Difference Between Device Driver And Application Programming
At present, the device driver job is considered one of the highest-paid jobs. But many people get confused about whether the device driver and application programming are the same or not. Well, let me explain to you in a simple way.
The major difference between application programming and device driver programming is that when you are working on device driver programming or development, you are directly talking to hardware by utilizing your code, which means you normally write and read registers.
While device driver programming you need an excellent knowledge of microprocessor or microcontroller architecture, protocols, peripheral interfaces, ability to understand the datasheets, programming the microcontroller, knowledge about API, kernel-mode privileges, device driver structure, interfacing with device drivers from applications, DMA programming, and some other concepts like interrupt handlers.
Well, guys, you require a good or excellent amount of programming, debugging, OS internals, hardware, and system-level knowledge.
Application programming is basically creating or developing a logic of business by utilizing some programming languages based on the requirement. Here you have to be excellent in the specific programming language with an excellent knowledge of logic building and debugging.
There are numerous tools and programming languages to develop or create application programs on various platforms but device drivers are basically created or developed by utilizing the C language.
Difference Between Device Driver And Application Programming
| Different Terms | Application Programming | Device Driver Programming |
| Usage | It is utilized in each hardware or electrical device that contains an embedded system | It is utilized when two devices are connected |
| Dependency | It will not rely on any device, it takes care of the internal functions of the hardware | It relies on devices |
| Storage Place | It is stored in the volatile memory of the hardware | It is stored in memory space allocated by the operating system |
| Creation | When hardware is manufactured, it is coded in the volatile memory of the hardware | To help communicate with other devices, it is developed by the manufacturer |
| Alternation or installation | Before application program was unchangeable, but now it is possible to change the application program | Through the internet, it can be easily updated |
| Functions | It manages the internal functions of the hardware. It manages basic input and output functions and it is coded in hardware | Between hardware and OS, it acts as an intermediary. |
| Examples | The best example we can consider is the BIOS (basic input-output system) | Here we can consider the graphics driver that communicates with your OS to control your video card |
| Purpose | It defines the function ability of the hardware | It helps in the communication between hardware and operating system. |
