Short messaging systems

The common term for the sending of “short” messages from mobile phones or portable devices is called texting .Texting works using the Short Message Service (SMS).

SMS is a method by which messages can be sent to a cell phone via another cell phone, SMS messages are transmitted within the same cell or to anyone with roaming capability. short messages are not sent directly from sender to recipient, but via an SMS Center. Each mobile telephone network that supports SMS has one or more messaging centers to handle and manage the short messages.

SMS has many advantages as its cheap, reliable, simple, connects many people around the world and is relatively spam free. However only relatively short messages can be sent and as many people rely on their mobile phones constantly, it can be a big distraction. For example texting whilst driving.
