Why do networks use protocols to enable communication and resource sharing?

ATo set rules so devices understand each other

BTo increase the physical size of devices

CTo prevent devices from sharing data

DTo make devices work independently without communication

Step-by-Step Solution

Solution:

Step 1: Understand the role of protocols in networks
Protocols are agreed rules that let devices send and receive data correctly.
Step 2: Match protocol purpose to options
To set rules so devices understand each other correctly states protocols set rules for device communication.
