1. An Ethernet network interface card being capable of an automatic transfer mode switch, comprising:
- a detecting module to detect the network condition and generate a detecting result; and
a deciding/switching module to decide a network cable transfer mode according to said detecting result, wherein if said detecting result shows that a two-way network cable transfer mode for data transfer is needed under said network condition, said deciding/switching module performs a one-way/two-way network transfer mode switch process;
wherein if said detecting result shows that said two-way network cable transfer mode for data transfer is not needed under said network condition, said deciding/switching module does not perform said one-way/two-way network transfer mode switch process.
