Question
A Uniform Resource Locator, or URL, is defined for our purposes in this questions as having three parts: a protocol specification, a host name, and a path name. The path name is optional. The protocol specification is a sequence of three or more letters followed by a colon. The host name is a sequence of one or more sequences of letters, numbers or underscores that are separated by a dot The path name, if present, is a sequence of names, where a name is a sequence of one or more letters, numbers, underscores, or dots. All of the names in the path name are separated from the other names in the path name by a slash character. The protocol specification is separated from the host name by two slashes. The host name is separated from the path name, if it is present, by a slash.Explanation / Answer
Consider the following URL:
https://www.chegg.com/homework-help/expertquestion
In the given URL, https is the protocol specification. https stands for "hypertext transfer protocol with security".
www.chegg.com is the host name and
homework-help/expertquestion is the path which allows user to go directly to the section they want to visit.
