Streaming

Definition

Streaming refers to the process of transmitting or receiving data (most commonly audio and video) over a computer network as a steady, continuous flow, allowing playback to proceed while subsequent data is received. This enables users to view or listen to content instantaneously, rather than waiting for an entire file to be downloaded before it can be accessed.

Netflix: One of the most popular streaming services, offering a vast library of TV shows, movies, and documentaries available for real-time viewing.
Spotify: A leading music streaming platform providing access to millions of songs, albums, and podcasts.
YouTube Live: Enables real-time broadcasting for content creators, allowing viewers to watch live events as they happen.
Twitch: A live streaming platform mainly focused on video game live streaming, including broadcasts of eSports competitions.
