Cylinder-head-sector
Cylinder-head-sector (CHS) is an early method for giving addresses to each physical block of data on a hard disk drive. It is a 3D-coordinate system made out of a vertical coordinate ''head'', a horizontal (or radial) coordinate ''cylinder'', and an angular coordinate ''sector''. Head selects a circular surface: a platter in the disk (and one of its two sides). Cylinder is a cylindrical intersection through the stack of platters in a disk, centered around the disk's spindle. Combined, cylinder and head intersect to a circular line, or more precisely: a circular strip of physical data blocks called ''track''. Sector finally selects which data block in this track is to be addressed, as the track is subdivided into several equally-sized portions, each of which is an arc of (360/n) degrees, where n is the number of sectors in the track. CHS addresses were exposed, instead of simple linear addresses (going from ''0'' to the ''total block count on disk - 1''), because early hard drive ...

Disk Sector
In computer disk storage, a sector is a subdivision of a track on a magnetic disk or optical disc. Each sector stores a fixed amount of user-accessible data, traditionally 512 bytes for hard disk drives (HDDs) and 2048 bytes for CD-ROMs and DVD-ROMs. Newer HDDs use 4096-byte (4 KiB) sectors, which are known as the Advanced Format (AF). The sector is the minimum storage unit of a hard drive. Most disk partitioning schemes are designed to have files occupy an integral number of sectors regardless of the file's actual size. Files that do not fill a whole sector will have the remainder of their last sector filled with zeroes. In practice, operating systems typically operate on blocks of data, which may span multiple sectors. Geometrically, the word sector means a portion of a disk between a center, two radii and a corresponding arc (see Figure 1, item B), which is shaped like a slice of a pie. Thus, the ''disk sector'' (Figure 1, item C) refers to the intersection o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economic Sector
One classical breakdown of economic activity distinguishes three sectors: * Primary: involves the retrieval and production of raw-material commodities, such as corn, coal, wood or iron. Miners, farmers and fishermen are all workers in the primary sector. * Secondary: involves the transformation of raw or intermediate materials into goods, as in steel into cars, or textiles into clothing. Builders and dressmakers work in the secondary sector. * Tertiary: involves the supplying of services to consumers and businesses, such as babysitting, cinemas or banking. Shopkeepers and accountants work in the tertiary sector. In the 20th century, economists began to suggest that traditional tertiary services could be further distinguished from " quaternary" and quinary service sectors. Economic activity in the hypothetical quaternary sector comprises information- and knowledge-based services, while quinary services include industries related to human services and hospitality.

Business Sector
In economics, the business sector or corporate sector - sometimes popularly called simply "business" - is "the part of the economy made up by companies". It is a subset of the domestic economy, excluding the economic activities of general government, of private households, and of non-profit organizations serving individuals. The business sector is part of the private sector, but it differs in that the private sector includes all non-government activity, including non-profit organizations, while the business sector only includes business that operate for profit. In the United States the business sector accounted for about 78 percent of the value of gross domestic product (GDP) . Kuwait and Tuvalu each had business sectors accounting for less than 40% of GDP . In systems of state capitalism, much of the business sector forms part of the public sector. In mixed economies, state-owned enterprises may straddle any divide between public and business sectors, allowing analysts ...

Circular Sector
A circular sector, also known as circle sector or disk sector (symbol: ⌔), is the portion of a disk (a closed region bounded by a circle) enclosed by two radii and an arc, where the smaller area is known as the ''minor sector'' and the larger being the ''major sector''. In the diagram, is the central angle, r the radius of the circle, and L is the arc length of the minor sector. The angle formed by connecting the endpoints of the arc to any point on the circumference that is not in the sector is equal to half the central angle. Types A sector with the central angle of 180° is called a '' half-disk'' and is bounded by a diameter and a semicircle. Sectors with other central angles are sometimes given special names, such as quadrants (90°), sextants (60°), and octants (45°), which come from the sector being one 4th, 6th or 8th part of a full circle, respectively. Confusingly, the arc of a quadrant (a circular arc) can also be termed a quadrant. Compass Traditionally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sector (instrument)
The sector, also known as a proportional compass or military compass, was a major calculating instrument in use from the end of the sixteenth century until the nineteenth century. It is an instrument consisting of two rulers of equal length joined by a hinge. A number of scales are inscribed upon the instrument which facilitate various mathematical calculations. It was used for solving problems in proportion, multiplication and division, geometry, and trigonometry, and for computing various mathematical functions, such as square roots and cube roots. Its several scales permitted easy and direct solutions of problems in gunnery, surveying and navigation. The sector derives its name from the fourth proposition of the sixth book of Euclid, where it is demonstrated that similar triangles have their like sides proportional. Some sectors also incorporated a quadrant, and sometimes a clamp at the end of one leg which allowed the device to be used as a gunner's quadrant. History ...

List Of Star Trek Regions Of Space
Several films and episodes of the science fiction franchise ''Star Trek'' are set in distinct astrographical regions of space. Some of these fictional locations exhibit anomalous physical properties; others are defined as sensitive buffer zones under various fictional political accords. This list describes some of the more significant settings for ''Star Trek'' films or story arcs over multiple television episodes. Badlands The Badlands comprise an area of space that appears (or is referenced) in episodes of ''Star Trek: Deep Space Nine'' and '' Star Trek: Voyager''. Located in ''Star Trek''s Alpha Quadrant, the Badlands are characterized by constant plasma storms and funnel clouds. The Maquis use it in several episodes as a meeting or hiding place because of its treacherous navigation. It is also known to harbor some planets hidden within the clouds and nebulae. In " Caretaker", the pilot episode of ''Star Trek: Voyager'', the titular starship pursues a Maquis ship into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foundation Series
The ''Foundation'' series is a science fiction book series written by American author Isaac Asimov. First published as a series of short stories in 1942–50, and subsequently in three collections in 1951–53, for thirty years the series was a trilogy: '' Foundation''; '' Foundation and Empire''; and '' Second Foundation''. It won the one-time Hugo Award for "Best All-Time Series" in 1966. Asimov began adding new volumes in 1981, with two sequels: '' Foundation's Edge'' and '' Foundation and Earth'', and two prequels: ''Prelude to Foundation'' and '' Forward the Foundation''. The premise of the stories is that, in the waning days of a future Galactic Empire, the mathematician Hari Seldon spends his life developing a theory of psychohistory, a new and effective mathematics of sociology. Using statistical laws of mass action, it can predict the future of large populations. Seldon foresees the imminent fall of the Empire, which encompasses the entire Milky Way, and a Dark ...
