What is the first valid address on a subnet?
Depends on the subnet.
For the subnet of 192.168.1.0, the first usable IP address is 192.168.1.1. This is typical of a default wireless router setup.
Valid usable IP addresses under this scenario is 192.168.1.1 to 192.168.1.254.
Like most drivers, they are the software interface between the computer and the device. In the case of the network card, it allows the computer's operating system (Windows/Linux/etc) to talk to the network card, and vice-versa.
Without the drivers, the operating system would not be able to use the network card for what it was intended for. Since each manufacturer makes their own network cards, each one might have their own set of drivers. Some are interchangeable, but most are not.
