Electronvolt is equal to . It is a common unit of energy within physics, widely used in solid state, atomic, nuclear, and particle physics. It is commonly used with the metric prefixes milli-, kilo-, mega-, giga-, tera-, peta- or exa- (meV, keV, MeV, GeV, TeV, PeV and EeV respectively). In some older documents, and in the name Bevatron, the symbol BeV is used, which stands for billion (10) electronvolts; it is equivalent to the GeV. An electronvolt is the amount of energy gained (or lost) by the charge of a single electron moving across an electric potential difference of one volt.
Zetta (cloud backup) disaster recovery testing. The software supports Windows, Linux, and Mac and has plug-ins for SQL, MS Exchange, Hyper-V, VMware, and NetApp filers. Zetta has been awarded several patents for its backup and disaster recovery technology, including for minimizing network bandwidth for replication/backup, ensuring that the data that is replicated is the same, bit for bit, as on the source system and is able to scale to Internet volumes of data. Zetta's agent eliminates network round trips by having a client side cache of the server state, extensive parallelism and WAN optimization. Zetta also provides a mountable backup. Zetta was founded
