The Empty TitlesTranscoding is the direct digital-to-digital conversion of one encoding to another. This is often done in cases where a target device does not support the format or has limited storage capacity that mandates reduced file size, or to convert incompatible or obsolete data to a more supported or modern format. When transcoding one lossy file to another, the process always introduces generation loss (albeit perhaps imperceptible).
In computing, a mirror is an exact copy of a data set. On the Internet, a mirror site is an exact copy of another Internet site. Mirror sites are most commonly used to provide multiple sources of the same information, and are of particular value as a way of providing reliable access to large downloads. Mirroring is a type of file synchronization.
A live mirror is automatically updated as soon as the original is changed.
In computer networks, a proxy server is a server (a computer system or an application program) that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server evaluates the request according to its filtering rules. For example, it may filter traffic by IP address or protocol. If the request is validated by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client. A proxy server may optionally alter the client’s request or the server’s response, and sometimes it may serve the request without contacting the specified server. In this case, it ‘caches’ responses from the remote server, and returns subsequent requests for the same content directly
