Is there any requirement of RAM in devices, if yes then what amount of RAM we need and no then why we check only RAM while purchasing new devices.
RAM means Random Access Memory, i.e. RAM provides us a plot to open our tasks.
As we consider an area of 10 sq.ft. is sufficient for playing a game but if i decrease the space to half the game play will not be smooth or if i double the area originally i have used it will be much more but thats not good for playing as players will get tired soon.
So according to the example RAM behaves. Every task requires different RAM space but that is managed by system. But on other hand more the RAM more task can be opened.
RAM are of two types as Static RAM or Dynamic RAM.
