double character Hexadecimal is just a byte?

Using Arduino Programming Questions

Hello!

I just need a little clarification. If I were to save a double character hexadecimal into EEPROM using EEPROM put, the hexadecimal would only take up one address, right? I've read that a double character hex ( like FF ) is only one byte, so I don't see any problems with this idea but could be completely wrong. I understand that if my hex was over two characters, like FACE, it would take more than one address. If anyone has any tips about working and/or saving hex values into EEPROM that would be wonderful!

Thank you!

Hexadecimal is one of several human readable representations of a binary number.

Two hexadecimal digits are required to specify all possible values of an 8 bit byte.

Since I should only receive two digit hex numbers, I should be able to save in only one address.
