Today I am going to write about data flow in communication.Data Flow in Communiction means how data transfers between devices.
Communication means the transfer or exchange of data between two different devices.In Communication process whenever data transfers it depends on the condition or depends on devices that through which type data will transfer.
Data Flow in communication have the following types:
1.Simplex
1.Simplex:
In simplex data flow only in one direction.Its mean in simplex if two devices are connected only one device will send data the other device will only recieve data it can not send.
In this type channel will use all of its capacity only in sending data.
Example of this type is:Mouse(it can only input data etc)
2.Half duplex:
In this type of data flow,data will flow in both directions but not at the same time.For example:If two devices are connected both of them can send information to each other but not at the same time.When one device will send data the other will recieve it cannot send back at the same time after recieving it can send data.
In half duplex channel will use all of its capacity for each direction.So this type will be used in the communication in which there is no need of response at the same time.Example of this type is Walkie Talkies.
3.Full Duplex:
In Full Duplex data will flow in both directions at the same time.For Example: If two devices are connected in communication both of them can send and recieve data at the same time.
In Full Duplex channel will divide all of its capacity in both directions.Full Duplex is used when communication is required in both directions at the same time.Example of Full Duplex is calling on mobile phone etc.
