A dynamo is an electrical generator that creates direct current using a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor , the alternating-current alternator , and the rotary ...
The dynamo theory describes the process through which a rotating, convecting, and electrically conducting fluid can maintain a magnetic field over astronomical time scales. A dynamo is thought to be the source of the Earth's magnetic field and the magnetic fields of Mercury and the Jovian planets.
Dynamo is a set of techniques that together can form a highly available key-value structured storage system [1] or a distributed data store. [1] It has properties of both databases and distributed hash tables (DHTs). It was created to help address some scalability issues that Amazon experienced during the holiday season of 2004. [2]
Steven Frayne (born 17 December 1982), better known by his former stage name Dynamo [2] [a], is a British magician [3] born in Bradford, West Yorkshire. [ 4 ] His television show Dynamo: Magician Impossible ran from July 2011 to September 2014, and saw him win the Best Entertainment Programme award at the 2012 and 2013 Broadcast Awards.
DYNAMO (DYNAmic MOdels) is a simulation language and accompanying graphical notation developed within the system dynamics analytical framework. It was originally for industrial dynamics but was soon extended to other applications, including population and resource studies [ 1 ] [ 2 ] and urban planning.
Amazon engineers originally avoided Dynamo due to engineering overheads like provisioning and managing partitions and nodes. [6] In response, the DynamoDB team built a service it calls AutoAdmin to manage a database. [30] AutoAdmin replaces a node when it stops responding by copying data from another node.

A Gramme machine, Gramme ring, Gramme magneto, or Gramme dynamo is an electrical generator that produces direct current, named for its Belgian inventor, Zénobe Gramme, and was built as either a dynamo or a magneto. [1] It was the first generator to produce power on a commercial scale for industry.
