Besides these, most DBMSs provide interfacing mechanisms with which developers can implement applications in a general-purpose language (referred to in this context as a host language) and use the latter to invoke whatever operations are supported over the stored data (because they are part of the behavior of either the data types made available by the data model or the application types declared in the application schema). 

The Internet is a world-wide public computer network. The Internet was originally founded by the Department of Defense in the 1970s using transmission control pro-tocol/Internet protocol to connect computers and networks. Since the inception of Hyper Text Markup Language (HTML) in the early 1990s, the Internet evolved from text-based communications platforms to graphically interfaced web pages. HTML fueled the development of the Internet into websites that would be publicly accessible, be hosted via Internet-connected network servers, and allow for other media files rather than mere text to be accessed. 

The USB host communicates with the USB peripheral through the HID device driver. The device driver is a software component that enables an application to access a hardware device. The appHcation software can be developed using any visual language that supports applied programming interfaces. Visual languages like Visual Basic, Visual C- —h, Delphi, Python, etc. can be used for developing application software. 

The writer, or user, of a PC package which is an unsupported interface to software from a major vendor, faces obvious dangers. The vendor of the host system may, maliciously or unknowingly, change minor features of his file structure or command language, rendering the PC interface inoperable.
