osi refers to open system interface model.it was used as a protocol in earlier days of internet when no set protocols were there.anyone could send data in any number form and the reciever had to decode it using the same number form in which it was sent.thus, a decision was taken to follow a set protocol known as tcp.ip.rest is same as above.
