Landscape Mode refers to a display orientation in which an electronic device, such as a computer monitor or mobile phone screen, is oriented horizontally. This means that the longer dimension of the device's screen is aligned parallel to the ground, and the shorter dimension perpendicular to it. In other words, when you turn your laptop or smartphone sideways so that its width is greater than its height, you are putting it in landscape mode.
This term comes from the traditional painting format called "landscape," which depicts a view of nature with a horizontal orientation. The phrase has been adopted to describe this type of display because it allows for more space horizontally, making it ideal for displaying wide images or documents without having to scroll left and right.
Landscape mode is commonly used in various applications such as browsing the web, reading e-books, viewing photos or videos, and working on documents that require a lot of horizontal space.
