The Information Framework (formally Shared Information/Data Model or SID) is a unified reference data model providing a single set of terms for business objects in telecommunications. The objective is to enable people in different departments, companies or geographical locations to use the same terms to describe the same real world objects ...
AX.25 is commonly used as the data link layer for network layer such as IPv4, with TCP used on top of that. AX.25 supports a limited form of source routing . Although it is possible to build AX.25 switches similar to the way Ethernet switches work, this has not yet been accomplished.
The first signal report format code may have been QJS. [citation needed]The U.S. Navy used R and K signals starting in 1929. [citation needed]The QSK code was one of the twelve Q Codes listed in the 1912 International Radiotelegraph Convention Regulations, but may have been in use earlier.
Cơm tấm (Vietnamese: [kəːm tə̌m]) is a Vietnamese dish made from rice with fractured rice grains. Tấm refers to the broken rice grains, while cơm refers to cooked rice.
An antenna's impedance is different at different frequencies. An antenna tuner matches a radio with a fixed impedance (typically 50 Ohms for modern transceivers) to the combination of the feedline and the antenna; useful when the impedance seen at the input end of the feedline is unknown, complex, or otherwise different from the transceiver.
KISS (Keep It Simple, Stupid [1]) is a protocol for communicating with a serial terminal node controller (TNC) device used for amateur radio.This allows the TNC to combine more features into a single device and standardizes communications.
For holographic data storage, holographic associative memory (HAM) is an information storage and retrieval system based on the principles of holography. Holograms are made by using two beams of light, called a "reference beam" and an "object beam". They produce a pattern on the film that contains them both. Afterwards, by reproducing the ...
At the end of 2012, seaport.caida.org was the network telescope data capture server with thor.caida.org used for near real-time data access. [ 25 ] [ 37 ] [ 38 ] As of 2016 [update] , the 44/8 network was receiving backscatter from Denial-of-Service attacks (DoS) each measuring ~226 packets per second ( mean peak average) [ 39 ] totalling 37 ...
