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. driver robot

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.

These little drivers also have the ability to request certain commands or functions in return from the application that initiated the "call" to the device. With this constant back and forth communication, it is essential that a driver is running the most current available version of both the software application and of the driver itself.

Some of the common device drivers that you probably have on your pc are the small programs that came with your printer, your digital camera, your cell phone, any Bluetooth device that you have and hard drives that are removable. Without the right device driver you will find it virtually impossible for any of these external tools hardware devices to be recognized by the operating system, let alone function correctly.
