D-subminiature
The D-subminiature or D-sub is a common type of electrical connector. They are named for their characteristic D-shaped metal shield. When they were introduced, D-subs were among the smallest connectors used on computer systems. Description, nomenclature, and variants A D-sub contains two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield, or shell, that provides mechanical support, ensures correct orientation, and may screen against electromagnetic interference. Calling that shield a shell (or D-shell) can be ambiguous, as the term shell is also short for the cable shell, or backshell. D-sub connectors have gender: parts with pin contacts are called ''male connectors'' or ''plugs'', while those with socket contacts are called ''female connectors'' or ''sockets''. The socket's shield fits tightly inside the plug's shield. Panel-mounted connectors usually have #4-40 UNC (as designated with the Unified Thread Standard) jackscrews that ...

RS-232
In telecommunications, RS-232 or Recommended Standard 232 is a standard introduced in 1960 for serial communication transmission of data. It formally defines signals connecting between a ''DTE'' (''data terminal equipment'') such as a computer terminal or PC, and a ''DCE'' ('' data circuit-terminating equipment'' or '' data communication equipment''), such as a modem. The standard defines the electrical characteristics and timing of signals, the meaning of signals, and the physical size and pinout of connectors. The current version of the standard is ''TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange'', issued in 1997. The RS-232 standard had been commonly used with serial ports and serial cables. It is still widely used in industrial communication devices. A serial port complying with the RS-232 standard was once a standard feature of many types of computers. Personal computers used them ...

Parallel Port
In computing, a parallel port is a type of interface found on early computers ( personal and otherwise) for connecting peripherals. The name refers to the way the data is sent; parallel ports send multiple bits of data at once (parallel communication), as opposed to serial communication, in which bits are sent one at a time. To do this, parallel ports require multiple data lines in their cables and port connectors and tend to be larger than contemporary serial ports, which only require one data line. There are many types of parallel ports, but the term has become most closely associated with the printer port or Centronics port found on most personal computers from the 1970s through the 2000s. It was an industry ''de facto'' standard for many years, and was finally standardized as IEEE 1284 in the late 1990s, which defined the Enhanced Parallel Port (EPP) and Extended Capability Port (ECP) bi-directional versions. Today, the parallel port interface is virtually non ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serial Port
A serial port is a serial communication Interface (computing), interface through which information transfers in or out sequentially one bit at a time. This is in contrast to a parallel port, which communicates multiple bits simultaneously in Parallel communication, parallel. Throughout most of the history of personal computers, data has been transferred through serial ports to devices such as modems, computer terminal, terminals, various peripherals, and directly between computers. While interfaces such as Ethernet, FireWire, and USB also send data as a serial Stream (computing), stream, the term ''serial port'' usually denotes Computer hardware, hardware compliant with RS-232 or a related standard, such as RS-485 or RS-422. Modern consumer personal computers (PCs) have largely replaced serial ports with higher-speed standards, primarily USB. However, serial ports are still frequently used in applications demanding simple, low-speed interfaces, such as industrial automation sys ...

Atari ST
Atari ST is a line of personal computers from Atari Corporation and the successor to the company's Atari 8-bit computers, 8-bit computers. The initial model, the Atari 520ST, had limited release in April–June 1985, and was widely available in July. It was the first personal computer with a bitmapped color graphical user interface, using a version of Digital Research's GEM (desktop environment), GEM environment from February 1985. The Atari 1040ST, released in 1986 with Megabyte, 1 MB of memory, was the first home computer with a cost per kilobyte of RAM under US$1/KB. After Jack Tramiel purchased the assets of the Atari, Inc. consumer division in 1984 to create Atari Corporation, the 520ST was designed in five months by a small team led by Shiraz Shivji. Alongside the Mac (computer), Macintosh, Amiga, Apple IIGS and Acorn Archimedes, the ST is part of a mid-1980s generation of computers with 16 or 16/32-bit processors, 256 kilobyte, KB or more of RAM, and computer m ...

