Random Access Memory(RAM)
RAM stands for Random Access Memory, This is a form of computer data storage, but it’s short-term that means data in the RAM is available as long as the device is on. So the application programs and data which is currently in a use kept in the RAM, so they can be quickly accessed by CPU, When the device is rebooted the OS and other files are reloaded in it, usually from an HDD or SSD.
RAM is the main memory of a computer which is much faster than another type of storage such as a hard disk drive (HDD), solid-state drive (SSD). The capacity of RAM I also measured in Megabytes (MB) and Gigabytes (GB), The speed of ram is measured in Megahertz (MHz) and gigahertz (GHz).
Types of RAM
Nowadays we get a RAM in lots of types. As we all know all RAM is used for the same purposes. here is the type of RAM Which is commonly in use.
- Static RAM (SRAM)
- Dynamic RAM (DRAM)
- Synchronous Dynamic RAM (SDRAM)
- Single Data Rate Synchronous Dynamic RAM (SDR SDRAM)
- Double Data Rate Synchronous Dynamic RAM (DDR SDRAM, DDR2, DDR3, DDR4)
- Graphics Double Data Rate Synchronous Dynamic RAM (GDDR SDRAM, GDDR2, GDDR3, GDDR4, GDDR5)
- Flash Memory
All the above RAM work similarly. The main difference in all of those RAM is speed and size of RAM for more Information about the above type RAM you can search it on Google.

How Random Access Memory Works?
Now let’s understand How RAM Work In a simple way, now just assume that your office cabin is your computer, so you have a lot of files in your cabin but you just wanted to work with some of the specific files, now for quick access, you can put that files on your table and easily complect your work.
RAM works same like that, it is very faster than other types of storage devices like hard disk drive (HDD) and solid-state drive (SSD). The files which are currently in use are kept in it, so the processor can quickly reach them to compleat the work, so the speed of your computer is not compactly based on it, it’s also based on the device configuration, I hope you understand how Random-access memory works?
How much Random Access Memory (RAM) we really need?
This is one of the most confusable questions at the time of buying the new device, lots of people say that when we have big RAM we get better speed but it’s not compactly true, the speed on the device is not just based on how much RAM we have, As i already give you the example of office table you can understand that if your office table equal to cabin space you can work at the same speed, So your working speed can’t change with the size of a table,
similarly only more RAM can’t speed up your pc. if you’re a normal user you don’t have lots of heavy work with your devices like photo editing, video editing and graphic designing. you just want a 4 GB of RAM for your work in your computer/laptop in mobile 2 GB to 4 Gb is sufficient for normal work, if you have a heavy work, you can buy more RAM which is sufficient for your work.
Nowadays android application is getting heavy day by day with there update, only one facebook app consume 250 Mb of RAM when it’s in working, so buying a device with a more RAM is good, you can’t upgrade a RAM in mobile, but if you want to upgrade a RAM in computer or laptop you can easily upgrade it, because in a computer it has a specific slot but in the mobile phone, it is connected to the processor, So Before buying anything think that how much RAM you really need because big RAM is Useless.
Is there any difference between a phone’s RAM and a computer’s RAM?
Yes, there is a difference between both RAMS. The computer or laptop have more sockets for holding RAM chips, This allows for easy upgrading and replacement. But the physical size of computer RAM is more as compear to mobile, For technical reasons, phone RAM is normally connected to the motherboard or even on top of the phone’s CPU, Because of that, you can upgrade a RAM in the mobile phone. Another main difference between those RAM is mobile RAM consume less power than computer RAM.
I hope you get all the information about RAM, Types of RAM, How RAM works? and How much RAM we really Need? If you have any question related to RAM please comment Below.
