Each TiVo Mini is designed to serve one host device at a time for streaming and recording.

Informatica Router and Filter are both transformation components used to manage data flow in an ETL process, but they serve different purposes. The Router transformation allows you to route data into multiple output groups based on specified conditions, enabling different processing paths for different data subsets. In contrast, the Filter transformation is used to exclude rows from the data flow based on a single condition, passing only the rows that meet the criteria to the next stage. Essentially, Router offers multiple outputs for various conditions, while Filter simply includes or excludes data based on a single criterion.

A star LAN (Local Area Network) is a network topology where all devices are connected to a central hub or switch. This central device acts as a repeater for data flow, allowing communication between the connected devices. The star configuration is popular due to its simplicity and ease of troubleshooting; if one connection fails, it does not affect the entire network. However, if the central hub fails, the entire network becomes inoperable.

A signaling gateway in a Public Switched Telephone Network (PSTN) serves as a bridge between traditional circuit-switched networks and packet-switched networks, such as Voice over IP (VoIP). It converts signaling protocols, like SS7 used in PSTN, into IP-based protocols, enabling communication between different network types. This allows for the integration of voice, data, and multimedia services, facilitating interoperability and enhancing the efficiency of telecommunication systems.
