What are the different types of caching and how do they differ?

There are several types of caching, including memory caching, disk caching, and distributed caching. Memory caching stores data in RAM for quick access, while disk caching uses storage devices. Distributed caching spreads data across multiple servers.

Can you explain memory caching in more detail?

Sure! Memory caching stores frequently accessed data in the system's RAM, which allows for faster retrieval compared to fetching from a database or disk. This is particularly useful for applications that require high performance.

What about disk caching? How does it work?

Disk caching temporarily stores data on a disk drive to speed up access times. It acts as a buffer between the main storage and the CPU, reducing the time it takes to read data from slower storage.

And what is distributed caching?

Distributed caching involves multiple cache servers that work together to store data. This approach improves scalability and reliability, as it can handle larger datasets and distribute the load across several machines.
