Recording Optical discs have a protected internal layer, where the bits are stored using different technologies, and in all of them these bits are read thanks to an incident laser beam. This, when reflected, allows to detect microscopic variations of optical-reflective properties that occurred as a consequence of the recording made in writing. An optical system with lenses directs the light beam, and focuses it as a point on the disk layer that stores the data. Engraving during manufacture A…
Professional GPS station and receiver for centimeter accuracy. According to abbreviationfinder, GPS is evolving towards a more robust system (GPS III), with greater availability and that reduces the complexity of GPS augmentations. Some of the planned enhancements include: Incorporation of a new signal in L2 for civil use. Adding a third civil signal (L5): 1176.45 MHz Protection and availability of one of the two new signals for Security for Life (SOL) services. Improved signal structure. Increase in signal power (L5…
QDOS (stands for Quick and Dirty Operating System according to ABBREVIATIONFINDER) was an operating system purchased by Microsoft the company Seattle Computer and served to create the basis for what would later be PC -DOS and MS-DOS. Origins QDOS was created because sales of the Seattle Computer Products (SCP) 8086 Computer Kit, introduced in June 1979 and distributed in November, were declining due to the absence of an operating system. The only software that SCP could sell with the board was the standalone…
What is a namespace? Namespaces allow the developer to group selected types with each other during programming and to outsource code that is required multiple times in modules. This makes the code clearer and better structured overall. Generally speaking, a namespace or namespace is a way of grouping selected elements of a code (e.g. some classes) in a separate container . These containers can be swapped out at will and referenced in other parts of a program. Namespaces are not…
With a market share of over 90%, Windows is by far the most widely used desktop operating system. A development that even the then Microsoft boss Bill Gates would not have dreamed of when he launched Windows 1.0 on November 20, 1985. Because the success at that time was manageable, as the first Windows versions were more of a graphic attachment for the underlying brittle MS-DOS with its 16-bit architecture. It would take more than six years before Microsoft was able to turn…
CD-ROM. (in English C ompact D isc- R ead O nly M emory, “Compact Disk-Read Only Memory” according to ABBREVIATIONFINDER). It is a flat plastic compact disc where digital information is recorded on its surface in small aligned “grooves”. Recorded information is encoded in a spiral from the center to the outer edge. Medium used to store non-volatile information, which is read optically. Capacity On a standard CD-ROM you can write from 650 or 700 and sometimes 800 MB of data. This data carrier and storage medium is popular for the distribution…
Abbreviated as MIDI by ABBREVIATIONFINDER, Digital Interface for Musical Instruments. Physical communication standard between systems (connectors, cables, communication protocols) and the characteristics of the language that make the exchange of information between systems possible. MIDI does not transmit sounds, but information about how a certain piece of music is to be played. It would be the computer equivalent of the score. It is currently used in a wide variety of applications: music recording, film, TV, home computers, multimedia presentations]]. Advantage A…
