What Is Key Rollover?
To grasp the meaning of full N key rollover, it’s essential first to understand the basic concept of key rollover itself. Key rollover refers to the number of keys that a keyboard can register when pressed simultaneously.
The Basics Of Key Rollover
Most keyboards have limited rollover capabilities. A common type is 2-key rollover (commonly referred to as 2KRO), meaning two keys can be pressed at once and still be registered by the keyboard. If a third key is pressed while the first two are engaged, the keyboard may not recognize that third press.
Key rollover is crucial for gaming, typing, and scenarios where multiple key presses are necessary. Limited key rollover can lead to missed inputs, resulting in frustrating experiences.
What Is Full N Key Rollover?
Full N key rollover (often shortened to full NKRO) refers to a keyboard’s ability to register all keys being pressed simultaneously without any missed inputs. This means whether you’re pressing one key, two keys, or every key on the keyboard, each press will be accurately recorded.
The Terminology Behind Full NKRO
The “N” in full N key rollover indicates that there is no limit to the number of keys pressed simultaneously. Whether it’s ten, twenty, or all keys at once, a keyboard supporting full NKRO will capture each keystroke.
Why Is Full N Key Rollover Important?
Understanding the significance of full N key rollover is vital for both casual users and hardcore gamers. Here are some key reasons why it matters:
