All-in-One PC

What Does All-in-One PC Mean?

An all-in-one PC (AIO PC) is a computer that has every component within the same case as the monitor, except for peripheral components like the keyboard and mouse. With the advent of LCD monitors, AIO PCs have become much smaller, slimmer and cheaper. Apart from being aesthetically appealing, compact and easy to set up compared to a desktop computer, an AIO PC has reduced power and heat consumption.


An all-in-one PC is also known as an all-in-one desktop.

Techopedia Explains All-in-One PC

Some types of AIO PCs have multi-touch display features. The design is user friendly, and accessories and peripherals can be easily connected. Usually located below or on the side of the monitor, the ports are provided at convenient positions for users. One of the primary advantages of using an AIO PC is that it saves space as the monitor is also integrated into the system. The technology used is similar to that used for manufacturing laptops. This also indirectly brings in another benefit, which is the reduction of cables and, hence, of clutter. An AIO PC does not require a separate video cable or a power cord for the monitor. It is also easier to relocate and is much easier to handle in comparison to a desktop computer. Again, compared to a desktop computer, an AIO PC looks more sleek, consumes less power and generates less heat, and is thus more environmentally friendly.

There are, however, certain disadvantages in using an AIO PC. One of the biggest disadvantages is upgradability. The upgradability is generally limited to RAM upgrades. Customizing, tweaking or self-repairing an AIO PC can be rather difficult. The failure of a single component often results in the need to repair/replace the entire unit. Compared to a desktop computer, an AIO PC has lower graphics capabilities and processing speed. It is also much more expensive than a desktop computer.
