Which protocol is used for communication over the internet?

The Internet is a global network that connects millions of computers and devices.
To ensure smooth communication between these devices, a standard set of rules (protocols) is required.
The most widely used protocol suite is TCP/IP, which is the foundation of all internet communication.
How TCP/IP Works
IP (Internet Protocol): Handles addressing and routing. It ensures that data packets are sent to the correct destination.
TCP (Transmission Control Protocol): Ensures reliable communication by breaking data into packets, sending them, and reassembling them at the destination. It also checks for errors and retransmits lost packets.
Together, TCP/IP makes sure that data travels across networks accurately and efficiently.
Other Protocols Built on TCP/IP
HTTP/HTTPS → Used for web browsing.
FTP → Used for file transfers.
SMTP/IMAP/POP3 → Used for email communication.
VoIP protocols → Used for voice calls over the internet.
So, while many specialized protocols exist, TCP/IP is the fundamental protocol suite that powers communication over the internet.
