When transmitting data via serial communication, what action does the transmitting device perform with the information?

In serial communication, the transmitting device takes the data and converts it into a sequence of bits. This process involves breaking down the information into smaller, manageable units—specifically, bits—before transmitting it over a communication line. Each bit represents a binary value (0 or 1), and these bits are sent one after the other in a serial manner, which is essential for the effective transmission of data, particularly in environments where bandwidth is limited.

This bit-wise transmission ensures that the receiving device can reconstruct the original data accurately by interpreting the sequence of bits it receives, transforming them back into a complete message or signal. This method is a foundational aspect of serial communication protocols.

Other options focus on different processes that may not directly relate to the primary function of a transmitting device in serial communication. For example, combining data into one frame could describe a different type of data packaging, encryption pertains to ensuring data security rather than transmission, and storing data on a disk involves a different context unrelated to transmitting data serially.
