What is buffer cash and log cache in sql server?..

Answer / Kumar Phanishwar

"Buffer Cache stores data pages from disk in memory, reducing the number of disk I/O operations. It improves query performance by keeping frequently accessed data close to the processor for quick access. Log Cache holds the log records that are waiting to be written to disk. It ensures data consistency during transactions and recovery operations."
