Data Flow (Transmission of data):
Data Flow is the way of transmitting data from a device to another. From the Starting of the era of computer science, people want to transfer data. From the effort people give to transfer data this essential topic arises, the data flow the primary sight of data flow from a device to another there are few categories of transmitting data
there are three procedures of transferring data from a device to another, such as
1. Simplex
2. Half-Duplex
3. Full-Duplex
Now I am describing it bellow
Simplex (Simple transmission Method) :
In this kind of transmission, people can send data from one device to another .one device is used to assign data, and another device is used to receive data. The tool that can transmit data it can not accept the data .other side the device which is used for receiving can not send data.
Suppose,
there are Two devices one is Device-A, and the other is Device-B. Here, Device -A can Send data, and Device -B can receive data. Here there is no such a situation where the two devices can change their state. Device-A can't accept, and device-B cannot send
Example,
A CPU(Central Processing Unit) and a Monitor .where a CPU can send the data to Monitor, but the Monitor can not submit the data to CUP.
Half-Duplex (Half Transmission Method)
In this kind of transmission medium, two devices can send or receive data but not at a time. They can play the same role but not at a time.
Suppose,
Two devices, such as Device-A and Device-B, here one device can send data or receive data but at a time.
Here Device- A can send data, and Device -B can receive data at a Time. On the other side, Device-B can send the data the Devie-A can only win.
Example
two wireless devices can communicate with each other, but when a device is sending another device can not submit the data as well .when a device is sending, others have to receive.
Full-Duplex(Full Transmision method)
In this kind of transmission medium, two devices can send or receive data at a time .they both can send and receive tools simultaneously.
Spouse,
Two device-A and device-B can send the data simultaneously at a time they don't have to wait for another device .now days it is become trendy people have more data to send and don't wait for another device state (Sending and Receiving)
Example,
we can consider two computers where two devices can send or receive data at a time .they don't have to wait for each other.
From nowadays we can give the position to this transmission procedure
1. Full-Duplex (Full transmission Medium) - Transmision between Two Computer or laptops
2.Half-Duplex(Half Transmission Medium)- Transmission between two wireless Device
3.Simplex(Simple transmission Medium)- Transmission Between Computer and monitor
this is the necessary discussion of data flow. It can be help full for engineering students. Thank You
