What are the characteristics of parallel transmission
The editor will share with you what are the characteristics of parallel transmission. I hope you will gain something after reading this article. Let's discuss it together.
Parallel transmission refers to the simultaneous transmission of data in groups on multiple parallel channels. Parallel transmission is characterized by fast transmission speed and simple control mode, but the transmission is unstable and easy to lose data. Parallel transmission is only suitable for short distances and requires high transmission speed.

Parallel transmission refers to the simultaneous transmission of data in groups on multiple parallel channels. It is commonly used to transmit several binary codes that make up a character on several parallel channels at the same time. In addition, a control signal, namely "strobe" pulse, is transmitted after the data signal is sent, which is used to inform the receiving equipment that all bits have been sent, and the signals on each channel can be sampled.
This kind of transmission is relatively simple, for 8-bit microprocessors, 8-bit data are transmitted at the same time. The data processed by the microprocessor itself is parallel processing, so there is no need to change the format of the data. Therefore, the interface circuit to realize this kind of transmission is also relatively simple.
In parallel transmission, one character can be transmitted at a time, and there is no synchronization problem between the transceiver and the sender. And the speed is fast and the control mode is simple. However, parallel transmission requires multiple physical channels. Therefore, parallel transmission is only suitable for short distances and high transmission speed.
After reading this article, I believe you have a certain understanding of "what are the characteristics of parallel transmission". If you want to know more about it, you are welcome to follow the industry information channel. Thank you for reading!
