Linux Device Driver Developer Interview Questions and Answers

I have used various Inter-Process Communication (IPC) mechanisms in Linux, including pipes, message queues, shared memory, and sockets.

• Pipes: used for communication between related processes

• Message queues: used for asynchronous communication between processes

• Shared memory: used for fast communication between processes

• Sockets: used for communication between processes over a network

To reverse a singly linked list, iterate through the list and change the direction of pointers.

• Iterate through the list and keep track of current, previous, and next nodes.

• Update the next pointer of the current node to point to the previous node.

• Move to the next node and repeat the process until the end of the list is reached.
