2. Serial communication - Wikipedia

   en.wikipedia.org/wiki/Serial_communication

   Serial communication is used for all long-haul communication and most computer networks, where the cost of cable and synchronization difficulties make parallel communication impractical. Serial computer buses have become more common even at shorter distances, as improved signal integrity and transmission speeds in newer serial technologies have ...

3. Parallel communication - Wikipedia

   en.wikipedia.org/wiki/Parallel_communication

   The basic difference between a parallel and a serial communication channel is the number of electrical conductors used at the physical layer to convey bits. Parallel communication implies more than one such conductor. For example, an 8-bit parallel channel will convey eight bits (or a byte) simultaneously, whereas a serial channel would convey ...

5. Data communication - Wikipedia

   en.wikipedia.org/wiki/Data_communication

   Data communication, including data transmission and data reception, is the transfer of data, transmitted and received over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires , optical fibers , wireless communication using radio spectrum , storage media and computer buses .

6. Universal asynchronous receiver-transmitter - Wikipedia

   en.wikipedia.org/wiki/Universal_asynchronous...

   At the destination, a second UART re-assembles the bits into complete bytes. Each UART contains a shift register, which is the fundamental method of conversion between serial and parallel forms. Serial transmission of digital information (bits) through a single wire or other medium is less costly than parallel transmission through multiple wires.

7. Comparison of synchronous and asynchronous signalling

   en.wikipedia.org/wiki/Comparison_of_synchronous...

   Practically all parallel communications protocols use synchronous transmission. For example, in a computer, address information is transmitted synchronously—the address bits over the address bus, and the read or write strobes of the control bus. Single-wire synchronous signalling

8. Serial port - Wikipedia

   en.wikipedia.org/wiki/Serial_port

   A serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. [1] This is in contrast to a parallel port , which communicates multiple bits simultaneously in parallel .

9. Asynchronous serial communication - Wikipedia

   en.wikipedia.org/wiki/Asynchronous_serial...

   Asynchronous serial communication is a form of serial communication in which the communicating endpoints' interfaces are not continuously synchronized by a common clock signal. Instead of a common synchronization signal, the data stream contains synchronization information in form of start and stop signals, before and after each unit of ...
