What does the word "Trident" in my user agent string refer to?

Question

According to the UserAgentString.com website, my user agent string is Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko

Does this mean that I'm using Internet Explorer 11 with an Internet Explorer 7 user agent? UserAgentString.com states that "Trident" is the layout engine for Internet Explorer.

Answer 1

It means that the version of IE is 11 and the version of Trident is 7.

For each IE version since at least IE 8, the Trident version has been the IE version - 4. So IE 8 had Trident/4.0.
