Ethernet switch facts for kids
An ethernet switch is a device used to build a network connection between the attached computers (allows computers to talk to each other). It differs from an ethernet hub: While a hub will send incoming data packets to all ports, a switch understands the packets' addressing scheme and will send any data packet only to its destination port, thus limiting the number of collisions (data sent at the same time).
