What should i explain about communication device?

Question

i have to present about communication devices in my class next two weeks. i have a lot of info from the internet. but there are too many that i am confused. what should i tell about it? should i explain the difference between the old communication device and new tech or should i just choose one of the new tech and help advertising it to my class?

Answer 1

Trying to present and explain about All communications devices may be a huge undertaking, other than very brief overview of each.

Once you give a brief overview of historical communications methods and devices from past to present, you could then focus on one of the new communication methods and devices that most people still don't really understand very well - such as VoIP.

VoIP, by itself, can be a rather indepth subject...

Answer 2

explain the basics.

old technology = analog communications (indian smoke signal, telegraph, rotary telephone, HF radio, AM/FM radio)

new technology = digital communications (cellphone, internet, satellite)

* both differs in the mode of  transmission of information. but the information itself is purely and ALWAYS analog in nature.
