Hey, guys we all know about RAM which stands for Random Access Memory. Well, that's a mouthful words. So , what actually it is??
So , suppose you are working in an office and messing with a lots of files and those files are inside an another room. So , the file which you need to work on , you will simply go to the room where all files are and will take that particular file only and put it on the desk and start working on your assignment.
So, now suppose to finish an assignment , you are going to need more than one file. So , you will fetch the room where files are and take those all files and put them on the desk and take those files one by one in order to finish the assignment. Now , if your desk has large area then it means it can hold more files at a time. Now, when you are done with those files then you will simply put them all in that room where files are kept. So , the RAM works like that i.e, suppose the room is your storage(internal memory, sd card etc) and the desk is your RAM. So , ram is a very fast memory and cost to manufacturing a 1 GB ram is more than a 16 GB sd card or pen drive.RAM works with cpu and in order to work with cpu , it has to be match with the speed of cpu and that's why RAM is very much faster than hard disk , pen drive, sd card, dvd, etc. So , if you install a game in your phone or pc then though it stores inside your sd card or internal memory or hard disk but when you click on the game to play with , so for the time being , it will come into action inside the ram until you are playing the game in order to transfer information between the cpu and ram.So , depending upon how much ram you are having , you can run more and more application at a time. So, having more ram is an extra benefit for multitasking purpose. So , today at least 2 GB ram is sufficient to run any application but having more ram is best for some future's application.So , for multitasking purpose , 2GB ram is the minimum requirement.
MISCONCEPTION BEHIND RAM
Some people thinks that after rooting the smart phones , they can increase their ram. So , it's entirely a misconception. Yeah , there are some apps which can convert your external or internal memory into ram but can it really work as your ram?? No , it can not. Speed of ram is very much faster in order to communicate with cpu to transfer information whereas on the other hand speed of external ram or internal memory can never ever match with the speed of your inbuilt ram of your phone or ram of your pc. Some people think that using ready boost they can use pen drive as a ram but its not 100% true due to a huge speed difference between ram and a pendrive or external storage. If you use an external storage as a ram then it will slow down the speed of your phone or pc rather then increasing the speed.
RAM has speed in MHZ which divides it into category of DDR2 or DDR3 and so on. So, having more ram with high frequency is good for you.
DDR3 has more speed and less power consumption than DDR2.Similarly , DDR4 has more speed and less power consumption than DDR2 and DDR3. A DDR3 ram has minimum speed that is equal to maximum speed of DDR2.If you are having 8 GB of ram in your pc and you are thinking to take whether a single stick ram of 8 GB or a dual stick of 4 GB then i will suggest you to take dual sticks of 4 GB ram because though you will have 8 GB total but the speed will be enhanced due to dual sticks ram. It is similar like a a double hole in tank can empty the tank more fastly than a single hole.
So, guys i think you now do have basic ideas about ram and common myth regarding ram. I will be back soon with another technical concept like this.
