This is the simplest way I can put it: RAM is temporary memory. It serves as temporary storage for files in your operation system, applications, internet browser, etc. Unlike your hard drive, the data stored on it goes away after shutting down your computer. Hope this helps
Think of ram as a holding tank for data that is fed into the cpu , it is there because the cpu prefetches the data and keeps it there for fast access instead of going to the HDD and waiting for the spinning platters to give the data. It is not permenent storage just temporary.
How does RAM affect performance? Like how different would your computer be with those 8gb rams compared to the lower gb rams
You can have more things open at once and still have you computer run smoothly. Some examples of this would be having like 15 internet tabs open at the same time, a program with a bunch of plugins running, or just a lot of applications running at once.
