——Text Messaging——
Text messaging, or texting, is the act of composing and sending electronic messages, typically consisting of alphabetic and numeric characters, between two or more users of mobile phones, computers, tablets, or smartphones.
The term originally referred to messages sent using the Short Message Service (SMS). It has grown beyond only text to include multimedia messages (known as MMS) containing digital images, videos, and sound content, as well as ideograms known as emoji (happy faces and other icons).
