Explanation
A device is an object made for a special purpose, usually to help us do something more easily. It can be simple, like a clock or calculator, or modern, like a phone or tablet. Devices often use electricity or technology, but not always (for example, a can opener is also a device). In everyday life, people use many devices to work, learn, cook, or travel. For example, a phone is a communication device, and a microwave is a cooking device. In short, a device is a tool or machine designed to solve a problem.
