Why do we use Multiple Access Schemes?
because it is necessary to have a scheme that enables
several multiple users to gain access to it and use it
simultaneously.

difference between FDMA, TDMA and CDMA:

TDMA: it is a channel access method for shared medium
networks. It allows several users to share the same
frequency channel by dividing the signal into different
time slots
FDMA: it is used in multiple-access protocols as a
channelization protocol. FDMA gives users an individual
allocation of one or several frequency bands, or channels
CDMA: allowing several transmitters to send information
simultaneously over a single communication channel. This
allows several users to share a band of frequencies
