The speed of data transfer is limited by the connection type, cabling, and maximum speeds that your server and network can support.
The connection type can be 10BASE-T, 100BASE-T, or 1000BASE-T, which have a speed of 10 Mbps, 100 Mbps, or 1 Gbps respectively.
The type of cable that you use directly limits the speed that you can use to transmit and receive data.
The maximum line speed of your server is also affected by the type of input/output adapter that you are using.
Depending on your server’s capabilities and the duplex mode of the network interface to which you are attaching, you can use either full duplex or half duplex.
Half duplex mode is restricted to one-way communication. It cannot transmit and receive data at the same time. Full duplex mode sends and receives data simultaneously.
