- 08:5508:55, 12 September 2022 diff hist +437 N Glossary:DVI Created page with "DVI is a standard for carrying analogue and/or digital video from a source (most commonly a computer) to a display device. It uses a connector which is almost rectangular, but with two corners on the same long edge slightly rounded. The connectors can accommodate 3 rows of 8 pins plus an extra 4 in a separate group for analogue video, but the number actually present varies according to the type and number of video channels supported."

It uses a connector in standard, mini and micro sizes, all shaped as a rectangle with two chamfered corners on the same long edge." current

It uses a 15 pin D-shaped connector carrying separate analogue signals representing the red, green and blue picture components." current

They can then become reluctant to deliver more charge in future. The cure is to fully dischage then fully recharge them periodically. NiCd batteries are particularly prone, and NiMH rather less so." current Tag: Visual edit

- 16:4316:43, 9 September 2022 diff hist +563 N Glossary:Fibre Optics Created page with "If you feed light into the end of a thin glass or transparent plastic fibre, it will be constrained to the fibre by total internal reflection and emerge at the far end, even if the fibre is many miles long. Furthermore, with high quality fibre the losses can be much less than with an electrical cable, and light can carry vastly more data than an electrical signal. Fibre optics is the application of this principle, together with the ancilliary lasers or Glossary:LED|LED..." Tag: Visual edit
- 16:2716:27, 9 September 2022 diff hist +537 N Glossary:Waveguide Created page with "At the highest frequencies (GHz and above), every bit of wire acts like an aerial, so you can no longer rely on sending a signal down a wire and expecting it to get to the other end. So why not let it do its thing? Feed it into an aerial at the end of a copper pipe and it'll bounce all the way down the inside and come out at the far end. This is what a waveguide is. A microwave oven contains a waveguide to feed the energy from the..." current Tag: Visual edit

One of the predictions of Quantum Mechanics is that sub-atomic particles can effectively be in more than one state at a time. In theory, you should be able to use this property to build a computer that explores many possible solutions to a problem simultaneously rather than trying them one by one, as a normal computer would. This could be really neat for cracking cryptographic codes, or w..." Tag: Visual edit

It has passed every test physiscists have thrown at it, yet nobody understands it, only how to use its predictions to design lasers and silicon chips and al the modern gadgets that depend on them."
