What is caching? Learn this common and complex technology

[mouakter13]

The dissemination of information on the web requires processing power and time. Data has to travel from one server to another. Using caching reduces this time and resource usage.

The answer to what a cache is depends on the context. In general, a cache is a way to quickly save and retrieve frequently used data. Cache management, especially when using WordPress, can be the difference between a site that runs quickly and smoothly and a frustratingly slow site.

This post will answer the question “What is cache?” and provide some ideas on how to manage yours.

What is cache?
How web caching works.
How web caching works.
Cache takes data processed by an application and stores it for later use. It doesn't have to be in the browser per se , but you'll see websites and their underlying technology use cache a lot. "Cache" is the term for the process of storing and retrieving saved data.

The cache usually includes two elements:

The caching software itself performs the process and transfers it between the other elements.
Random Access Memory (RAM) and In-Memory engines. They store data passed through cache technology.
These elements need to be of high quality and work together. Slow RAM will not be able to retrieve data quickly enough for the software to use it efficiently.

A cache is almost necessary for most web applications, given the large file sizes of pages. A solid implementation can give you back precious seconds in some cases. A user who comments that a site thailand whatsapp number data loads quickly is paying an indirect compliment to the caching software at the heart of the website's server.


How caching can help optimize websites
Computer technology is constantly expanding. In other words, memory, hard drive space, and other such computing processing elements are increasing in size at a rapid rate. Gone are the days of 64 KB of RAM in our personal computers; now it is typical to see Gigabytes (GB) of RAM. Some of the latest Apple MacBooks can even accommodate 64 GB of memory.

Websites are also becoming heavier due to the demands that modern web development and related technologies place on the code on the site. Not only is more processing power needed for the end user, but also a more robust server and the technology to accommodate it. Without memory (and without cache), loading speeds slow down.

Therefore, search engine optimization (SEO) has long recognized that page speed is a primary factor in website ranking . Although the exact details are not known, the ranking factors that play a role in a site's positioning in search engine results pages (SERPs) include references to site speed .
