Data Communication in Simple Terms Communication means sharing information, it can be local or distant. The definition of telecommunication means communicating at a distance. Data Communication is the exchange of data between devices via some form of transmission medium, for example wire cable. The potency of Information Communication system depends on three essential features:. Delivery: The message sent by the source System is accurately delivering to the right destination is called Delivery. Accuracy: The system ought to deliver the message correctly on the destination System, should any information transmitting to one system to another gets altered or changed and the same uncorrected bits are received on the destination system effects in no use to read the message.

Timeliness: The message must deliver the data in a timely manner. Data transmitted and delivered late to the address systems are worthless.

The five network components that Data Communication deals with are: Message: The message is data or the information to be transmitted or communicated form source system to the address system. This message is in the form of an image, audio, text, or a combination of these. Sender: The sender is the source system or device which sends the message. It could be a computer, phone, work station etc. Receiver: The receiver is the destination system or device that gets the message from source system or sender device. It can be a computer, workstation, phone etc. Medium: A transmission medium is a physical route where a message travels from sender device to the receiver device or from source system to the destination system. Protocol: A protocol is set of regulations and rules that regulate the data communication. It represents a link establishment which will convey between the source systems and the destination system. The connection between the sender and receiver devices or source and destination source might not be established without this protocol. In communicating, presentation of information might be in graphics, text, video, and images audio. The text is represented as bit patterns, a sequence of bits. Distinct sets of bits patterns are designed to represent text symbols. The standards this data representation follows include: ASCII: The American-National-Standards-Institute (ANSI) developed a code called American-Standard-Code-for-Information-Interchange (ASCII). This code uses 7-bits for every symbol to represent it. Extended ASCII: This really is just like the ASCII but chooses 1bit more than ASCII code to create size of each pattern 1 byte (8- bits). This Extended ASCII adds zero to form a pattern of 1 byte, for example, 01111111. UNICODE: This Unicode was developed to understand a variety of languages, since before developed codes only comprehended English. A coalition of software and hardware design is called Unicode. This will represent up to 65536 symbols and is 16-bits. ISO: This is the International Standardization Organization; they developed a code using a 32 bit pattern. Numbers & Images also use bit patterns, an image is divided into matrix of pixels.
