Backslash: \ (leans backwards)
Forward slash: / (leans forward)

The use of the term “backslash,” in regards to citing a website address, is a commonly accepted error. Website addresses are actually composed of forward slashes. However, backslashes are used in reference to directories and file paths in Windows.

Forward slashes are also known as just “slashes.” In addition to comprising website addresses, forward slashes are used to denote fractions and division. It is also used as a substitute for the word “or.” For example, his/her.
