Computer Network : Transmission Modes

Agenda

1. What is Computer Networking
2. Types of Transmission Modes in Computer Networks

Computer Networking

• It is an interconnected computing device that can exchange data and share resources with each other. 

• These networked devices use a system of rules, called communications protocols, to transmit information over physical or wireless technologies.

Types of Transmission Modes in Computer networks 

There are three types of Transmission modes in computer networks:

Simplex Mode:

• This is unidirectional.

• Sender can only send the data and re can only receive the data.

• Direction of message transmission: sender to receiver.

Examples -

• Mouse/keyboard/joystick to the computer
• Fire alarm system
• Loudspeaker

Half Duplex Mode:

• Both communication points communicate to each other or we can say the sender can send the message to receiver and vice versa but not at the same time.

• This means that while one device is sending, the other device can only receive, and vice versa.

Examples -

• A walkie-talkie
• A two-way radio that has a push-to-talk button
• Browsing the internet (requests, responses)
• Universal Serial Bus (USB)

Full Duplex Mode:

• It is approx the same as Half duplex mode.

• The only difference is that-Sender can send the message and the receiver  can receive the message and vice versa at the same time

Examples -

• Video calls/video conferencing
• Audio calls
• Live chats
