Binary search divides the search space in half with each iteration, resulting in O(log n) time complexity on sorted data.
Hash tables use hash functions to map keys to indices, providing O(1) average-case lookup, insertion, and deletion operations.
AWS Auto Scaling automatically adjusts the number of EC2 instances based on demand metrics like CPU utilization or network traffic.
Linked lists require extra memory for storing pointers/references in each node, making them memory-inefficient compared to arrays.
The Network Layer (Layer 3) handles routing, IP addressing, and logical path determination for data packets.
Indexes create a faster lookup structure similar to a book's index, enabling rapid data retrieval without full table scans.
Merge Sort maintains O(n log n) complexity in all cases and is stable, making it ideal for sorting large datasets.
Normalization removes data redundancy and prevents update, insertion, and deletion anomalies through organized table structures.
INNER JOIN returns only rows that have matching values in both tables, making queries more efficient for specific requirements.
Atomicity ensures that a transaction is treated as a single unit - either all operations complete or none do.
