Caching
Magento has a very unique way of caching data. This is a logic you need to be familiar with when working with Magento. The cache is updated automatically as Magento is set up, but this can also be done manually if you want to push an update immediately. Go to System > Tools > Cache management to find the overview of caches. Select Flush Magento cache to clear all cache, or you can select just some of the lines to clear the cache of specific data. You can read more about best practices in Magento's own https://docs.magento.com/user-guide/v2.3/system/cache-management.html#best-practices-for-caching

Magento uses full-page caching on the server to quickly display category, product, and CMS pages. Full-page caching improves response time and reduces the load on the server. Without caching, each page might need to run blocks of code and retrieve information from the database. However, with full-page caching enabled, a fully-generated page can be read directly from the cache.

Cached content can be used to process the requests from similar types of visits. As a result, pages shown to a casual visitor might differ from those shown to a customer. For the purposes of caching, each visit is one of three types:

• Non-sessioned - During a non-sessioned visit, a shopper views pages, but does not interact with the store. The system caches the content of each page viewed and serves them to other non-session shoppers.

• Sessioned - During a sessioned visit, shoppers who interact with the store — through activities such as comparing products or adding products to the shopping cart — are assigned a session ID. Cached pages that are generated during the session are used only by that shopper during the session.

• Customer - Customer sessions are created for those who have registered for an account with your store and shop while logged in to their accounts. During the session, customers can be presented with special offers, promotions, and prices that are based on their assigned customer group.

The Magento page cache library contains a simple PHP reverse proxy that enables full page caching out of the box. A reverse proxy acts as an intermediary between visitors and your application and can reduce the load on your server.
