CDMA vs TDMA
During this discussion I will use the generic term 'CDMA' to refer to the IS-95 standard.
Technically speaking, CDMA is only a means to transmit bits of information, while IS-95 is a transmission protocol that employs CDMA.
You may also hear the term 'TDMA' used to refer generically to the IS-136 standard.
Once again, TDMA is only a method of transmitting bits, while IS-136 is a protocol that happens to employ TDMA.
