• 10:58, 7 March 2024 Philip talk contribs created page Glossaire:2FA/fr (Created page with "L'authentification à deux étapes ou 2FA (Two Factor Authentication en anglais) est un système de connexion dans lequel vous devez non seulement fournir un mot de passe ("quelque chose que vous savez"), mais aussi prouver que vous possédez un objet ("quelque chose que vous avez") ou fournir un élément biométrique tel qu'une empreinte digitale ("quelque chose que vous êtes"). Cela rend le système beaucoup plus difficile à pirater.")
• 10:07, 28 February 2024 Philip talk contribs created page Glossary:TRF (Created page with "A TRF or Tuned Radio Frequency radio receiver is one in which the signal from the aerial is tuned and amplified at its incoming frequency before demodulation to recover the audio (or other) transmitted material. If the radio is to be tunable, this means that several tuned circuits have to be tuned in step, a problem overcome in the superhet radio design.")
• 08:50, 27 February 2024 Philip talk contribs created page Glossary:WAF (Created page with "The WAF or Wife Acceptance Factor is an estimation of the probability that your partner will accept the installation of your latest techie toy in the living room without an irreversible breakdown in your relationship.")
• 22:27, 25 February 2024 Philip talk contribs created page Glossary:Port (Created page with "A TCP or UDP port is simply a number designating a particuar service on a server. For example connecting to a computer with port number 80, the connection will be routed to the computer's web server software, or if you want an encrypted connection you connect to TCP port 443. Many other services for example email, DNS, time services, file and print services are distinguished by well known port numbers.")
• 15:59, 24 February 2024 Philip talk contribs created page Glossary:X.509 (Created page with "X.509 is a standard defining a format for a digital certificate which creates a strong association between a identity such as a web site and a public key. That public key can then be used to digitally sign a web page coming from the web site. The digital certificate itself is signed by a chain of higher level digital certificates ending in a "root certificate" which everyone trusts.")
• 15:11, 24 February 2024 Philip talk contribs created page Glossary:E-Series (Created page with "The E series (E3, E6, E12, E24 etc) is a system of standard values for resistors, capacitors, inductors and zener diodes dividing each decade equally on a logarithmic scale. So for example, E12 resistors come in 12 values per decade, each roughly 20% greater than the last. See E Series in Wikipedia for more details.")

• 22:43, 23 February 2024 Philip talk contribs created page Glossary:SIM swap (Created page with "A SIM-swap attack is when a criminal convinces your mobile provider to give them a new SIM card for your phone. When they activate it your phone will go dead and they will then be able to request SMS-based password resets for your email and other online accounts, all of which will now go to their phone instead of yours. This is going to be a very bad day for you.")
• 22:27, 23 February 2024 Philip talk contribs created page Glossary:DNS (Created page with "DNS or the Domain Name System is the Internet-wide distributed system for looking up the IP address of a domain, such as restarters.net, required for routing data.

• 21:44, 23 February 2024 Philip talk contribs created page Glossary:Symmetric cryptography (Created page with "In symmetric cryptography, decryption simply runs the encryption process backwards using the same key, unlike asymmetric or public key cryptography. AES is the commonest example. A problem is that for two parties to communicate securely they first need to securely agree a key. Public key cryptography overcomes this, but is computationally much more expensive.")
• 15:17, 22 February 2024 Philip talk contribs created page Glossary:Public key cryptography (Created page with "Public key or asymmetric cryptography is a form of encryption using separate keys for encryption and decryption, neither of which can be derived from the other. The public key can be used to encrypt messages which only the holder of the corresponding private key can decrypt. Alternatively, the holder of a private key can "digitally sign" a message by encrypting a digest of the message with his private key. By successfully decrypting the digest with the previously publish...")
• 14:39, 22 February 2024 Philip talk contribs created page Glossary:TLS (Created page with "TLS or Transport Layer Security is a standard for securing data over a TCP data stream. It offers encryption using a shared key derived using a secure key exchange mechanism, and allows one or both ends to identify themselves using digital certificates. It has superceded SSL, but "SSL" is still often used to describe a link actually secured by TLS.")
• 12:54, 22 February 2024 Philip talk contribs created page Glossary:SSL (Created page with "SSL or Secure Sockets Layer is a deprecated standard for securing data over a TCP data stream. It offers encryption using a shared key derived using a secure key exchange mechanism, and allows one or both ends to identify themselves using digital certificates. SSL went through several major versions, but 3.0 was deprecated in 2015 and has been superseded by TLS. Nevertheless, "SSL" is still often used to describe a link actually secured...")
• 16:38, 20 February 2024 Philip talk contribs created page Glossary:IMAP (Created page with "If you manage your email using a program or app on your own device (rather than using webmail) then IMAP or Internet Message Access Protocol provides a method by which your program or app can manage your email, optionally organised into different folders, held on a remote email server, and to retrieve emails as required.")

• 21:39, 19 February 2024 Philip talk contribs created page Glossary:Entropy (Created page with "Entropy (in information theory) is the amount of information or uncertainty in a piece of data, usually measured in bits. For example a 3 digit PIN or combination lock has 1,000 possible values and so has almost 10 bits of entropy, because 10 bits allows you to count up to 1,024. The entropy of a password or encryption key can be used directly to estimate how long it might take to crack, by trying all possible values.")
• 21:14, 19 February 2024 Philip talk contribs created page Glossary:Signal to Noise Ratio (Created page with "The Signal to Noise (or S/N) ratio is a measure of the strength of a signal compared to any background noise or interference, and is measured in decibels (dB). In an audio system, a high S/N ratio tells you that any background hiss will be imperceptible, and in data communications, the S/N ratio directly affects the rate at which you can transmit data.")
• 21:14, 19 February 2024 Philip talk contribs created page Glossary:Decibel (Created page with "Decibels (dB) are a measure of relative power, for example by what factor does an amplifier increase the power of a signal, or by what factor is a TV signal reduced by losses in the cable between the aerial and the receiver. It's a logarithmic scale, 3dB representing a doubling of power, hence the dB gains or losses in a signal path can simply be added.")
• 17:52, 19 February 2024 Philip talk contribs created page Glossary:Noise (Created page with "Noise, in the context of electronics and communications, is any unwanted interference tending to mask a desired signal. It can never be eliminated entirely as the electronics we're surrounded with all generates a certain amount of interference, and an electric current itself consists of a random flow of electrons.")
• 17:40, 19 February 2024 Philip talk contribs created page Glossary:Metadata (Created page with "Metadata is "data about data". For example, a document or spreadsheet may contain information about the author; a digital camera will normally embed information about the exposure, location, date and time of a photo. Sharing these or other types of file can result in undesirable information leakage and privacy issues if you're not aware of the metadata they may contain.")
• 17:24, 19 February 2024 Philip talk contribs created page Glossary:Decoupling capacitor (Created page with "Variations in the current drawn by one part of a circuit can affect the voltage of the supply, hence affecting another part of the circuit.

• 11:30, 15 February 2024 Philip talk contribs created page MPP inverter (Created page with "Getting the most power out of a PV (or solar) cell or wind turbine isn't straightforward. The output voltage will be maximum if you draw hardly any current, and if you draw as much current as you can the output voltage will drop almost to zero. In either case the power delivered (voltage × current) will be minimal. An MPP or Maximum Power Point controller or inverter will continuously adjust the current drawn in order to maximise the power, for exam...")
