Random-access Memory
Random-access memory (RAM; ) is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks, CD-RWs, DVD-RWs and the older magnetic tapes and drum memory), where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement. RAM contains multiplexing and demultiplexing circuitry, to connect the data lines to the addressed storage for reading or writing the entry. Usually more than one bit of storage is accessed by the same address, and RAM devices often have multiple data lines and are said to be "8-bit" or "16-bit", etc. ...

South Bend Tribune
The ''South Bend Tribune'' is a daily newspaper and news website which is based in South Bend, Indiana. It is distributed in South Bend, Mishawaka, north central Indiana, and southwestern Michigan. It has been named as a "Blue Ribbon Newspaper" (2006, 2016 and 2018) by the Hoosier State Press Association. It is the third largest daily broadsheet newspaper in the state of Indiana by circulation. The Tribune was locally and family owned by Schurz Communications and based in Mishawaka, for more than 146 years, from its founding in 1872 until 2019. Five generations of the family owned and operated the newspaper until The Tribune was sold to GateHouse Media on Feb. 1, 2019. In November 2019, GateHouse Media completed the purchase of the Gannett newspaper chain; the two combined newspaper chains use the Gannett name. On Nov. 19, 2019, the South Bend Tribune became a Gannett newspaper. Also in November 2019, the South Bend Tribune moved out of the Tribune Building at 225 W. Colfax ...

Courier Journal
The ''Courier Journal'', also known as the ''Louisville Courier Journal'' (and informally ''The C-J'' or ''The Courier''), and called ''The Courier-Journal'' between November 8, 1868, and October 29, 2017, is the highest circulation newspaper in Kentucky. It is owned by Gannett and billed as "Part of the ''USA Today'' Network". According to the ''1999 Editor & Publisher International Yearbook'', the paper is the 48th-largest daily paper in the United States. History Origins ''The Courier-Journal'' was created from the merger of several newspapers introduced in Kentucky in the 19th century. A pioneer paper called ''The Focus of Politics, Commerce and Literature'' was founded in 1826 in Louisville when the city was an early settlement of less than 7,000 individuals. In 1830 a new newspaper, ''The Louisville Daily Journal'', began distribution in the city and, in 1832, the ''Journal'' absorbed ''The Focus of Politics, Commerce and Literature''. The Louisville ''Journal'' was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead–acid Battery
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, their ability to supply high surge currents means that the cells have a relatively large power-to-weight ratio. These features, along with their low cost, make them attractive for use in motor vehicles to provide the high current required by starter motors. Lead-acid batteries suffer from relatively short cycle lifespan (usually less than 500 deep cycles) and overall lifespan (due to the "double sulfation" in the discharged state). As they are inexpensive compared to newer technologies, lead–acid batteries are widely used even when surge current is not important and other designs could provide higher energy densities. In 1999, lead–acid battery sales accounted for 40–50% of the value fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acoustic Coupler
In telecommunications, an acoustic coupler is an interface device for coupling electrical signals by acoustical means—usually into and out of a telephone. The link is achieved through converting electric signals from the phone line to sound and reconvert sound to electric signals needed for the end terminal, such as a teletypewriter, and back, rather than through direct electrical connection. History and applications Prior to its breakup in 1984, Bell System's legal monopoly over telephony in the United States allowed the company to impose strict rules on how consumers could access their network. Customers were prohibited from connecting equipment not made or sold by Bell to the network. The same set-up was operative in nearly all countries, where the telephone companies were nationally owned. In many households, telephones were hard-wired to wall terminals before connectors like RJ11 and BS 6312 became standardized. The situation was similar in other countries. In Austral ...

Mainframe Computer
A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing. A mainframe computer is large but not as large as a supercomputer and has more processing power than some other classes of computers, such as minicomputers, servers, workstations, and personal computers. Most large-scale computer-system architectures were established in the 1960s, but they continue to evolve. Mainframe computers are often used as servers. The term ''mainframe'' was derived from the large cabinet, called a ''main frame'', that housed the central processing unit and main memory of early computers. Later, the term ''mainframe'' was used to distinguish high-end commercial computers from less powerful machines. Design Modern mainframe design is characterized less by ...

Insert Key
The Insert key (often abbreviated Ins) is a key commonly found on computer keyboards. It is primarily used to switch between the two text-entering modes on a personal computer (PC) or word processor: * overtype mode, in which the cursor, when typing, overwrites any text that is present in the current location; and * insert mode, where the cursor inserts a character at its current position, forcing all characters past it one position further. The insert/overtype mode toggling is not global for the computer or even for a single application but rather local to the text input window in which the Insert key was pressed. Overview On early text-based computing environments and terminals, when the cursor is in overtype mode, it was represented as a block that surrounded the entire letter to be overstruck; when in insert mode, the cursor consisted of the vertical bar that is highly common among modern applications, or a blinking underline under the position where a new character w ...

Cassette Tape
The Compact Cassette or Musicassette (MC), also commonly called the tape cassette, cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. Invented by Lou Ottens and his team at the Dutch company Philips in 1963, Compact Cassettes come in two forms, either already containing content as a prerecorded cassette (''Musicassette''), or as a fully recordable "blank" cassette. Both forms have two sides and are reversible by the user. Although other tape cassette formats have also existed - for example the Microcassette - the generic term ''cassette tape'' is normally always used to refer to the Compact Cassette because of its ubiquity. Its uses have ranged from portable audio to home recording to data storage for early microcomputers; the Compact Cassette technology was originally designed for dictation machines, but improvements in fidelity led to it supplanting the stereo 8-track cartridge ...

Selectric
The IBM Selectric typewriter was a highly successful line of electric typewriters introduced by IBM on 31 July 1961. Instead of the "basket" of individual typebars that swung up to strike the ribbon and page in a typical typewriter of the period, the Selectric had an "element" (frequently called a "typeball", or less formally, a "golf ball") that rotated and pivoted to the correct position before striking the paper. The element could be easily interchanged to use different fonts within the same document typed on the same typewriter, resurrecting a capability which had been pioneered by typewriters such as the Hammond and Blickensderfer in the late 19th century. The Selectric also replaced the traditional typewriter's horizontally-moving carriage with a roller ( platen) that turned to advance the paper vertically, while the typeball and ribbon mechanism moved horizontally across the paper. The Selectric mechanism was notable for using internal mechanical binary coding and two m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cathode-ray Tube
A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a Phosphorescence, phosphorescent screen. The images may represent electrical waveforms (oscilloscope), pictures (television set, computer monitor), radar targets, or other phenomena. A CRT on a television set is commonly called a picture tube. CRTs have also been Williams tube, used as memory devices, in which case the screen is not intended to be visible to an observer. The term ''cathode ray'' was used to describe electron beams when they were first discovered, before it was understood that what was emitted from the cathode was a beam of electrons. In CRT television sets and computer monitors, the entire front area of the tube is scanned repeatedly and systematically in a fixed pattern called a raster scan, raster. In color devices, an image is produced by controlling the intensity of each of three electron beams, one for each ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
