A directory is a special file of Linux system organization files. To enable users to better use the catalog, we introduce some basic concepts about the catalog. Working directory and user home directory logically, users are in a directory every moment after they log on to the Linux system, which is called the working directory or the current directory (sharable directory). The working directory can be changed at any time. When a user initially logs on to the system, its home directory becomes its working directory. Working directory with "....

Wikipedia's explanation: cloud Computing (cloud computing, one of the most basic concepts of distributed computing, is to automatically split large computing processes into countless smaller subroutines via the network, and then to a large system of multiple servers that are searched, The processing results are passed back to the user after the analysis is calculated. 　　Through this technology, network service providers can in a few seconds, to deal with tens of millions of millions of information, to achieve the "super computer" and the same powerful network services. The simplest cloud computing ...
