Data transfer, also commonly referred to as digital transmission and data transmission, refers to the physical transferal of data over a communications channel. In the context of hosting, this transfer takes place largely over fiber optic lines, copper wires and wireless infrastructure.
The data transmitted across a network can originate from a variety of sources, from analog videos and telephone calls to digital messages sent between computers and mobile devices. Digital transmission to end-user customers has been possible since the late 1980s, with the advent of Integrated Services Digital Network (ISDN) services. More recent technologies, such as asymmetric digital subscriber lines (ADSL), cable modems and FFTB (fiber-to-the-building) have enabled broadband data transfer to consumers.
Development of technologies that allow for higher rates of data transfer has spurred the development of a broad array of digital telecommunications applications, including cellular telephony, video conferencing, digital television and digital radio, among many others.
In selecting a host and hosting package, data transfer considerations are crucial. Websites and applications that offer images, audio, and/or video content require a hosting solution that can accommodate a large amount of data transfer, as exceeding data transfer limits can interrupt service, causing revenue loss and end-user customer frustration.
