For work groups, Switch was designed to improve the performance of the working groups, ensuring the flexibility of 10/100mbps connections. Powerful but simple to use, it allows users to connect any door to a 10Mbps or 100Mbps node to multiply the bandwidth, improve response times and satisfy heavy workloads. 16/100Mbpslo Switch provides 16 doors, all with support for the Nway standard. The doors are able to negotiate both the connection speed in network environments 10base-t and 100base-tx and the full-duplex or HALF-duplex transmission mode. Flow control control control control incorporated in the switch is available in full-duplex mode represents a tool to avoid data loss during transmission. If connected to a network card that in turn supports this functionality, the switch sends signals to the personal computer to notify the overload of the buffer in peak moments. In the face of these signals, the personal computer interrupts the transmission until the switch is again able to accept the data.
