Comment fonctionnent les réseaux hub?
Les réseaux hub sont un type de réseau informatique qui connecte plusieurs appareils ou nœuds afin de partager des ressources., information, et services. Un réseau de hubs est composé d'un ou plusieurs hubs (points de connexion centraux) et tous les autres appareils connectés. Chaque appareil du réseau est connecté directement au hub, qui fait office de point central pour la transmission des données. Les données sont envoyées d'un appareil à un autre via le hub et peuvent être échangées entre deux appareils connectés au hub.. Dans un réseau hub, tous les appareils partagent la bande passante entre eux, ce qui signifie que toutes les ressources sont disponibles à tout moment sur n'importe quel appareil connecté. Cependant, this also means that there’s less overall capacity on the network as each node has to compete for access to the same resources. En tant que tel, it’s important to ensure that your network has sufficient capacity in order to ensure maximum performance. En outre, ce type d'architecture réseau est généralement mieux adapté aux petits réseaux, car les plus grands peuvent rapidement devenir surchargés et ralentir les performances globales..

Does a network hub affect speed?

Network hubs can have an impact on the speed of a network, as they do not have the capability to prioritize traffic between devices. This means that all connected devices share the same bandwidth, reducing overall network speeds when multiple devices are in use simultaneously. En plus, data must be sent to all connected devices even if only one device needs it, further slowing down communication times. While not ideal for modern networks, some applications such as gaming or streaming may still benefit from using a network hub instead of a switch.
