The World Wide Web (WWW) is an information system where documents and other web resources are identified by Uniform Resource Locators (URLs) and are accessible over the Internet. It operates on a client-server architecture using the Hypertext Transfer Protocol (HTTP). Users access web pages via browsers, which interpret HTML code to display text, images, and multimedia content linked together through hyperlinks, forming a global information space.

Digital audio represents sound waves as a sequence of discrete numerical values. The process involves sampling the continuous analog signal at regular intervals and quantizing these samples into binary data. Key parameters influencing quality include the sampling rate (e.g., 44.1 kHz for CD quality) and bit depth (e.g., 16-bit). Common formats include uncompressed WAV and compressed formats like MP3, which use psychoacoustic modeling to reduce file size while maintaining perceived audio fidelity.
