N
Name Server
A name server translates domain names into IP addresses. This makes it possible for a user to access a website by typing in the domain name instead of the website's actual IP address. For example, when you type in "www.microsoft.com," the request gets sent to Microsoft's name server which returns the IP address of the Microsoft website.
Each domain name must have at least two name servers listed when the domain is registered. These name servers are commonly named ns1.servername.com and ns2.servername.com, where "servername" is the name of the server. The first server listed is the primary server, while the second is used as a backup server if the first server is not responding.
Name servers are a fundamental part of the Domain Name System (DNS). They allow websites to use domain names instead of IP addresses, which would be much harder to remember. In order to find out what a certain domain name's name servers are, you can use a WHOIS lookup tool.

N-Key Rollover
Cybersecurity refers to measures designed to protect your computer, device or network from cybercrime. This involves preventing unintended and unauthorised access, change and damage.
In a basic keyboard, the electrical connections from the base of the keys to the keyboard output (typically a USB connection) may intersect. If you press multiple keys at the same time, the keyboard may register some keystrokes but not others. Ghosting happens when the data from two or more keystrokes gets combined and registers input from a key you did not press.
Most keyboards have some level of rollover, meaning they support multiple simultaneous keystrokes. For example, an inexpensive keyboard might have 5-key rollover, while another might have 8-key rollover. This type of rollover is also called "x-key rollover," where x equals the number of keys that can be pressed and recorded simultaneously.
N-key rollover means there is no limit to how many keys can be pressed and recorded at once. This feature is typically found in high-end keyboards, such as gaming keyboards used in eSports. Gamers often press several keys at once while playing video games, so it is essential for the keyboard to register all the input accurately.
NOTE: The USB interface initially only supported 6 simultaneous keystrokes plus 4 modifier keys. Modern USB interfaces do not have a simultaneous keystroke limit.
