Operating system is also known as OS in short. Above Diagram shows that OS is the intermediate between User and hardware.

Operating system helps to access the hardware like CD-ROM, Hard Disk, Speaker, Touch pad, Mouse etc.

 

In the Accessing of hardware component, There will be Driver  which helps to access the hardware component.

For example: The driver of touchpad, driver of mouse, display adapter etc. the name of driver are different  different so I not mention driver name.

SO ,basically driver is also a software that helps to access the hardware and also software component.(why also for software this is showing below).

 

Above diagram shows that Software is also access by the their own driver. Here  Sdk is the driver which help to acess the software. For Example :Before we compiling java program we need to sdk of java which basically helps to access the java program. So, we saw that Driver is most important software which helps to access the hardware and software component.
