Drivers on the computer is a software component that serves as a communication device between the Operating System and Hardware. Fundamentally, when an application accesses data from a hardware device, it first invokes a function that can be implemented by the operating system. After the operating system successfully reads the message, the operating system then calls the function that can be implemented by the driver. The driver then uses the binary code to command the hardware to perform commands provided by the operating system and retrieve data performed by the hardware. Likewise the next operating system to provide data to the application to work.
Not all device drivers are made by the manufacturer of the hardware in question. However some drivers are designed to meet all hardware requirements in the same scope. This means that drivers can be created by others such as Microsoft can create standard drivers to run keyboard hardware.
Not all device drivers can directly communicate with hardware. This means the corresponding driver can not read data with binary I / O code to read directly the data from a hardware. Fundamentally this type of driver depends on the primary driver that can communicate directly with the hardware in question. This type of driver will manipulate commands to other drivers.
Some filter type driver devices only record I / O operating system commands to the primary driver to read data from hardware directly. Suppose the Dolby digital driver will ask for help to the sound driver to perform commands to the sound card to send a visualization of the sound that can be done by the sound card.
Device Driver on the operating system works directly with Hardware. However there are drivers that work for certain software to work well using binary command manipulation to the processor. These drivers are called Driver Software.
What is Driver Software?
Driver Software is a driver that functions as a communication device between applications with Operating System at Kernel level. Operating System Kernel is a core system that can only be read by a driver with certificate permissions, where the driver can read the core data without having to pass through the operating system encryption system. Unlike viruses on a computer that can breach these permissions, Software drivers access them legally. Software drivers are usually used by Anti-Virus to work.
Driver Software always works in kernel mode. What distinguishes it from device drivers is that device drivers do not always work in kernel mode. Generally device drivers only work in user mode. So the device driver does not require special certificates of the operating system concerned to work properly.....

Useful information. There are third-party developers also that design and develop drivers for different software and hardware. However, the outdated or old systems face the problem of non-availability of drivers for new Operating Systems.
