¿Cómo funcionan las redes centrales??
Las redes concentradores son un tipo de red informática que conecta múltiples dispositivos o nodos para compartir recursos., información, y servicios. Una red central se compone de uno o más centros (puntos de conexión centrales) y todos los demás dispositivos conectados. Cada dispositivo de la red está conectado directamente al concentrador., que actúa como punto central para la transmisión de datos. Los datos se envían de un dispositivo a otro a través del concentrador y se pueden intercambiar entre dos dispositivos conectados al concentrador.. En una red central, todos los dispositivos comparten ancho de banda entre sí, lo que significa que todos los recursos están disponibles para cualquier dispositivo conectado en cualquier momento. Sin embargo, Esto también significa que hay menos capacidad general en la red ya que cada nodo tiene que competir por el acceso a los mismos recursos.. Tal como, Es importante asegurarse de que su red tenga suficiente capacidad para garantizar el máximo rendimiento.. Además, Este tipo de arquitectura de red suele ser más adecuada para redes más pequeñas, ya que las más grandes pueden sobrecargarse rápidamente y ralentizar el rendimiento general..
