Summary

Modes of connection refers to the various methods through which devices communicate with each other. 

In computer science, these modes include wired and wireless connections. Wired connections involve physical cables to transfer data, such as Ethernet cables. On the other hand, wireless connections use radio waves for communication, like Wi-Fi and Bluetooth. Devices in a network can be connected in a star network topology, where they directly communicate with a central hub.

To ensure smooth communication, devices use standardised rules known as protocols. These protocols dictate how data is transmitted and received in the form of frames.
