How does a serial communication work?

In serial communication, data is sent one bit at a time using one signal line, so in order for the receiving side to accurately receive the data, the sending side must know at what speed it is sending each bit.In RS-232C, synchronous communication and asynchronous communication standards have been defined.

What is a serial cable and how this cable works?

A serial cable is a cable used to transfer information between two devices using a serial communication protocol. The form of connectors depends on the particular serial port used. A cable wired for connecting two DTEs directly is known as a null modem cable.

What is a serial protocol?

A protocol is an agreement between two parties about how the two parties should behave. A communication protocol is a protocol about how two parties should speak to each other. Serial communication protocols assume that bits are transmitted in series down a single channel.

What is RS-232 protocol?

RS232 is a standard protocol used for serial communication, it is used for connecting computer and its peripheral devices to allow serial data exchange between them. As it obtains the voltage for the path used for the data exchange between the devices.

What cable is used for serial communication?

Serial cables are used for the serial transmission of data. They support communication standards such as RS232, RS422, and RS485, as well as Fibre Channel, IEEE 1394 or FireWire® (Apple Computer, Inc.), and universal serial bus (USB).

What is UART vs SPI?

When you are dealing with the nuances of getting things to work in an embedded system, this can be easy to overlook. However, UART is an actual piece of hardware (a microchip) while SPI is a protocol or specification for communication.

Is SPI serial or parallel?

SPI, Serial Peripheral Interface bus, is a synchronous serial data protocol that was developed by Motorola in the 1970s. The protocol was developed to replace parallel buses and provide high speed data transfers over short distances.

How many bits of data are sent in a serial port?

Most serial ports use between five and eight data bits. Binary data is typically transmitted as eight bits. Text-based data is transmitted as either seven bits or eight bits.
