https://en.wikipedia.org/wiki/Process%20gain | In a spread-spectrum system, the process gain (or "processing gain") is the ratio of the spread (or RF) bandwidth to the unspread (or baseband) bandwidth. It is usually expressed in decibels (dB).
For example, if a 1 kHz signal is spread to 100 kHz, the process gain expressed as a numerical ratio would be / = 100. Or ... |
https://en.wikipedia.org/wiki/Pulse%20width | The pulse width is a measure of the elapsed time between the leading and trailing edges of a single pulse of energy. The measure is typically used with electrical signals and is widely used in the fields of radar and power supplies. There are two closely related measures. The pulse repetition interval measures the time... |
https://en.wikipedia.org/wiki/Passivation%20%28chemistry%29 | In physical chemistry and engineering, passivation is coating a material so that it becomes "passive", that is, less readily affected or corroded by the environment. Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material,... |
https://en.wikipedia.org/wiki/Holborn%209100 | The Holborn 9100 was a personal computer introduced in 1981 by a small Dutch company called Holborn, designed by H.A. Polak. Very few of these devices were sold with Holborn going into bankruptcy on the 27 April 1983.
The 9100 base module is a server, and 9120 is a terminal.

https://en.wikipedia.org/wiki/Datakit | Datakit is a virtual circuit switch which was developed by Sandy Fraser at Bell Labs for both local-area and wide-area networks, and in widespread deployment by the Regional Bell Operating Companies (RBOCs).
Datakit uses a cell relay protocol similar to Asynchronous Transfer Mode. Datakit is a connection-oriented swit... |
https://en.wikipedia.org/wiki/Upload | Uploading refers to transmitting data from one computer system to another through means of a network. Common methods of uploading include: uploading via web browsers, FTP clients], and terminals (SCP/SFTP). Uploading can be used in the context of (potentially many) clients that send files to a central server. While upl... |
https://en.wikipedia.org/wiki/Seven%20Solutions | Seven Solutions is a Spanish hardware technology company headquartered in Granada, Spain, that developed the first white rabbit element on The White Rabbit Project which it was the White Rabbit Switch to use the Precision Time Protocol (PTP) in real application as networking. Seven Solutions got involved on it with t... |
https://en.wikipedia.org/wiki/Inductive%20coupling | In electrical engineering, two conductors are said to be inductively coupled or magnetically coupled when they are configured in a way such that change in current through one wire induces a voltage across the ends of the other wire through electromagnetic induction. A changing current through the first wire creates a... |
https://en.wikipedia.org/wiki/Gravitational%20contact%20terms | In quantum field theory, a contact term is a radiatively induced point-like interaction.
These typically occur when the vertex for the emission of a massless particle such as a photon, a graviton, or a gluon, is proportional to (the invariant momentum of the radiated particle).
This factor cancels the of the Feynm... |
https://en.wikipedia.org/wiki/Ethernet%20over%20USB | Ethernet over USB is the use of a USB link as a part of an Ethernet network, resulting in an Ethernet connection over USB (instead of e.g. PCI or PCIe).
USB over Ethernet (also called USB over Network or USB over IP) is a system to share USB-based devices over Ethernet, Wi-Fi, or the Internet, allowing access to devic... |
