Data Transmission Mode !
Today we will learn about different modes of data transmission, that is, whenever we input any data, which mode is used to send the data to the destination, we will know through this article today. So without wasting any time let us start –
What is Data Transmission
See friends, Data Transmission means when any digital or analog data is sent through any medium (wire or wireless) to one or more computers, networks, electronic devices and the process of sending is called Data Transmission. Used to be. And through this process, data or signal is sent in point-to-point, point-to-multipoint and multipoint-to-multipoint environment.
Types of Data Transmission mode
Perhaps you have understood what data transmission is. Now we will know the types of Data Transmission mode. See friends, the type of data transmission mode has been divided into three different categories. And there are three more categories –
1.The ways of Direction
2.Synchronous between devices
3.Number of bits traveling at the same time
1.The ways of Direction
When two devices are transferring data from one place to another using one way or path, this classification has been done according to who will use that way or path at that time.
Simplex
What happens in this method is that data is transferred in only one direction. Meaning, one device only sends data and the device at the other end only receives data. Its example is – data transfer between mouse and processor, data transfer between processor and monitor. In this, data is transferred in only one way. Mouse transfers data only to CPU, CPU never transfers data to mouse.
Duplex transmission
There are two parts to this process – one is Half-Duplex and the other is Full-Duplex.
What is half-duplex transmission?
In Simplex we saw that data is being transferred in only one direction, and in Half Duplex it is the opposite, data is being transferred in two directions only. Meaning, in this process both the devices transfer data to each other, but not at the same time. Meaning, when one device is sending data, the other device will only receive the data and will not be able to send the data. The second device will be able to send data only if the first device does not send the data. Its example is – walkie-talkie
What is full-duplex transmission
In this method, two devices can transfer data simultaneously whenever they want, hence this method is called Full Duplex. Its example is – Phone call (Telephone)
2.Synchronous between devices
What is Synchronous Transmission? When data is being transferred from one device to another, all the data bits are placed one after the other and sent to the destination device. There is no concept of start bit and end bit in this. As you see in the image. Its example is – Chat Rooms, Telephonic Conversations, Telephonic Conversations.
Asynchronous Transmission
And what is Asynchronous Transmission? The concept of start bit and end bit comes. Meaning, when data is being transferred from one device to another, when the first 8 bits segment ends, 1 is put behind it, 1 means end or stop. And then when the segment of second 8 bits starts after that, 0 is written in front of it, that 0 means Start. As you see in the image. Its example is – Forums, Email, Letters.
3.Number of bits traveling at the same time
We know 1 bytes = 8 bits. How are those 8 bits being transferred, meaning are those 8 bits being transferred at once or are those 8 bits being transferred one after the other. And this classification has been done accordingly.
Serial Data Transmission
In this method, those 8 bits are transferred one after the other, hence this method is called Serial Data Transmission. And today all devices transmit data using this serial method.
Parallel Data Transmission
And in this method 8 bits are transferred at once. In this parallel communication, data reaches the destination faster as compared to serial communication. But now you will say that if data transfer is faster in parallel communication then why is serial communication being used today by all the devices for data transfer?
Conclusion
I hope, after reading this blog What is Data Transmission, all your confusion has been cleared and you have learned a lot from this blog. But if you feel any information is missing in this blog or you have any question related to it. So please let us know by commenting below. Your suggestions mean a lot to us. And one more thing, if you want information on any topic, which I have not covered till now, then you can tell that topic by commenting below. I will try my best to clear your topic.
