Can someone explain what is meant by network protocol? Need a clear definition!

So, a network protocol is just a fancy way of saying "rules for talking." Computers need these rules to understand each other.

HTTP is for browsing, TCP is for reliable data transfer, and there are others like FTP for file sharing.

If you’re into tech, try using a packet analyzer like Wireshark. It’ll show you what is meant by network protocol in real-time.
