The well-known examples of simplex method are Television and Radio. So simplex method is one-way communication technique. So if the sender is transmitting the data then receiver can only accept and vice versa. In simplex method either of the medium i.e sender or receiver can be active at a time.
#Serial communication protocol example full
The transmission modes are classified as Simplex, Half Duplex and Full Duplex.

There are several types of serial communication depending on the type of transmission mode and data transfer. binary pulses and it is well known that, binary one represents the logic HIGH and zero represents the logic LOW. Transmission Modes in Serial CommunicationĪs already said above that in serial communication data is sent in the form of bits i.e. The protocol is the secure and reliable form of communication having a set of rules addressed by the source host (sender) and destination host (receiver) similar to parallel communication. Every electronics device whether it is Personal Computer (PC) or Mobile runs on serial communication. Serial communication is the most widely used approach to transfer information between data processing peripherals. In this article, the different types of Serial Communication Protocols will be discussed. Similarly there are several examples of Serial Communication Protocols such as CAN, ETHERNET, I2C, SPI, RS232, USB, 1-Wire, and SATA etc. Examples of Parallel Communication Protocols are ISA, ATA, SCSI, PCI and IEEE-488. Similarly the protocols are divided into two types such as Serial Communication Protocol and Parallel Communication Protocols. There are different types of data transfer available in the digital electronics such as serial communication and parallel communication. More specifically, the data bits are transmitted one at a time in sequential manner over the data bus or communication channel in Serial Communication. one after the other then the communication protocol is known as Serial Communication Protocol. This exchange of data bits in microcontroller is done by some set of defined rules known as communication protocols.
In embedded systems, the communication means the exchange of data between two microcontrollers in the form of bits. The communication is very well known terminology which involves the exchange of information between two or more mediums. For example, If 011 is a number the parity bit=0, i.e., even parity and the parity=1, i.e., odd parity.īefore starting with Serial Communication Protocols, Let’s break the terminology in three parts. There are of four kinds, i.e., even odd, marked and spaced. Parity Bit is the simplest form of checking the errors. Stop Bits are used for a single packet to stop the transmission which is denoted as “T”. In telephone lines, the baud rates will be 14400, 2880. For example, if the baud rate is 200 then 200 bits per Sec passed. It is described as the number of bits passing in one second. Synchronous Data Transfer – The mode in which the bits of data are synchronized by a clock pulse.īaud rate is used to measure the speed of transmission. Clock pulse is a signal used for synchronization of operation in an electronic system. Modes of Data Transfer in Serial Communication:Īsynchronous Data Transfer – The mode in which the bits of data are not synchronized by a clock pulse. Parallel communication- you are shooting a target using a shotgun, where no. Serial communication – you are shooting a target using machine guns, where bullets reach one by one to the target. So, there is ease of deployment.Protocol is just like a common language that system uses to understand the data. It supports the most widely used protocol, Internet Protocol (IP). It reuses the existing dial-up connections and telephone lines. So, it is suitable for usage in microcontrollers. If this flag is present in the data, then an escape sequence precedes it, so that the receiver does not consider it as the end of the frame.
The flag is generally a special character equivalent to decimal 192. SLIP frame has a very simple format, comprising of payload and a flag that acts as an end delimiter. SLIP was developed by Rick Adams in 1984. The ISP then sends the results back to the client via the SLIP lines. The ISP responds to the request and passes it over to the Internet via high speed multiplexed lines. When a service is required, the client places a request to the ISP. They provide communications between machines that were previously configured for direct communication with each other.įor example, a client may be connected to the Internet service provider (ISP) with a slower SLIP line. Serial Line Internet Protocol (SLIP) is a simple protocol that works with TCP/IP for communication over serial ports and routers.
