About Google Cache Checker

How can you define Google cache? It may seem to be quite uncommon for them who are not aware of the term cache. So, it’s better to first define the term cache before going on to describing Google cache. Here is a short definition on the cache. It can be defined as software or hardware component that is used as data storage for future use is known as the cache. By this process, the future request for the data can be even faster than usual. This data that are fetching from the cache is generally stored through earlier computation. It can also be the duplicate data that are stored elsewhere. When a data request is fulfilled in the cache, the cache hit takes place whereas it is said to be cache miss if and when the cache is unable to provide the requested data. Recomposing or reading a data from a slow store can be slow whereas fetching a data from the cache is much faster through the use of cache hits. The system will perform more efficiently through the use of cache where more request can be done. The cache should be small in order to have an efficient and cost effective use of data. Caches are very useful and over the years have proven their needs in computing. It is seen that in the typical application of computer there is an access pattern that has a reference locality. If data request occurs twice for a data that is requested recently then temporal locality exhibit in the case of access pattern. If the data is the store close to the physical that has been requested, then it is known as spatial locality.

The cache can be differentiated as Hardware cache and as Software caches. To go into further detailing, some of the examples of hardware caches are;

  • CPU cache – memory that is present close or on the CPU operates much faster. D-cache, I-cache can be the example of specific function cache.
  • GPU cache – GPU stands for graphics processing units. GPU cache has a texture cache that is read only.
  • DSPs- Also known as Digital signal processor includes cache set that is similar to the CPU. One example of DSPs can be Qualcomm Hexagon.
  • Translation Lookaside buffer- At the time of fetching the entries of page table from that of the main memory, a special type of cache is needed that is known as the translation lookaside buffer that is used in virtual address result recording to translation of physical address.

Some of the examples of Software caches are;

  • Disk cache – Hardware generally manages the CPU caches but at the same time a number of other caches is also been look after by the software. Disk cache is managed by the kernel of the operating system. An example of disk cache can be page cache.
  • Web cache – In order to store previous responses from the web servers like images and WebPages, web caches is being used. Web proxy and web browsers generally use this type of web caches.
  • Memoization – It can be termed as the optimization technique that is used to store function calls resource consuming results in the lookup table and thus allows the subsequent calls to use those results and also avoids repetition of data.

Some other type of caches can be DNS daemon cache, Client-side network file system cache, cache, Database caching and distributed cache.

What is Google cache?

Google stores page copy or a snapshot as backup known as Google cache. While examining each page Google takes a snapshot of it and that version of the page is a stored as a backup. This version is used by Google to see whether the page satisfies the query or not. Other web servers are mainly slower than that of the Google server. So, it is much faster to access the cached version of the page than that of the page itself. The search result that we search for always has cache link in it. If you click on the link, it will take you to the catch version of the page for that web page. It will not take you to the current version of the web page. Google cache is mainly used in cases where the original page is unavailable due to one of the reasons like internet congestion, the website is slow and the web page is being removed by the owner of the page. If a site needed to be registered or subscribed then also the cache version is being used for the particular site. Cache version of a page can be accessed faster than the page itself. You need to look at the cache version of the page if it is found that Google is returning the link to a page that is not an answer to your query then or you are unable to find the information that you seek for that current page version.

What is Google cache checker?

This checker delivers an analytic report. It shows the status of the page as cached or not cached. This checker gives you the opportunity to test 20 links at a time that are provided in the separate line.
