A screenshot is an image of what is visible on a visual output device such as a computer monitor or television.

Usually, this is a digital image created by the operating system or software running on the device, but it can also be a photograph or a recording made by a device intercepting the video output of the display.

In computer programming, an Application Programming Interface (API) is a set of subroutine definitions, protocols, and tools for building application software.

In general terms, it is a set of clearly defined methods of communication between various software components.

A good API makes it easier to develop a computer program by providing all the building blocks, which are then put together by the programmer.

Streaming media is multimedia that is constantly received by and presented to an end-user while being delivered by a provider.

The verb "to stream" refers to the process of delivering or obtaining media in this manner; the term refers to the delivery method of the medium, rather than the medium itself, and is an alternative to file downloading, a process in which the end-user obtains the entire file for the content before watching or listening to it.

A website is a collection of related web pages, including multimedia content, typically identified with a common domain name, and published on at least one web server.

A website may be accessible via a public Internet Protocol (IP) network, such as the Internet, or a private local area network (LAN), by referencing a uniform resource locator (URL) that identifies the site.

A desktop computer is a personal computer designed for regular use at a single location on or near a desk or table due to its size and power requirements.

The most common configuration has a case that houses the power supply, motherboard (a printed circuit board with a microprocessor as the central processing unit (CPU), memory, bus, and other electronic components), disk storage (usually one or more hard disk drives, optical disc drives, and in early models a floppy disk drive); a keyboard and mouse for input; and a computer monitor, and, often, a printer for output.

The case may be oriented horizontally or vertically and placed either underneath, beside, or on top of a desk.
