An All-in-One PC, also known as an Integrated PC, is a device that combines the computer's main unit and monitor into a single device. The design concept behind an All-in-One PC is to integrate all the components of a computer into one single device, including the central processing unit (CPU), memory, hard drive, optical drive, display, audio devices, and more. All-in-One PCs typically feature a flat-panel display, with a sleek and compact design that takes up minimal space, making them suitable for placement on office desks or in home environments.
