Objectives: • Define serial and parallel transmission methods and discuss the advantages of serial over parallel transmission. • Define and compare synchronous and asynchronous data transmission. • Describe the purpose of start and stop bits in asynchronous data transmission. Serial and Parallel Data Transmission • electronic data (0s and 1s) can be transmitted by two different methods: • 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.
Buses inside a computer use parallel transmision. Printers are also can be connected via parallel cables within a limited distance. Serial and Parallel Data Transmission Comparision • Serial transmission is cheaper than parallel for two main reasons: • less wires needed • much less complex and size in transmitting and receiving interfaces • Serial transmission is much more reliable over long distance without suffering from 'skew'. 'Skew' can develop in parallel transimission due to slightly different properties in each parallel wire, which could result in different bits travel at different speeds.
• In parallel transmission, a signal transmitted on one wire could create an undesired effect in another wire, resulting in the phenomenon called 'crosstalk'. This isparticularly prominent when using high frequency. • Serial can transmit data at a higher frequency (high bit rate) without suffering 'crosstalk'. Objectives: • Define: • baud rate • bit rate • bandwidth • latency • protocol. • Differentiate between baud rate and bit rate. • Understand the relationship between bit rate and bandwidth. Bit rate • The number of bits can be transmitted serially per second.
EEL201 Term Paper: Serial Communication Over Parallel used for providing better isolation of the channel from the surroundings [13]. Crosstalk Crosstalk creates interference between the parallel lines, and this effect worsens as the length of the communication channel increases.

But the advantage is that cables used with a Serial port are cheaper and narrower.
Baud rate • The number of symbols/signals per second transferred. A symbol/signal may encode more than one bit. For example, using 4 different frequencies, 4 different 2-bit patterns can be encoded with each frequency encoding either 00, 01, 10, or 11 • It is also called symbol rate • Since one symbol can have more than one bit, bit rate will be higher than baud rate bit rate = (baud rate) X (number of bits per symbol) bandwidth • The amount of data that can be transmitted from one point to another in a given time period (usually a second). • Bandwidth is usually expressed in bits per second (bps) • Modern networks typically have speeds measured in the millions of bits per second (megabits per second, or Mbps) or billions of bits per second (gigabits per second, or Gbps). Latency • Latency is the delay from the start of the transmission to the time the data transmitted arrive at the destination. • Latency is the wait time introduced by the signal travelling the geographical distance as well as over the various pieces of communications equipment. • Even fiber optics are limited by more than just the speed of light, as the refractive index of the cable and all repeaters or amplifiers along their length introduce delays.
Protocol • Protocol is a set of standardised rules used for governing communications between devices. • Standardised rules allow communications between different devices possible. • Those rules can include: • speed • data format • error detection and correction • mode of transmission • physical connections, cabling Synchronous and Asynchronous Transmission Modes Synchronous Transmission • A process where data is transferred in regular intervals that are timed by a clocking signal • It allows for a constant and reliable transmission for time-sensitive data, such as real-time video or voice.

• Parallel transmission typically uses synchronous transmission. Asynchronous Transmission • Signals are sent in an agreed pattern of bits and if both ends are agreed on the pattern then communication can take place. • Bits are grouped together and consist of both data and control bits. • If the signal is not synchronised the receiver will not be able to distinguish when the next group of bits will arrive. To overcome this the data is preceded by a start bit, usually binary 0, the byte is then sent and a stop bit or bits are added to the end. • In addition to the control data small gaps are inserted between each chunk to distinguish each group. • Each bit remains timed in the usual way.
