The power of a stationary PC or laptop is calculated by the presence of certain components, including a processor, a video card and RAM. As a rule, the most productive systems are taken for engineering work (3D-modeling, work with video editing, etc.) or demanding games. What is the difference between a laptop RAM and a similar one designed for a PC? How to replace it? What's the price? Which is better - RAM for laptop DDR3 or DDR2? More on this later.
