Temporary storage used to store copies of web pages or data to reduce load times. Caching may be configured to expire after a specific amount of time to ensure users get updated content. You can also manually “flush” the cache to force a fresh copy of the stored content.

1. Browser Cache:
   • When you visit a website, your web browser saves certain elements, such as images, stylesheets (CSS), and JavaScript files, in a local cache on your device. This way, if you revisit the same website, the browser can load these elements from the local cache rather than downloading them again from the server.
     
2. Server Cache:
   • On the server side, caching stores the results of expensive operations, like rendering a webpage or querying a database, so they can be quickly retrieved for future requests.
     
3. Content Delivery Network (CDN) Cache:
   • CDNs also cache content, such as images and scripts, across their network of servers worldwide.

Types of Cached Content:

• Static Content: Images, JavaScript, and CSS files are often cached because they do not change frequently.
  
• Dynamic Content: Sometimes, parts of a website that change frequently can still benefit from short-term caching, such as a homepage with frequently updated news.

Benefits of Caching:

• Reduced Load Times: Since data is retrieved locally or from a nearby server, caching significantly speeds up the loading process.
  
• Lower Bandwidth Usage: Caching reduces the need for repeated data transfer between the server and the client, which saves bandwidth.
  
• Reduced Server Load: Caching reduces the number of requests the server has to handle, improving overall performance and stability.
