==Asynchronous and synchronous data transmission==
{{Main|Comparison of synchronous and asynchronous signaling}}

[[Asynchronous serial communication]] uses start and stop bits to signify the beginning and end of transmission.<ref>{{Cite news|url=https://www.techopedia.com/definition/6051/asynchronous-transmission|title=What is Asynchronous Transmission? - Definition from Techopedia|work=Techopedia.com|access-date=2017-12-08|language=en}}</ref> This method of transmission is used when data are sent intermittently as opposed to in a solid stream.

[[Synchronous transmission]] synchronizes transmission speeds at both the receiving and sending end of the transmission using [[clock signal]]s. The clock may be a separate signal or [[Self-clocking signal|embedded in the data]]. A continual stream of data is then sent between the two nodes. Due to there being no start and stop bits, the data transfer rate may be more efficient.
