Data Flow:-
-----> Data Flow is the concept of flowing Data in the binary language between connected machines.
it help to see the message or the data sends by the sender sides and also help to see the message to the receiver side.
------>Data flow are having three types, namely:
1)Simplex Data flow
2) Half Duplex Data flow
3) Full Duplex Data flow
1) Simplex Data flow:
____________ A is sender ________________
|____A______| --------------------->|______B________|
----> A sends the message but B only receive the data.
2) Half Duplex Data flow:
______________ A is sender ______________
|_____A_______| -------------------->|______B______|
______________ B is sender ______________
|_____A_______| <--------------------|______B______|
-----> A sends the message and B receive it and At one time and in other B sends A receive message.
3)Full Duplex Data flow:
______________ ______________
|_____A_______| <-------------------->|______B______|
------>A and B sends and receive the massage at same time. No compromise.
