RAM stands for random access memory. This tells you any part of the data it stores can be accessed directly. The phone doesn’t have to scan through sequentially-stored data as you might do with a CD, an old tape cassette or, most importantly, a hard drive. It’s effectively instant-access.
The RAM is a temporary memory, the data of which will be lost on restarting, unlike internal storage. But you can recall those files or apps in RAM swiftly when compared with SD card storage. As a result, calling apps from RAM drains less battery juice.
If the CPU is a chef, the cache is their chopping board, RAM the kitchen cupboards, and general storage the supermarket 15 minutes down the road. That gives you an idea of how impossibly slow a phone would be if it really only used the kind of ‘memory’ we install apps onto.
IF RAM WORTH IT??
Devices with more RAM can run more complex software and multiple applications at the same time.
The RAM is responsible for all the apps you can run in the background & the amount of RAM determines how much or how many apps you can run in the background at a time which your phone's RAM can accommodate. So, when you do something on your device it happens in RAM. More RAM implies you can run more apps at a time.
RAM is also what holds the data that enables multi-tasking. Some mobile devices now offer real Windows-style multi-tasking, where two apps are running on-screen at once. A good amount of RAM is crucial for this.
RAM is also what lets you flick between apps without having to start from scratch each time. Even if an app isn’t actively doing anything in the background, RAM is used to create a saved state that the phone can zap back into as if you’d never left.
By all this we can say it is worth it.
NOTE - “Greater the RAM, Greater the performance”, is not true
It may show some results accordingly, but that’s not what exactly happens. The performance mainly depends on the frequency and data transfer rate. More the frequency, faster the data transfer, faster will the processed data be displayed!
HOW FAST RAM IS??
It has extremely fast data transfer speed varying from 2Gbps to more than 30Gbps (depending on DDR of the RAM).
LESS RAM IS REALY A PROBLEM
the smartphones have many apps running in the background hance those background apps consume all the RAM to perform their tasks and hence no RAM will left. In that situation when you open a new app it may not function as it has no RAM left to perform it's function and hence the app closes automatically.
HOW RAM WORKS
When you download and install an app, it gets stored on your permanent storage (that’s internal or external SD card). Whenever you execute the same, it is shifted to RAM. (All the live running processes run on RAM). Even if you close that particular app after a while, Android will not remove it from the memory (I mean RAM), so that you can recall it faster at any time you want. The processes that stay on RAM even after the closing is called background processes.
WHAT I THINK
Demand for RAM isn’t going to get any less.
