Caching is a technique used to store copies of frequently accessed data in a temporary storage location, called a cache. This helps reduce access time and minimize the load on your backend systems, resulting in faster response times for users."

Types of Caching
1. In-Memory Caching (Redis, Memcached)
"In-memory caching stores data in the system's main memory (RAM) for super-fast access. Tools like Redis and Memcached are commonly used for in-memory caching because they provide extremely fast read and write speeds."


2. Browser Caching
"Browser caching stores static assets—like HTML, CSS, JavaScript, and images—directly in a user’s browser. This helps reduce the need to download the same files each time a user visits your website, which speeds up page load times."


3. CDN Caching
"CDN caching uses a Content Delivery Network (CDN) to cache copies of static content like images, videos, and scripts across multiple servers around the globe. This means users can retrieve content from a server that is physically closer to them, reducing latency."
