N    20:14  Glossary:Gallium diffhist +447 Philip talk contribs (Created page with "Gallium is a soft metal similar to aluminium but with a low melting point. In electronics, many compounds of gallium are semiconductors with useful properties. Gallium arsenide devices are able to operate at much higher frequencies than their silicon counterparts and so are widely used in mobile phones and satellite comunications. Various other gallium compounds are used in practically all visible and infra-red LEDs.")
N    19:48  Glossary:Silicon Carbide diffhist +440 Philip talk contribs (Created page with "Silicon carbide (as carborundum) has long been used as an abrasive, but it is also a semiconductor with useful properties for high power applications. In recent years silicon carbide devices such as MOSFETs having higher voltage and power ratings than equivalent silicon devices have been increasingly used in applications such as EVs and power conversion.")

Modern computers often still offer simulated COM ports over USB connections for interfacing to simple devices requiring only to be able to exchange a stream of bytes.")

16:24 (cur | prev) +611 Philip talk contribs (Created page with "RS-232 is an old standard originally conceived for communication between a modem and a computer or computer terminal, normally using DB-9 or DB-25 connectors. It was embodied in the COM ports that were once a feature of virtually all personal and home computers. Although now superseded by USB, due to its great simplicity and former ubiquity it is still used where low speed communication is r...")
N    17:15  Glossary:Duplex diffhist +237 Philip talk contribs (Created page with "A duplex comunication channel is one that supports communication in both directions. A half-duplex channel only allows communication in one direction at a time whereas full duplex allows for simultaneous communication in both directions.")

N    17:00  Glossary:D-sub diffhist +438 Philip talk contribs (Created page with "D-subminiature connectors are a series of electrical connectors characterised by their D-shaped shell. Whilst there are numerous variants, just a few are or have been in common use. DB-9 (more correctly DE-9) and DB-25 were ubiqitus on home and personal computers as the serial (COM) and paralel ports before being displaced by USB, and DE-15 is still used for VGA video connectors.")
N    16:35  Glossary:DTE, DCE diffhist +393 Philip talk contribs (Created page with "DTE or Data Terminal Equipment and DCE or Data Communications Equipment are the names given to the two ends of an RS-232 data connection. These were originally assumed to be a computer or computer terminal and a modem respectively but the DCE is now more commonly a computer and the DTE a device or computer controlling it through a command line interface.")
