What is PSTN,ISDN,CDMA,GSM??
What are their Differences?

PSTN - Public switched telephone network

ISDN - Integrated services digital network

CDMA - Code Division multiple access

GSM - Global system for mobile communication

Did you even bother to Google these terms? They are all on the internet.

I am not going to tell you the differences, look them up on your own.
