Lisämuistimoduulit, commonly referred to as RAM modules or memory sticks, are essential components in modern computing devices. They are physical hardware modules that provide temporary storage for data and instructions that the computer's central processing unit (CPU) needs to access quickly. This type of memory is known as Random Access Memory (RAM) because the CPU can access any part of it directly without having to process preceding data.

When a computer is powered on, the operating system and active applications are loaded into RAM. This allows for rapid retrieval of information, significantly speeding up performance compared to accessing data from slower storage devices like hard drives or solid-state drives. The amount of RAM a computer has directly influences how many applications can run simultaneously and how smoothly they operate. Insufficient RAM can lead to a noticeable slowdown as the system resorts to using slower storage as virtual memory.

Different types of RAM modules exist, with DDR (Double Data Rate) SDRAM (Synchronous Dynamic Random-Access Memory) being the most prevalent. Generations like DDR3, DDR4, and DDR5 represent advancements in speed, efficiency, and capacity. Compatibility is crucial; a motherboard will only support specific types and speeds of RAM modules. Users can often upgrade their existing RAM by installing additional modules or replacing existing ones with higher-capacity or faster alternatives, provided the motherboard supports the new hardware.
