• When data is sent using parallel data transmission, multiple data bits are transmitted over multiple channels at the same time. This means that data can be sent much faster than using serial transmission methods. In the first parallel interface, the data is sent and received in the correct order. • Flexibility of serial links in communication system design. Serial links offer significant flexibility over parallel. Data-carrying capacity. These advantages.
• In parallel transmission, multiple bits (usually 8 bits or a byte/character) are sent simultaneously on different channels (wires, frequency channels) within the same cable, or radio path, and synchronized to a clock. As a result, there is a speedup in parallel transmission bit rate over serial transmission bit rate. • Data transmission, digital transmission or digital communications is the transfer of data (a digital bit stream or a digitized analog signal) over a point-to-point. • Digital data transmission can occur in two basic modes: serial or parallel.
