connect=连接 contact=联系

F.e.: connect to the internet connect with the people - NO but contact with people through the internet also I connect him with the music Please, connect me with the hospital (mean through telephone) The word "contact" is more often used in expressions, like for example "to keep in contact with" It is better to use the word "communicate" if you mean directly with the people.

contact means touch with someone.ex.yesterday i contacted my friends. connect means add/touch something...
