útválasztó

The term "útválasztó" is a Hungarian word that translates to "router" in English. In the context of computer networking, an útválasztó is a hardware device responsible for forwarding data packets between computer networks. It operates at the network layer (Layer 3) of the OSI model.

An útválasztó examines the destination IP address of incoming data packets and uses its routing table to determine the most efficient path for that packet to reach its destination. This routing table is a set of rules that dictate how to forward packets based on their destination network. Útválasztók connect different networks, such as a home network to the internet, or different segments within a larger corporate network.

They play a crucial role in the internet's infrastructure, enabling communication between diverse networks worldwide. Home útválasztók are commonly used to share an internet connection among multiple devices and provide Wi-Fi access. In larger networks, more sophisticated útválasztók manage complex traffic patterns and ensure reliable data delivery. Without útválasztók, data packets would have no way to navigate beyond their local network.
