Detailed explanation-1: -Serial transmission : data bits are sent one bit at a time over a single wire. Serial transmission used in networks, phones, keyboard and mouse. Parallel transmission : data bits are sent over multiple wires at the same time. It is faster but only works well over a short distance such as several meters.
Detailed explanation-2: -Serial Transmission: In this type of transmission a single link is used to transmit data bits and only one bit is transferred at a time.
Detailed explanation-3: -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.
Detailed explanation-4: -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. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels.
Detailed explanation-5: -In serial communication, data is transmitted one bit at a time (Figure 4.20a). Thus if an 8-bit word is to be transmitted, the 8 bits are transmitted one at a time in sequence along a cable.
