Byte and Bits

Hello!!
I've heard a lot about bytes, which i know what is, an Bits.

So I know there's a difference between Mb and MB (if i understand correct MB is MEGA-BYTE, and Mb is MEGA-BIT.) So what is the difference between BITS and BYTES?

Thanks for all answers, also they who tells me I'm stupid because i don't know it.

thanks.
think i understand more now.
So it is just two different types of data size, like feet and meters?

 

Yep, that simple.

 

Thanks
