Onboard may refer to any of the following:
1. Alternatively referred to as integrated, onboard is a term used to describe a hardware component embedded into a circuit board. With a computer, onboard often refers to a device, like a sound card, network card, GPU (graphics processing unit), or WLAN, integrated onto the motherboard. Unlike expansion cards, users cannot remove these components from their computer. However, they can be disabled through software or CMOS setup or are automatically disabled when an expansion card is added to the computer.
Where are the connections for onboard devices?
When it come to computers, onboard device connections are all on the motherboard's back panel. The picture below is an example of a motherboard with onboard audio and the audio jacks on the back panel. In the example, there is no connection for a monitor because the motherboard does not have onboard video.
What is an onboard computer?
An onboard computer is one or more computers that are part of another device. For example, a car can have many different onboard computers that help monitor and control its various electronic features.
Should I use "onboard," "on-board," or "on board" in my writing
When describing a computer or computer component that is part of another circuit board (as explained above), both "onboard" and "on-board" are correct. For example, both "onboard sound card" and "on-board sound card" are correct when describing a sound card that is on the motherboard. However, when describing anything to do with computers, "on board" (with a space) should never be used.
Computer Hope chooses to use "onboard" on all of its pages for the sake of consistency.
3. When referring to a job or new employee, onboarding is the process a company takes to introduce a new person to the company. A company's onboarding process may include granting access, introducing the company's systems, explaining its rules and its culture, and anything else that makes an employee productive.
