What is a driver?
A device driver is a software program that manages communication between your computer and a hardware device. Devices like keyboards, mice, disk drives, and printers all use a software driver to interact with the operating system and other software applications. When you buy an operating system like Microsoft Windows XP, many device drivers are built into the operating system. However, if you buy a new type of device that the operating system did not anticipate, you’ll have to install a new device driver. A device driver essentially converts the more general input/output instructions of the operating system to messages that the device can understand.
The driver converts DC power (batteries) to 120 volts ac, and provides a higher frequency of approximately 2000 Hertz (cycles per second) to light up the lightwire. Drivers come in two forms, CASE drivers that have built in battery compartments and CUBE drivers that have a battery connector. CASE drivers use AA, AAA or 9 volt batteries depending on the design.
The software that allows an Ethernet card in a computer to decode packets and send them to the operating system and encode data from the operating system for transmission by the Ethernet card through the network. By handling the nitty-gritty hardware interface chores, it provides a device-independent interface to the upper layer protocols, thereby making them more universal and [allegedly] easier to develop and use.
