some of whom left caves containing rock art. Chatsworth was explored and colonized by the Spanish beginning in the 18th century. The land was part of a Spanish land grant, Rancho Ex-Mission San Fernando, in the 19th century, and after the United States took over the land following the Mexican–American War, it was the largest such grant in California. Settlement and development followed. Chatsworth has seven public and eight private schools. There are large open-space and smaller recreational parks as well as a public library and a transportation center. Distinctive features are the former Chatsworth Reservoir and the Santa Susana Field Laboratory. The neighborhood has one of the lowest population densities in Los Angeles and a relatively high income level. Chatsworth is the home of the Iverson Movie Ranch, a 500-acre area whi ...
