Laptop memory, commonly referred to as RAM (Random Access Memory), is a crucial component that temporarily stores data for quick access by the computer's processor. It allows multiple applications to run simultaneously and improves overall system performance. The more RAM a laptop has, the better it can handle demanding tasks like gaming or video editing. There are different types of RAM, such as DDR4 and DDR5, which vary in speed and efficiency. Upgrading RAM can enhance a laptop's capabilities, making it faster and more responsive. However, it is essential to ensure compatibility with the laptop's motherboard before making any upgrades.
