This is the definition of RAM along with its functions and types
When buying a laptop or smartphone, of course you will start looking for the specifications of the item. Well, one of the elements in these specifications is RAM. So, what exactly is RAM?
Well, you are lucky to see this article on Dafunda Tekno. You can read this article to understand what RAM actually means.
What is meant by RAM?
RAM (Random Access Memory) is a device in a computer (PC/Laptop) or smartphone whose function is to store data or temporary program instructions on a device.
So, programs running on laptop/smartphone devices will be temporarily stored in RAM. RAM helps the performance of the processor (computer/smartphone brain).
The speed of processing data on a computer/smartphone depends on the quality of the RAM and processor. So, if you guys are playing this game. So, programs running on your smartphone/laptop are temporarily stored in RAM. So, usually RAM also has an effect on whether or not a smartphone lags in playing a game.
Well, actually RAM has 2 main functions which will be explained below.
What is the function of RAM for?
The data saved after executing a program on the device will be stored permanently on the Hard Disk. However, the problem is Hard Disk usually stores data very slowly.
Therefore, a computer/smartphone requires RAM. RAM speed is very much fast with Hard Disk even with SSD (Solid-State Driver) which is the fastest type of Hard Disk today.
The ability of RAM that is able to read data and store temporary data quickly makes it easier for laptops/smartphones to use many programs/applications or the term multi-tasking.
Now, after the temporary data is moved to the Hard Disk, the data in RAM will be empty. Usually RAM will stop working when the Laptop/Smartphone is turned off.
What kind of RAM is there?
RAM itself has many types and sizes. So, this RAM has a type of size that is usually in the form of 512 MB, 1 GB, 2 GB, 3GB, 4 GB, 8 GB, 16 GB, up to 32GB. Well, for laptops at this time normally already use 4GB and if you want better, use 8 GB. Meanwhile, the latest smartphones are currently using 4 GB of RAM. Even though RAM below 4GB is still “worth it” it is used in 2022.
If you have discussed the size of RAM, now we will also discuss the type of RAM. There are at least 4 types of RAM that you should know, namely:
- EDO RAM (Enhanced Data Output RAM): usually used on older computers to retrieve and store data simultaneously.
- RD RAM (Rambus Dynamic RAM): mostly used in computers from 1999 to the 2000s. RD RAM Has a faster performance when compared to EDO RAM.
- SD RAM (Synchronous Dynamic RAM): Has a high level of synchronization.
- DDR (Double Data Rate): Most commonly found today because the speed is twice as fast as SD RAM, from 133 MHz, 233MHz, to 400MHz. DDR has several generations, ranging from DDR2, DDR3, DDR4, to DDR5.
Laptops now usually use DDR type RAM. Well, that’s a discussion about RAM. If there is something that needs to be discussed, you can write a comment below. Insya Allah will reply as soon as possible.
