The worm is also known as WannaCrypt, [9] Wana Decrypt0r 2.0, [10] WanaCrypt0r 2.0, [11] and Wanna Decryptor. [12]
Mesh network: each node is connected to an arbitrary number of neighbors in such a way that there is at least one traversal from any node to any other. Fully connected network: each node is connected to every other node in the network. Tree network: nodes are arranged hierarchically. This is the natural topology for a larger Ethernet network ...

Data backup techniques include having an encrypted copy of the data offsite. Methods used for transporting data are: [135] Having the customer write the data to a physical medium, such as magnetic tape, and then transporting the tape elsewhere. [136] Directly transferring the data to another site during the backup, using appropriate links.
The ISS has a large number of external components that do not require pressurisation. The largest of these is the Integrated Truss Structure (ITS), to which the station's main solar arrays and thermal radiators are mounted. [145] The ITS consists of ten separate segments forming a structure 108.5 metres (356 ft) long. [8]
The first stage can involve design verification where the expected output of the module is tested through computer simulation. Further, the modules ability to withstand natural environment conditions such as temperature , rain , hail , snow , corrosion , dust , lightning , horizon and near-shadow effects is tested.
