A backward slash is more often referred to as a "whack."
Oblique is also sometimes used to describe a slash.
Internet address example
Below is an example of how a slash may be used when describing a URL (Internet address) to someone over the phone.
https <colon> <slash> <slash> www.computerhope.com <slash> oh.htm is equal to https://www.computerhope.com/oh.htm
