The direction of the data flow can be described as:
1. Simplex
2. Half duplex
3. Full duplex
1. Simplex:- In Simplex data flows in only one direction on the data communication line (medium).
Examples are radio and television broadcasts. They go from the TV station to your home television
2. Half duplex:-In Half-Duplex data flows in both directions but only one direction at a time on the data communication line. For example, a conversation on walkie-talkies is a half-duplex data flow
3. Full-Duplex: In full duplex data flows in both directions simultaneously. Modems are configured to flow data in both directions
The direction of data flow for data transfers are different by these to reasons MP3 files are downloaded from the PC to the MP3 player, in contrast to digital cameras, which transfers or uploads to the PC.

Winds are named for the direction they flow from. For example, a northeast wind comes from the northeast direction.
The address bus is unidirectional(only in one direction) in the processor. So, the flow of information on this bus is from the microprocessor to the attached device(memory module).
The three types of data flow are input data flow, output data flow, and intermediate data flow. An example of input data flow is when user information is inputted into a system, output data flow is when search results are displayed to the user, and intermediate data flow is when data is processed or transformed within the system.

A data flow diagram (DFD) is a graphical representation of the "flow" of data through an information system. DFDs can also be used for the visualization of data processing (structured design).
There are mainly three types of transmission modes : 1) Simplex : Information can flow only in one direction 2) Half Duplex : Information can flow in both direction but only 1 at a time can send and 1 can receive. 3) Full Duplex : Information can flow in both direction and both can send and rceive at a same time.
The main notations for a data flow diagram are - Process - Oval Decision - Rhombus Data Storage - Rectangle Open on the Right Data Flow - Single Arrow Resource Flow - Double Arrow
