Data transmission is usually done in two ways, Parallel transmission and Serial transmission. Serial transmission are divide into to parts Synchronous communication and Asynchronous communication.

Parallel, Synchronous, Asynchronous communication | Data Transmission
In computer system we are know computer are always read or write data in the form of "Yes" or "No" only. At the time of yes or no it consider as 1 or 0 respectively. Because of using 0 and 1 we are consider the "Binary number system". Here data transmit means transmit the 0's and 1's.
Data transmission or transmitting information is usually done in two ways
 |
| Data Transmission |
- Parallel Transmission
- Serial Transmission
Parallel Transmission
To transmit data from one computer to another computer or one node to another node, we are using "Binary Number", binary number means 0 or 1 . In the parallel data transmission data can be transfer into parallel way. Structure of the parallel transmission is very easy. For n numbers of data we are using n numbers of cabal to transmit data.

| Parallel Transmission |
Advantages
- This is very easy process for transmit data, so there is no need to take any others additional information.
- Because of the simplicity normal person can be understand this process easily.
- The probability of data loss on this system is very low.
Disadvantages
- To work on this system we need n numbers of cabal for n numbers of binary data.
- It consumes a lot of electricity.
- This transmission systems are very expensive according to the serial transmission.
Serial Transmission
In the serial transmission system two nodes or two computers can be transmit data using only one cabal. Because of the uses of one cabal this is less cost expensive.

| Serial Transmission |
Advantages
- Its need only one cabal to transmit data.
- It consumes less electricity than parallel data transmission.
- This networking systems are very cheap according to the parallel transmission.
Disadvantages
- This is little-bit complex process for transmit data.
- The probability of data loss on this system is little-bit high according to the parallel data transmission.
Serial Transmission can be categorized into two parts
- Asynchronous Communication
- Synchronous Communication
Asynchronous Communication
In the case of separate transport, the signal is sent one after the other. In this case we are uses 8 bit character at a time. We are using start bit and stop bit for understanding where the data is start or end. Here it use 0 for start bit and 1 is for stop bit. Data transmission speed is lesser than synchronous communication.
Synchronous Communication
In this system multiple bits are transmit through the form of block. In this system there is no start or stop bit to recognize the character, it have fixed time between two blocks to read the data.Because of the using the block(set of multiple binary bits) it take less time to transmit data than asynchronous communication.
