Computer Network: Types of transmission modes

Agenda

• What is Computer Networking
• 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 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
