Network layers are a hierarchical way of organizing communication protocols.

• Network layers provide a modular approach to networking.

• Each layer has a specific function and communicates with adjacent layers.

• The OSI model has 7 layers, while the TCP/IP model has 4 layers.

• Examples of layers include the physical layer, data link layer, network layer, transport layer, and application layer.

Deadlock is a situation where two or more processes are unable to proceed because they are waiting for each other to release resources.

• Occurs in multi-threaded/multi-process environments

• Can lead to system freeze or crash

• Prevention techniques include resource ordering and timeouts

• Example: Process A holds resource X and waits for resource Y, while Process B holds resource Y and waits for resource X

Paging and Segmentation are memory management techniques used by operating systems.

• Paging divides memory into fixed-size pages and stores them in physical memory.

• Segmentation divides memory into logical segments and stores them in physical memory.

• Paging allows for efficient use of physical memory and reduces fragmentation.

• Segmentation allows for protection and sharing of memory between processes.

• Examples of operating s...read more

Reverse a linked list using iterative and recursive methods.

• Iterative method involves traversing the list and changing the pointers to reverse the order.

• Recursive method involves calling the function recursively on the next node and changing the pointers.

• Both methods have O(n) time complexity and O(1) space complexity.

• Example: 1->2->3->4->5 becomes 5->4->3->2->1.

Clone a linked list with a random pointer.

• Create a new node for each node in the original list.

• Use a hash table to map the original nodes to their clones.

• Iterate through the original list again and update the random pointers of the clone nodes.
