DO YOU WANT TO KNOW MORE ABOUT RAM HERE IS ALL THE INFO YOU NEED ABOUT RAM INCLUDING ITS EFFECT ON THE SPEED OF COMPUTER BUY INCREASING SIZE OF RAM .

What is RAM?

Lets do it in a bullet points system:--

·        Its full form is random access memory.

·        It is form of main memory.

·        It is a volatile memory i.e the memory stored in RAM gets deleted after the system is turned off.

·        It is used to store working data and machine code.

·        It can read and write in almost same times which is better then hard discs , CD-RWs , DVD-RWs which takes more time in reading , writing as they have limitations such as media rotation speeds and arm movements.

More about RAM

In todays world  RAM takes the form of integrated circuit (IC) chips with MOS (metal-oxide-semiconductor) memory cells. RAM is normally associated with volatile types of memory (such as DRAM modules), where stored information is lost if power is removed, although non-volatile RAM has also been developed .

TYPES OF RAMs

The two main types of volatile random-access semiconductor memory are static random-access memory (SRAM) and dynamic random-access memory (DRAM).

Now the main question comes does more RAM means faster computer ?

This myth is half and true and half false you can say more of its side is over false. If you are a light computer user you can work with 4 gb of RAM , but if you are a moderate one you can use 8 gb of ram which is more then enough and if you are a gmaer 16 gb of ram or above is recommended . The whole thing is that RAM holds up the program which you open on computers . for example :- if you open MS-office then it will open in RAM and it will hold the data till it the program Is opened in the operating system . now if you open MS-paint then the data of ms paint will get open in ram and stored in it and now if you close the ms word some of the files in ram will get deleted but some of it will remain for quickly starting the program i.e ms word here and when you will switch of the main system every data stored on ram will get deleted . there fore its better to save your file before shutting down pc  cause that data get stored in hard disc

What is the difference between SDRAM,DDR2,DDR3,DDR4

The main difference is the speed and voltage used by ram . this is like the generation of ram the more is the number the better is the ram as it will speed up your speed of opening of program (speed also depends on processor) and will lower the electricity bill as it take less voltage as we go to the new technology of RAM.
