Meaning of Cache


Anyone who uses a computer, laptop or smartphone has probably heard that they should clear the cache. However, many users are not even aware of what the cache is. The possibility of clearing the browser cache depends on the web browser used or the smartphone app.

  • The cache is a fast buffer memory.
  • The cache can be a piece of hardware or it can be implemented by software.
  • Every internet browser has its own method of clearing the cache.

What is the cache?

The cache is a fast buffer memory in which data from websites, for example, is temporarily stored. These data then no longer have to be obtained from the Internet when the page is reloaded, but come directly from the computer. This speeds up the loading of pages considerably. The cache can be implemented as hardware memory. It can also be a software solution. As a rule, the user does not notice any difference.

Data in the browser cache

Files and data that are frequently accessed are stored in the cache. The data stored there include, for example, cookies , scores for online games , browser history, and entire websites. Over time, a lot of data accumulates there, which delays the function. Therefore the cache should be cleared from time to time.

Clearing the Cache

If the user manually clears the cache, the information stored there will be lost. You can therefore choose whether all or only certain stored information should be deleted. For example, if the user deletes all cookies, he has to log in to the website again. The scores of online games are also lost as a result. The browser history can also be deleted. In this way, the user obliterates his online traces for other users of the computer. After clearing the cache, the pages take a little longer to load. But then all the information is really up-to-date.
