Hello there,
I wonder whats the difference between these methods ( gets and recv )
loop {
data = current_client.recv(100)
puts data
}
When I use "gets" instead of recv my socket connection stops and never
print out the message?
Why? 
Thanks..

See documentation. #gets tries to read a line (i.e. until it sees a line terminator). Also, I believe recv also works with UDP while I am not sure about gets.
Cheers

Hmm, I looked before at documentation and they wrote...
"A separator of nil reads the entire contents..."
so I did 
@data = gets()
But my code stops after that and wouldn't continue? even though
gets(nil) is the same, I also tried that, didn't work.

in analogy to your recv-Example it should look like:
loop {
data = current_client.gets
puts data
}

Look again. class IO - RDoc Documentation
Note, that instead of gets(nil) you can as well use read.

You need to understand blocking IO: the IO operation blocks until everything is read. In case of a socket, it will only return if there was an error or the other party closed the socket. So, you need to define the protocol in a way that you either know beforehand how much you need to read (then you can use read(length) or recv(length)) or you need a separator that you can use to recognize message end (then you can use gets(separator)).
Kind regards

This doesn't work
I also tried
while(data = gets)
p data
end
The code doesn't continue
