Primary Terminologies
- RS-232: This standard specifies the electrical characteristics for serial communications such as voltage levels, signaling timing and connector pinouts used between two devices connected through their interfaces.
- Baud Rate: It refers to the speed (bits per second) at which information is sent across a link over time intervals in serial communication channel.
- Data Bits: Characters representation in number of bits within each byte while communicating using series channels should be taken into account.
- Stop Bits: Extra bits transmitted after each character to mark the end of a transmission.
- Parity: A technique for verifying data sent electronically.
- Flow Control: Methods used by devices to regulate the flow of data and prevent loss or overflow in buffers.
What is Serial Port?
Serial ports are communication interfaces used for the transfer of data between a computer or a device and external peripherals like printers, scanners, and modems among others. In this article, we are going to discuss every point about Serial Ports.
