For data transmission various methods are used:-
Synchronous Transmission
This method of data transmission involves block of characters that are transmitted at regular time sequences. Each of the block of characters is marked with synchronization characters. The receiving end, accepts the data block, till it detects the ending character or after a predefined number of characters are received, indicating end of a message.
In computer networks, multiplexing is used to refer to a process where multiple channels are combined together to form a single bandwidth, and is transferred across the communication media. As we have cable in t.v. which gives plenty of channels in a single wire. This technique helps in making the transmission more inexpensive by transmitting the expensive signals. The device which perform this task is known as Multiplexer ( MUX ). So, it reveals that the multiplexing is a process of combining many channels in to one single bandwidth.
Data is transferred from the source to the destination in a network. Sometimes the data is transferred in bulk in the network which affects the traffic. Now, if the traffic gets more and more in the network, therefore increasing the congestion. This leads to delay in data receiving or sending packet loss, and blocking of the connection resulting in the capacity of the network.
Network Congestion:- Network protocols are there which help in reducing the network traffic, by taking the SHORTEST PATH ALGORITHM which says that, the data is routed by seeing the shortest path of the desired destination.
Topologies:-is the arrangement of the nodes in a network.There are basic topologies used:
