In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. Serial transfer refers to transmission of one bit of data at a time from one register to another. Parallel transfer means transmitting of N bits of data simultaneously from one register to another. The transfer of binary bits from one register to another can be done through parallel or serial transfer of data. You cannot increase the signal frequency for a parallel transmission without limit, because, by design, all signals from the transmitter need to arrive at the receiver at the same time.īeside above, what is the difference between serial and parallel transfer what type of register is used in each case? In serial communication a word of eight bits in length is sent sequentially, and is received after all eight bits are sent, one at a time.Īlso Know, why serial communication is faster than parallel? Serial transmission is slower than parallel transmission given the same signal frequency. A parallel communication device sends data in multiple bits to the same direction. The similarity is that both are used to connect and communicate with peripheral devices.Ĭonsequently, what is serial and parallel communication?Ī serial communication device transfers data in bits in the same direction. One of the primary difference is that in Serial Transmission, data is sent bit by bit whereas, in Parallel Transmission a byte (8 bits) or character is sent at a time. Difference Between Serial and Parallel Transmission.
