How many bytes?

Could anyone please explain to me why this uses 32 bytes? Shouldn't 8 bits make 1 byte
and this should make up 16 bytes?

Um not 100% sure, but that looks like hex to me. so each individual number would take up 1 byte?

Yup. The chunk of numbers is hexadecimal view from a hex-editor. But each individual number is called a bit. 8 bits make a byte. But I am confused... The book which I took the sample from wrote that this was a 32 bit string. Could someone please help to clarify my doubts?

Hello,

Each hexadecimal digit represents four binary digits also known as bits. So ignoring the equation of 8 bits = 1 bytes, there are 32 bytes as counted. Shown in bold:

Thanks for your help!

Glad I could help!
