allinone

All-in-one (often written all-in-one or allinone) is a term used to describe devices or systems that integrate several previously separate functions into a single unit. The concept is widely used in consumer electronics, computing, printers, and software. In computing hardware, all-in-one PCs consolidate the display and the computer’s motherboard, graphics, and storage into one chassis, reducing desk space and cable clutter. In printing, all-in-one or multifunction printers combine printing with scanning, copying, and sometimes faxing, making them common in homes and small offices. In software and services, some suites are marketed as all-in-one when they bundle multiple tools such as antivirus, backup, data protection, and productivity features into a single package.

Advantages include a compact form factor, simplified setup, and potential cost savings in small-scale deployments. Disadvantages can include limited upgradeability, higher heat or noise density, and the risk that a failure in a shared component disables multiple functions. Some models address this with modular or easily replaceable components, while others remain fully integrated.

The term gained prominence with the rise of multifunction devices in the late 20th and early 21st centuries. Notable contexts include all-in-one PCs from major manufacturers and multifunction printers used in offices and homes.
