Is two way messaging and text messaging the same thing?

Is two way messaging and text messaging the same thing?
Well the answer is no they are not the same, in fact two way messaging is used in combination with text messaging.
Text messaging is basically the activity of us indulging in sending text messages (SMS - Short Message Service) to another mobile subscriber. For example if you send your friend a message like "C u Later", through your cell phone, you are basically indulging in text messaging.
On the other hand when you send text messages to a short code and they reply back, you are actually getting involved in two way messaging.
An example of two way messaging is consider you see an advertise on television for a poll like "What is you favourite colour ? A-Blue B-Green C-Others, Send your reply POLL A or B or C to 1234."
Here 1234 is the short code to which you have to send your messages to. Consider you send the message "POLL A" to "1234", Most probably they will reply you back with say a message for saying thanks for participating etc. So that's why it is called two way, you send a message and get a reply back.
In normal text messaging on the other hand is just one way, you just send the message, you may or may not get a reply back.
