Every data byte, for example, is prefixed with a 0, and one or more 1s are added at the end.Ī gap may exist between two continuous data-frames (bytes). Data bits have a distinct pattern that aids the receiver in identifying the start and end of data bits. It’s called that since timing isn’t important.

Serial transmission can be either asynchronous or synchronous. Serial transmission requires only one communication channel. In serial transmission, bits are sent one after another in a queued manner. Parallel transmission has the advantage of fast speed, but the downside is the cost of wires, which is proportional to the number of bits sent in parallel. A whole group of bits (data frame) is transferred in one go because the data lines are equal to the number of bits in a group or data frame. On all lines, the sender sends all the bits at the same time. Both computers can tell the difference between high and low-order data lines. With the same number of data lines, the sender and receiver are connected in parallel. The binary bits are grouped into fixed-length groups. Binary data in the form of 1s and 0s can be transmitted in two ways: parallel and serial. How data is sent between two computers is determined by the transmission method. In encoding, each approximated value is then converted into binary format. Approximation of the instantaneous analog value is called quantization. The quantization is carried out between the maximum and least amplitude values. Every discrete pattern depicts the analog signal’s amplitude at that particular time. Sampling transforms a continuous analog signal into a discrete form. The sample rate must be at least two times the signal’s maximum frequency, according to the Nyquist Theorem. The rate at which an analog signal is sampled is the most essential factor in sampling. Every T interval, the analog signal is sampled.
