Additional RAM

RAM stands for Random-Access Memory. Computer RAM is essentially short term memory where data is stored as the processor needs it.
Whenever an app is executed on a server, it's loaded into the physical memory. In case you run a resource-demanding script, or if you simply add more scripts on your websites and you get plenty of visitors, you might encounter a case where your VPS has insufficient memory to run all the apps and freezes as a result, which means your websites will stop operating properly and that the website visitors will start seeing error messages. To avoid such a scenario, you can take advantage of the RAM upgrade that are offering and increase the amount of physical memory available without changing the entire plan. In this way, you can pay just for the system resources that you actually need and not for additional disk space or higher Processor speeds which you will not really use, for instance. With the upgrade, you can ensure the faultless functioning of your websites, which also means a better experience for your visitors.
