Answer:
B) Communication includes e-mails and voice calls; data transfer includes downloading files and streaming.
Explanation:
Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties. One of the most widely used communication channel or medium is an e-mail (electronic mail).
The linear model of communication comprises of four (4) main components and these are; sender, message, channel and receiver (recipient).
Data transfer can be defined as the transmission of analogue or electronic data such as pictures, music, videos, texts, etc., from one computer node to another computer system through the use of various techniques and technologies.
Communication differs from data transfer in the sense that communication involves the use of channels such as e-mails and voice calls while data transfer includes downloading files and streaming over a Transmission Control Protocol and Internet Protocol (TCP/IP) network, through the use of a file transfer protocol (FTP) on port number 20 or 21.
