Some of the peripheral modules in microcontrollers used for serial communication include USART, SPI, I2C, and USB. And because of the same reasons, serial communication is used commonly in data transfer between a computer and it’s peripheral devices. Besides, the multiple lines used in parallel mode could increase the expense of the communication process. But for long distance and high-frequency data transfer, the parallel mode has proved unsuitable and in such cases, the serial communication method is used. Since parallel communication is faster than serial communication, the internal connections in a computer are in such a way that the data transmission is made in parallel mode. Since for long distance and high-frequency data transmission, the parallel mode has proved unsuitable and in such cases, the serial communication method is used. Therefore internal connections in a computer are in parallel mode. Parallel communication is faster than serial communication. In the parallel communication mode, data is transmitted as blocks. Devices which make use of serial communication technique transmits data bit by bit. There are two ways in which data is transmitted in a computer system-series and parallel.
