Step-by-step explanation:
The XO laptop, also known as the One Laptop per Child device, is encased in a plastic cover for several important reasons. Durability is one of the primary considerations; plastic provides a level of shock absorption, which helps to protect the device against drops and impacts. This is essential as the laptop is designed to be used by children around the world, often in challenging environments where ruggedness is crucial.
Another reason for the plastic case is weather resistance. It helps to protect the sensitive electronic components inside from dust, moisture, and other environmental hazards. Furthermore, the lightweight nature of plastic makes the laptop more portable and easier for children to carry.
Last but not least, the plastic cover can be made in bright colors and with a child-friendly design which makes them appealing to children, an important factor considering the target audience of the XO laptop. The design encourages engagement and can symbolize the fun and approachability of learning with technology.
