• 14:4514:45, 23 April 2024 diff hist +201‎ N Glossary:Repair ‎ Created page with "Repair is the second option (after reuse) in a circular economy. It has been shown that many devices sent for recycling could actually be repaired relatively easily and hence given a new lease of life." current
• 14:4214:42, 23 April 2024 diff hist +225‎ N Glossary:Reuse ‎ Created page with "Reuse is the preferred option in a circular economy. Many items are discarded because they have been replaced by a newer model, or simply fallen into disuse, but could be given a second life if sold or donated to a new owner." current

• 20:1420:14, 20 April 2024 diff hist +447‎ N Glossary:Gallium ‎ 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." current

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."

A half-duplex channel only allows communication in one direction at a time whereas full duplex allows for simultaneous communication in both directions." current

• 17:0617:06, 20 April 2024 diff hist +390‎ N Glossary:COM port ‎ Created page with "A COM port is a serial interface port using a DB-9 connector, offered by virtally all home and personal computers before the advent of USB. 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."
• 17:0017:00, 20 April 2024 diff hist +438‎ N Glossary:D-subminiature ‎ 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."

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." current
• 16:2416:24, 20 April 2024 diff hist +611‎ N Glossary:RS-232 ‎ 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..."
