Data Acquisition
Data acquisition is the process of sampling signals that measure real-world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the acronyms ''DAS,'' ''DAQ,'' or ''DAU,'' typically convert analog waveforms into digital values for processing. The components of data acquisition systems include: * Sensors, to convert physical parameters to electrical signals. * Signal conditioning circuitry, to convert sensor signals into a form that can be converted to digital values. * Analog-to-digital converters, to convert conditioned sensor signals to digital values. Data acquisition applications are usually controlled by software programs developed using various general purpose programming languages such as Assembly, BASIC, C, C++, C#, Fortran, Java, LabVIEW, Lisp, Pascal, etc. Stand-alone data acquisition systems are often called data loggers. There are also open-source softw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cumulus Corporation
Cumulus Corporation (often shortened to Cumulus Corp.) was an American computer peripheral and system manufacturer active from 1987 to 1993. Based in Beachwood, Ohio (a suburb of Cleveland) and started by Tecmar founder Martin Alpert, the company set out to exclusively manufacture expansion products for IBM's Personal System/2 (PS/2) family of computers—mainly RAM expansion cards. It later released cross-platform CPU upgrade cards and memory expansion cards for other platforms besides the PS/2. Beginning in 1990, the company began trading as Cumulus Computer Corporation and began releasing complete systems of their own. Initially a success story for the tech industry in Cleveland, a botched stock launch in 1992 proved disastrous for the company's ailing cash flow situation, and in 1993 the company was liquidated amid massive debt to suppliers and lenders. Foundation (1987–1988) Cumulus Corporation was founded in Beachwood, Ohio, a suburb of Cleveland, in 1987 by Martin Alp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2007 Disestablishments In Ohio
7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube (algebra), cube. As an early prime number in the series of positive integers, the number seven has greatly symbolic associations in religion, mythology, superstition and philosophy. The seven Classical planets resulted in seven being the number of days in a week. It is often considered lucky in Western culture and is often seen as Symbolism of the Number 7, highly symbolic. Unlike Western culture, in Vietnamese culture, the number seven is sometimes considered unlucky. It is the first natural number whose pronunciation contains more than one syllable. Evolution of the Arabic digit In the Brahmi numerals, beginning, Indians wrote 7 more or less in one stroke as a curve that looks like an uppercase vertically inverted. The western Ghubar Arabs' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit m ...

Travan
Travan is an 8 mm magnetic tape cartridge design developed by the 3M company, used for the storage of data in computer backups and mass storage. Over time, subsequent versions of Travan cartridges and drives have been developed that provide greater data capacity, while retaining the standard 8 mm width and 750' length. Travan is standardized under the QIC body. HP Colorado, Iomega DittoMax and AIWA Bolt are proprietary versions of the Travan format. The Travan format competed mainly against the DDS, AIT, and VXA formats. Generations TR-1 * Travan TR-1 cartridges offer a 400 MB native capacity with a 0.25 MB/s transfer rate using the QIC-80 media format. TR-2 * TR-2 was designed by 3M, but they never marketed it. * TR-2 cartridges were designed to have an 800 MB native capacity with a 0.25 MB/s transfer rate using the QIC-3010 media format. * The spec called for 50 tracks across the tape, with a recording density of 22,125 flux transitions per inch (ftpi).

Quarter Inch Cartridge
Quarter inch cartridge tape (abbreviated QIC, commonly pronounced "quick") is a magnetic tape data storage format introduced by 3M in 1972, with derivatives still in use as of 2016. QIC comes in a rugged enclosed package of aluminum and plastic that holds two tape reels driven by a single belt in direct contact with the tape. The tape was originally wide and anywhere from long. Data is written linearly along the length of the tape in one track (mostly on pre-1980 equipment), or written "serpentine", one track at a time, the drive reversing direction at the end of the tape, and each track's data written in the opposite direction to its neighbor. Since its introduction, it has been widely used, and many variations exist. There is a QIC trade association that publishes QIC standards which include interfaces and logical formats. To a very large extent it was the efficiency and openness of this organization which encouraged hardware and software developers to use this type of drive an ...

Ditto (drive)
The Ditto drive series was a proprietary magnetic tape data storage system released by Iomega during the 1990s. It was marketed as a backup device for personal computers. They were released in several capacities ranging from the original Ditto 250 drive (250MB compressed capacity per cartridge) to the DittoMAX drive, a compatible format with compressed capacities up to 10GB per cartridge. This was accomplished by increasing the physical size of the cartridge (making it longer). Some versions of the drive were also able to read Travan-type tapes. Technical aspects Ditto internal drives were connected through the floppy drive channel and used MFM encoding to store data (the same method as on older floppy drives). An ISA accelerator card called the ''Ditto Dash'', providing higher speed than a stock floppy controller, was also available. Ditto external drives were connected to the parallel port and offered a print-through port which allowed a printer to operate while daisy-cha ...

Iomega
Iomega (later LenovoEMC) produced external, portable, and networked data storage products. Established in the 1980s in Roy, Utah, United States, Iomega sold more than 410 million digital storage drives and disks, including the Zip drive floppy disk system. Formerly a public company, it was acquired by EMC Corporation in 2008, and then by Lenovo, which rebranded the product line as LenovoEMC, until discontinuation in 2018. History Iomega started in Roy, Utah, U.S. in 1980 and moved its headquarters to San Diego, California in 2001. For many years, it was a significant name in the data storage industry. Iomega's most famous product, the Zip Drive, offers relatively large amounts of storage on portable disks. The original Zip disk's 100MB capacity is a huge improvement over the decades-long standard of 1.44MB floppy disks. The Zip Drive became a common internal and external peripheral for IBM-compatible and Macintosh personal computers. However, Zip disks sometimes failed after a ...

Magnetic Tape Data Storage
Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording. Tape was an important medium for primary data storage in early computers, typically using large open reels of IBM 7 track, 7-track, later 9-track tape, 9-track tape. Modern magnetic tape is most commonly packaged in cartridges and cassettes, such as the widely supported Linear Tape-Open (LTO) and IBM 3592 series. The device that performs the writing or reading of data is called a tape drive. Autoloader (data storage device), Autoloaders and tape library, tape libraries are often used to automate cartridge handling and exchange. Compatibility was important to enable transferring data. Tape data storage is now used more for system backup, data archive and data exchange. The low cost of tape has kept it viable for long-term storage and archive. Open reels Initially, magnetic tape for data storage was wound on reels. This standard for large computer systems persis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
