Asynchronous transmission Asynchronous data transmission is one of the three methods of data transmission. In asynchronous data transmission, sender or
Data transmission speed is the rate of transferring data from source to destination. It is also referred as Bandwidth. Unit
A network system enables data communication between 2 or more devices. Communication links or channels connects these devices. This link or communication cannel can be of 2 types; point-to-point and multipoint connection. Both of these connections has their advantages and disadvantages and use cases.
Data communication systems enable transfer of data using one of the three transmission modes. Data communication systems has 4 fundamental characteristics; which are delivery, accuracy, timeliness and jitter.
Systems that facilitates this movement of data between devices or end-points are called data communication network. There are 5 components of a data communication network which are data, sender, receiver, transmission medium and protocol.
