A developer is designing a system to store configuration codes. A junior programmer suggests that because a 16-bit binary string (such as 1101 1010 1111 0010) can be written as a 4-character hexadecimal string (DAF2), storing the configuration codes in hexadecimal format instead of binary format will reduce the physical storage space needed on the solid-state drive (SSD) by 75%.
Explain why the junior programmer's reasoning is incorrect.
