Broad network access. Capabilities are available from the Internet through web-based tools and over the network and accessed through standard applications, rather than a direct connection to a mechanisms that promote use by heterogeneous server. Data and software packages are stored in thin or thick client platforms (e.g., mobile phones, servers. However, cloud computing structure tablets, laptops, and workstations). allows access to information as long as an 5.
