Jargon buster
Plain-language definitions for the technical terms used above.
- DC barrel jack
- A round power connector commonly used for low-voltage DC power supplies, often described by its outer and inner diameters such as 5.5 x 2.1 mm. Matching the barrel size and polarity is important so the plug physically fits and powers the device correctly.
