What is the purpose of a caching system and what are its advantages?

The caching system is designed for temporary storage of frequently requested data to speed up access to it and reduce the load on the main storage or computing resources.

Advantages of caching:

• Faster application response times due to quick data access
• Reduced load on the database or external services
• Increased system scalability

For example, a web application can cache the results of complex database queries to avoid executing them every time a user accesses the system.
