半双工传输模式和全双工传输模式的区别

1. 半双工模式：
半双工模式是发送方可以发送数据，也可以一次接收一个数据。它是双向的，即双向通信，但一次一个。

2.全双工模式：
全双工模式是发送方可以同时发送数据也可以接收数据。它是双向的，即同时双向通信。

半双工传输模式和全双工传输模式的区别：

Sr.No	Half-duplex mode	Full duplex mode
1.	The sender can send as well as receive the data but does one task at a time.	The sender can send as well as receive the data at the same time.
2.	In Half duplex data flow is two-directional but one at a time.	In Full Duplex data flow is two directional and is simultaneous.
3.	Half duplex mode provides less performance than full duplex mode.	Full duplex provides better performance than half duplex mode.
4.	In this there is less utilization of bandwidth during transmission.	In this bandwidth utilization is doubled.
5.	In this, two systems are connected by a point to point link to transmit and receive signal. Both ends can transmit signal but one at a time.	In this, signals are transmitted in both directions; both end stations can receive and send data at the same time. Full duplex mode requires two independent channels for transmission, one for receiving the data and the other for transmitting the data.
6.	Walkie-Talkies and Text message are example of half duplex mode.	Telephone, Instant Chat rooms, Audio Video Calls are example of full duplex mode.
