Oracle Server Technology Interview Questions, Process, and Tips

To solve question 1 with O(n) time complexity, iterate through the array once. To solve with O(logn) time complexity, use binary search.

• For O(n) time complexity, iterate through the array once and perform the required operations.

• For O(logn) time complexity, use binary search to find the desired element or perform the required operations.

• O(n) time complexity is generally faster than O(logn) time complexity for smaller i...read more

UNIX OS uses a dynamic memory management scheme to allocate and deallocate memory efficiently.

• UNIX OS uses virtual memory to provide each process with its own address space.

• The memory management scheme includes techniques like paging and segmentation.

• Paging divides memory into fixed-size pages and maps them to physical memory.

• Segmentation divides memory into logical segments of varying sizes.

• UNIX OS uses demand paging ...read more

The data structure for efficient implementation of cache level memory is a multi-level cache hierarchy.

• Use a multi-level cache hierarchy with different levels of cache (L1, L2, L3, etc.)

• Each cache level should have a smaller size and faster access time compared to the previous level

• Implement a cache coherence protocol to ensure consistency between different cache levels

• Use a replacement policy (e.g., LRU - Least Recent...read more

Pre-order traversal of a BST iteratively

• Create an empty stack and push the root node onto it

• While the stack is not empty, pop the top node and print its value

• Push the right child onto the stack if it exists

• Push the left child onto the stack if it exists

ACID properties are a set of characteristics that ensure reliability and consistency in database transactions.

• ACID stands for Atomicity, Consistency, Isolation, and Durability.

• Atomicity ensures that a transaction is treated as a single, indivisible unit of work.

• Consistency ensures that a transaction brings the database from one valid state to another.

• Isolation ensures that concurrent transactions do not interfere with ...read more

Mutex and semaphores are synchronization mechanisms used in multi-threaded environments.

• Mutex is used to provide mutual exclusion, allowing only one thread to access a shared resource at a time.

• Semaphore is used to control access to a shared resource by multiple threads, allowing a specified number of threads to access it simultaneously.

• Mutex is binary, meaning it has only two states: locked or unlocked.

• Semaphore can h...read more

To find the nth node in a linked list, iterate through the list until reaching the nth node.

• Start at the head of the linked list

• Iterate through the list, moving to the next node each time

• Stop when reaching the nth node
