Memory caching is used to improve what?

• A. Increase Security
• B. Improve Performance
• C. Alter IP Addresses
• D. Compress Images

Answer: (B)

Memory caching speeds things up by keeping recently used data in fast, small storage so the system can access it quickly instead of fetching it from slower memory or a disk. When that data is needed again, it can be retrieved from the cache in a fraction of the time, lowering latency and boosting overall performance. A browser cache, for example, stores images and files to load pages faster on subsequent visits, and a CPU cache helps programs run more efficiently. Caching isn’t primarily about security, altering IP addresses, or compressing images—the main goal is to improve performance.
