NetTalk Beginner's Questions

Hi all,

Using NetSimple object - a 'Client' requesting data from a 'Server'
(as in basic example: Scenario One)

(1) Timing
If a Client has many different things to request from Server,
should it send request 1, wait for response, then send request 2 ?

(2) Also Timing
When Server is working on request 1, it still capable to receive
other requests from other Clients (in background, transparent to
programmer). True ?

(3) Parameters
Can Client send parameters when requesting a command?
eg: Command=1 is to request time
but Server is capable of returning local time of worldwide cities
How can Client ask for time, and City=26 ?

TIA.
