A laptop, also known as a notebook computer, is a device that is designed for mobility and versatility. It is a portable personal computer that typically features a built-in keyboard, touchpad or mouse, and a display screen, all integrated into a single compact unit. Laptops run various operating systems like Windows, macOS, and Linux, and can perform a wide range of tasks, from word processing and web browsing to gaming and graphic design. They come in different configurations, with different processors, memory capacities, and storage options, allowing users to choose a model that best suits their specific needs. Laptops are widely used in both professional and personal settings, offering the flexibility to work or access information from virtually anywhere with an available power source.
