It is a cheap and effective form of serial transmission and is particularly suited for low speed connections such as keyboard and mouse.
It allows for a constant and reliable transmission for time-sensitive data, such as real-time video or voice.A process where data is transferred in regular intervals that are timed by a clocking signal.Synchronous and Asynchronous Transmission Modes Standardised rules allow communications between different devices possible.Protocol is a set of standardised rules used for governing communications between devices.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.Latency is the wait time introduced by the signal travelling the geographical distance as well as over the various pieces of communications equipment.Latency is the delay from the start of the transmission to the time the data transmitted arrive at the destination.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).Bandwidth is usually expressed in bits per second (bps).The amount of data that can be transmitted from one point to another in a given time period (usually a second).Since one symbol can have more than one bit, bit rate will be higher than baud rateīit rate = (baud rate) X (number of bits per symbol).For example, using 4 different frequencies, 4 different 2-bit patterns can be encoded with each frequency encoding either 00, 01, 10, or 11 A symbol/signal may encode more than one bit. The number of symbols/signals per second transferred.The number of bits can be transmitted serially per second.Understand the relationship between bit rate and bandwidth.Differentiate between baud rate and bit rate.
