# One-Hot-Encoding for features!

I have a question about One-Hot-Encoding, something confusing me.:\

I have this sample dataset. My dataset is categorical:

F1 F2 F3 F4 Target
1 Blue 3 Car Yes
4 Red 6 Ship No
3 Pink 3 Cow Yes
9 Black 6 Fish Yes

### question:

Should I use the One-Hot-Encoding for F2 and F4 too?

This is clear for me, that must be used one hot encoding for column Target. But what about the Features?

If the answer is yes why and if the answer is no why?
