About Ram :
RAM is an essential part of every computer, because it holds all of the data your computer is currently using. Think of it as your computer’s short-term memory, whereas the hard drive is more like long-term memory. If you use your computer whilst at work though then it might be a good idea to check out something like this least privilege manager software, to make sure that your computer is safe.
When you load a file or run an application, your system’s processor is constantly accessing data from the memory, so the speed and amount of memory you have plays a critical role in your system’s performance.
RAM is temporary working space the computer uses to get work done and access files, this gets emptied when the computer is turned off. The larger the RAM the more work can be done consecutively.
The best way to think of RAM is like a kitchen counter top. The chef (processor) does all his work on the countertop, with the ingredients he has to hand from the fridge (Hard drive).
If you have a lot of counter space, the chef can work on preparing more things at once. If you don’t have enough counter space, the chef can’t work on as many tasks, he has to keep going back to the cupboard to get individual ingredients out… therefore his cooking slows down.
Some programs, like games or design software use a lot of RAM as they are constantly locating many files and data- much like some recipes call for a lot of ingredients. On a small counter it’s harder to fit all the ingredients on.
On computer with less RAM, programs can slow down as they don’t have enough quick access to the vital data they need to function. This is one of the reasons older computers appear to slow down when you put new programs on there. The RAM (amongst other things) required to run new programs is often higher generations progress.
