Laptops, also known as notebook computers, are portable personal computers designed for mobile computing and compactness. They combine the essential components of a desktop computer, such as a display, keyboard, trackpad or pointing device, processor, memory, and storage, into a single, compact unit. Laptops have built-in rechargeable batteries, allowing users to operate them without a power source for a certain period. They have become popular due to their versatility, portability, and the ability to perform various tasks, such as web browsing, document editing, media consumption, gaming, and more, while on-the-go.
