The Esential Drivers A Computer Needs
A common piece of software that is often overlooked is the software driver. These drivers are designed to allow an external piece of hardware, such as a printer, to integrate with the main computer unit. A driver facilitates communication between the software application that needs to use a device and the device itself. It can be thought of as a bridge that closes the gap between applications and external hardware devices.
When a computer software program calls for a certain function of the device, this invokes a specific routine in the driver which then issues the proper command to the device. The device then sends the requested data back to the driver, which in turn communicates that back to the application.
