Q1. What are storage classes
Ans. 
Storage classes in C define the scope and lifetime of variables.
• Storage classes include auto, register, static, extern, and typedef.

• Auto variables are local to the block they are declared in.

• Register variables are stored in CPU registers for faster access.

• Static variables retain their value between function calls.

• Extern variables are declared in one file and can be used in another file.

• Typedef is used to create new dat...read more

Q2. What is use of device drivers
Ans. 
Device drivers are software programs that allow the operating system to communicate with hardware devices.
• Device drivers act as a translator between the hardware device and the operating system.

• They provide a standardized interface for the operating system to interact with different types of hardware devices.

• Device drivers help improve system stability and performance by enabling efficient communication between hardwar...read more
