Many ICs have serial interfaces, as opposed to parallel ones, so that they have fewer pins and are therefore less expensive.ДЇrom Wikipedia, the free encyclopedia.

In many cases, serial is cheaper to implement than parallel. Several factors allow serial to be clocked at a higher rate. Although a serial link may seem inferior to a parallel one, since it can transmit less data per clock cycle, it is often the case that serial links can be clocked considerably faster than parallel links in order to achieve a higher data rate. A parallel link transmits several streams of data simultaneously along multiple channels e. The communication links, across which computers or parts of computers talk to one another, may be either serial or parallel. In IC, serial bus may be typically implemented by using multiplexer which utilizes technique called multiplexing. To reduce the number of pins in a package, many ICs use a serial bus to transfer data when speed is not important. Integrated circuits are more expensive when they have more pins. Many communication systems were generally designed to connect two integrated circuits on the same printed circuit boardconnected by signal traces on that board rather than external cables. The cables that carry this data other than 'the' serial cable and the computer ports they plug into are usually referred to with a more specific name, to reduce confusion. Practically all long-distance communication transmits data one bit at a time, rather than in parallel, because it reduces the cost of the cable. Many serial communication systems were originally designed to transfer data over relatively large distances through some sort of data cable. Serial computer buses are becoming more common even at shorter distances, as improved signal integrity and transmission speeds in newer serial technologies have begun to outweigh the parallel bus's advantage of simplicity no need for serializer and deserializer, or SerDes and to outstrip its disadvantages clock skewinterconnect density. Serial communication is used for all long-haul communication and most computer networkswhere the cost of cable and synchronization difficulties make parallel communication impractical. This is in contrast to parallel communicationwhere several bits are sent as a whole, on a link with several parallel channels. The parity bit is set to space 0 if the total number of data bits in the mark 1 state is odd.In telecommunication and data transmissionserial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. The parity bit is set to space 0 if the total number of data bits in the mark 1 state is even. Single Ended mode can be used over short runs of up to 15 metres.Дifferential mode can work up to metres. Differential mode uses a pair of wires where the voltage is the difference between the two wires. Single Ended mode uses a single wire where the voltage is measured with respect to ground. There are a number of standards which define the electrical signals that represent a mark 1 bit or a space 0 bit.

Individual bits are represented by electrical signals. Portal vstД¬ommon values used by PLC Devices are 1 or 2 stop bits. The Stop Bits is the number of bits used to mark the end of a frame. If a bit error is detected, the receiver can ignore the corrupted data byte. If the received parity bit does not match the expected parity bit, one or more bits have been corrupted. The receiver calculates the expected parity bit for the received data. When a data byte includes Even or Odd parity, the receiver can detect single bit errors. Common values used by PLC Devices include 7 or 8 data bits. The Data Bits is the number of bits of data in each frame. The Baud Rate is the speed at which data bits are sent. To successfully connect two devices using serial communications, both devices must use the same set of parameters.
