RAM stands for Random Access Memory. This means that it temporary stores files or commands to be used quickly. The reason that temporary files and commands are stored on RAM instead of hard drives is because ram is much quicker to access. The reason for this is that RAM is solid state memory, which can be read very quickly by the computer.
The reason RAM is needed in computers is because, without it the computer would ‘forget’ what to do whenever you tell it to do something, for example:
-
Open a File
-
Run an Application
-
Open A Web Page
-
Download a File
-
Play A Video
-
View A Picture
And Much More…
Solid state memory is usually nothing compared to normal hard drives. An average size of ram in a PC is only around 1GB-2GB, but a typical hard drive can hold between 100GB-400GB.
But new solid state hard drives are becoming available in PC’s and laptops, but they are very expensive to buy and buying a PC or laptop with a solid state hard drives raises the price a lot. But solid state drives are very useful and make the computer run incredibly fast.
