Data transmission also data communication or digital communications is the transfer of data a digital bitstream or a digitized analog signal over a pointtopoint or pointtomultipoint communication. Transmission mode defines the direction of flow of signal between two connected devices. While there are a number of different approaches to this type. Aside from external communication, data transmission may be done internally, between different parts of the same device. In other words, a type of data transmission, which is taken place only in one direction from one. Generally new modes can be tested in the amateur radio service, although national regulations may require disclosure of a new mode. Data representation data representation is defined as the methods used to represent information in computers. In other words, we can say binary one represents a logic high or 5 volts, and zero represents a logic low or 0 volts.
