Final answer:
Adaptive Design refers to the method of creating distinct layouts tailored to different types of devices such as phones, tablets, laptops, and desktops.
Step-by-step explanation:
Designing multiple pages specifically for each type of major device, such as phones, tablets, laptops, and desktops, is known as Adaptive Design. This design approach detects the device that a visitor is using and delivers a pre-set layout for that specific device. For example, a website might have a three-column layout for desktop viewers, a two-column layout for tablet users, and a single-column layout for smartphone users. Each layout is distinct and optimized for the screen size and capabilities of its device category.