Gender Of Connectors And Fasteners
In electrical and machine, mechanical trades and manufacturing, each half of a pair of mating Electrical connector, connectors or fasteners is conventionally designated as male or female, a distinction referred to as its gender. The female connector is generally a receptacle that receives and holds the male connector. Gender of connectors and fasteners#Abbreviations and alternate terminology, Alternative terms such as ''plug'' and ''socket'' or ''jack'' are sometimes used, particularly for Electrical connector#Jacks and plugs, electrical connectors. The assignment is a direct analogy with male and female Sex organ, genitalia. The part bearing one or more protrusions, or which fits inside the other, is designated ''male'', while the one with the corresponding indentations, or fitting outside the other, is designated ''female''. Extension of the analogy results in the verb ''to mating, mate'' being used to describe the process of connecting two corresponding parts together. In som ...

VGA Connector
The Video Graphics Array (VGA) connector is a standard connector used for computer video output. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, as well as many monitors, projectors and HD television sets. Other connectors have been used to carry VGA-compatible signals, such as mini-VGA or BNC, but "''VGA connector''" typically refers to this design. Devices continue to be manufactured with VGA connectors, although newer digital interfaces such as DVI, HDMI and DisplayPort are increasingly displacing VGA, and many modern computers and other devices do not include it. Physical design The VGA connector is a three-row, 15-pin D-subminiature connector referred to variously as DE-15, HD-15 or commonly DB-15(HD). DE-15 is the accurate nomenclature under the proprietary D-sub specifications: an "E" size D-sub connector, with 15 pins in three rows. Predecessor and early variant The standard 15-pin VGA ...

Cannon (company)
ITT Interconnect Solutions, a division of ITT Inc., is a globally diversified connector and connector assembly manufacturing company, headquartered in Irvine, California. Founded in 1915 as Cannon by James H. Cannon, the company developed some of the first equipment for sound films in the early years of the movie industry, including a synchronous motor drive to remotely operate a motion picture projector together with a phonograph. The first "Cannon plug", the M-1 connector, was initially designed as a quick grounding connection for the electrical motor on a portable meat grinder and was adapted for movie sound equipment, enabling the new electrical camera to move freely about while “shooting” a scene. Cannon's M-1 connector was incorporated into the sound equipment used to make the first "talking" motion picture, ''The Jazz Singer''. Cannon continued to develop connectors for the entertainment industry, including the “P” Series audio connectors developed for Paramount Stu ...

Jackscrew
A jackscrew, or screw jack, is a type of jack that is operated by turning a leadscrew. It is commonly used to lift moderate and heavy weights, such as vehicles; to raise and lower the horizontal stabilizers of aircraft; and as adjustable supports for heavy loads, such as the foundations of houses. Description A screw jack consists of a heavy-duty vertical screw with a load table mounted on its top, which screws into a threaded hole in a stationary support frame with a wide base resting on the ground. A rotating collar on the head of the screw has holes into which the handle, a metal bar, fits. When the handle is turned clockwise, the screw moves further out of the base, lifting the load resting on the load table. In order to support large load forces, the screw is usually formed with Acme threads. Advantages An advantage of jackscrews over some other types of jack is that they are ''self-locking'', which means when the rotational force on the screw is removed, it will remain ...

Computer Case Screws
Computer case screws are the hardware used to secure parts of a Personal computer, PC to the computer case, case. Although there are numerous manufacturers of computer cases, they have generally used three thread sizes. The Unified Thread Standard (UTS) originates from the United States, while the ISO metric screw thread is standardized worldwide. In turn, these Screw#Thread standards, thread standards define preferred size combinations that are based on generic units—some on the inch and others on the millimetre. The #6-32 UNC screws are often found on 3.5" hard disk drives and the case's body to secure the covers. The M3 threaded holes are often found on 5.25" optical disc drives, 3.5" floppy drives, and 2.5" drives. Motherboards and other circuit boards often use a #6-32 UNC standoff. #4-40 UNC thumb screws are often found on the ends of Digital Visual Interface, DVI, VGA connector, VGA, Serial port, serial and Parallel port, parallel connectors.
