Computer data is information processed or stored by a computer. This information may be in the form of text documents, images, audio clips, software programs, or other types of data. Computer data may be processed by the computer's CPU and is stored in files and folders on the computer's hard disk.
Metadata summarizes basic information about data, which can make finding and working with particular instances of data easier. For example, author, date created and date modified and file size are examples of very basic document metadata.
Mobile data is a service provided by a digital mobile network using a packet switched communication path between a mobile device and a data network like the Internet. Other services offered by the same mobile network include voice and short message service (SMS).
