The primary role of RAM, or Random Access Memory, in a computer is to execute instructions and run applications. RAM serves as a temporary storage area where the CPU can easily access data that is actively being used or processed. When you launch a program, the operating system loads it from the hard drive into RAM, because accessing data from RAM is significantly faster than accessing it from a hard drive or SSD. This rapid access allows the CPU to retrieve and execute instructions efficiently, enabling smooth performance and multitasking capabilities.

While RAM does not store data permanently — that function is handled by hard drives or SSDs — its primary purpose is indeed to facilitate quick access to data and support the active processes of the system. Additionally, RAM plays a crucial role in providing a workspace for the operating system and applications, which helps ensure optimal performance during computing tasks.
