Difference between CDMA & GSM- These are the two different means of mobile communication being presently used world wide. The basic difference lies in the Multiplexing method used in the airial communication i.e. From Mobile Tower to your mobile and vice verse... CDMA uses Code Division Multiple Assess as the name itself indicates, for example you are in a hall occupied with number of people speaking different language.
You will find that the one language you are knowing will be heard by you and the others will be treated like noise. In the same manner each CDMA mobile communication takes place with a "code" communicating between them and the other end if one is knowing that code then only it can listen to the data being transmitted i.e. The communication is in the coded form.
On the other hand GSM uses Frequency Division Multiplexing in which each user is allocated a particular bandwidth till the communication is taking place. Thanks. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
