A media server is a computer system or software that stores and manages digital media files, such as videos, music, and images. It allows users to access and stream this content over a network, making it easy to share media across multiple devices like smart TVs, smartphones, and tablets. Media servers can be used in homes, businesses, and even for large-scale events. These servers often support various formats and protocols, enabling compatibility with different devices. Popular examples of media server software include Plex, Emby, and Jellyfin. They provide features like transcoding, which adjusts media files for optimal playback on different devices.
