Slash

A slash is a symbol which looks like this: "/". It is most commonly used in the following ways:

1. To show choices – meaning literally “and or”; for example "small/medium/large".
2. To show a ratio of things (“miles/day” in traveling would be how many miles you travel per day; it could be spoken as “miles per day;”)
3. To separate the different parts of a collection of electronic documents.

This third use is the most common use of the "/" symbol in computer and it has been used for a long time. It was created as an aid to organizing and finding the various files you might store on a computer.

See, backslash.
