Final answer:
The statement in question is false because e-media refers to methods and platforms of digital communication that rely on electronic technology to transmit information, not to a material substance carrying signals.
Step-by-step explanation:
The statement that e-media is any material substance that carries an electronic signal to support communications between a sending and receiving device is not entirely accurate. Rather, e-media, or electronic media, are forms of communication that rely on electronic technology to transmit information without the need for a physical medium. Examples include the Internet, digital video cameras, cellular telephones, and cable and satellite television and radio. These technologies allow for digital data to be sent as binary codes of ones and zeros, enabling clear transmission, data compression, and a wide range of interactive possibilities such as social media, blogs, podcasts, websites, wikis, instant messaging, and email. Thus, the statement would be false as e-media refers more to the methods and platforms of digital communication, rather than a material substance carrying signals.
