System Memory or Random Access Memory (RAM) is a temporary memory used by the central processing unit (CPU) to store information that the operating system (OS) and software applications actively use for faster reading and writing.
When a system doesn't have enough RAM or memory, it will use a slower SSD or traditional hard disk drive that makes the system run slower.
So the more RAM your Samsung Galaxy Book2 Business has, the more tasks it can handle simultaneously, resulting in more responsive and faster performance.
The Samsung Galaxy Book2 Business has two RAM slots which you can use to add or replace with a larger one if it isn't already at the maximum size that the system chipset support. Samsung claims that the Samsung Galaxy Book2 Business supports up to 64GB memory. Here are the memory configurations on Samsung Galaxy Book2 Business.
