Answered on the other one as wel..
A short answer would be that they each allow you to transmit communications.
A longer answer would be that they are all forms of communication which are translated from audio to some form of encrypted transmission, and then back to audio on the other end. Morse gets translated by a person, to morse code, along the line, and back through a person. The sema, tele, and radio are all converted to electrical transmissions which are then translated back in to human form on the other end.

all are forms of communication.
Morse code is a series of beeps sent along a wire or radio waves. Each beep set is a letter which is decoded to spell out a message.
Semaphore is a visual version of Morse Code....same idea, very different signalling.
Telephone....well just about all of us used a telephone
Radio is just like a telephone, but send over the air via radio frequency.
