McNemarâs Test is a matched pair test used to determine whether there is a significant change in nominal data before and after an event. We begin with an example. Example 1: In the BBC program The Doha Debates 100 people were surveyed regarding their opinion about capital punishment. 30 were in favor and 70 against.
Name server A name server is a computer server that hosts a network service for providing responses to queries against a directory service. It maps a human-recognizable identifier to a system-internal, often numeric identification or addressing component.
A web server is a computer hosting one or more websites. Hosting means that all the webpages and their supporting files are available on that computer. The web server will send any webpage from the website it is hosting to any user's browser, per user request. Don't confuse websites and web servers. For example, if you hear someone say, My website is not responding, it actually means that the web server is not responding and therefore the website is not available.
