• Create an array of tasks and sort them based on priority and start time

• Implement a scheduling algorithm like Round Robin or Priority Scheduling

• Use system calls like fork() and exec() to create and execute processes

• Implement synchronization mechanisms like semaphores or mutexes to avoid race conditions

Static, volatile, const are C keywords used to define properties of variables.

• Static: used to define a variable that retains its value between function calls

• Volatile: used to indicate that a variable's value may change unexpectedly, e.g. in an interrupt

• Const: used to define a variable whose value cannot be changed once initialized

ISR stands for Interrupt Service Routine. It is managed by prioritizing interrupts and handling them in a timely manner.

• Prioritize interrupts based on their importance

• Handle interrupts in a timely manner to prevent delays in the system

• Ensure that the ISR does not interfere with the normal flow of the program

• Test the ISR thoroughly to ensure that it works as expected

• Use appropriate tools and techniques to debug any issu...read more

Mutex is a synchronization mechanism used to prevent multiple threads from accessing shared resources simultaneously.

• Mutex stands for mutual exclusion.

• It is used to protect shared resources from race conditions.

• Mutex provides exclusive access to a shared resource.

• It is used in multi-threaded programming.

• Mutex can be implemented using locks or semaphores.

Insertion in binary search trees involves finding the appropriate position for a new node based on its value.

• Start at the root node and compare the value of the new node with the current node.

• If the new node's value is less than the current node, move to the left child node.

• If the new node's value is greater than the current node, move to the right child node.

• Repeat the comparison and movement until reaching a leaf nod...read more
