What are the benefits of caching?

• A. Increases server load
• B. Slows down data retrieval
• C. Reduces load on database and speeds up operations
• D. Eliminates need for database indexing

Answer: (C)

Caching stores frequently requested data in fast, in-memory storage so repeated requests can be served quickly without always querying the database. This reduces the load on the database because fewer queries reach it, and it speeds up overall operations because responses come from the cache with low latency.

Caching doesn’t eliminate the need for database indexing; indexes remain important for efficient data retrieval when the cache misses or for initial data population. It also isn’t accurate to say caching increases server load or slows down data retrieval—when data is cached, access is typically faster, while misses still involve the database.
