What is Protocol: A protocol is a collection of rules that enables electronic devices to interact with one another. These rules specify the data type that may remain communicated, the instructions to send and receive data, and how data transfers are confirmed. A protocol can remain thought of like a spoken language.

What Exactly Is A Network Protocol?
A protocol is a collection of rules for structuring and processing data in networking. Network protocols are similar to a computer language. Although the computers in a network may have quite diverse software and hardware, adopting protocols allows them to interact with one another.
Standardized protocols
Are analogous to a common language that computers may use. In the same way, two humans from different regions may not speak each other’s native languages. Still, they can communicate using a shared third language if one computer and another utilize the Internet Protocol (IP).
They will be able to communicate, much as the United Nations relies on its six official languages to facilitate communication among delegates worldwide. However, if one computer utilizes IP and the other does not, they will be unable to interact.
There are many protocols for different sorts of procedures on the Internet. Protocols remain frequently addressed in terms of the OSI model layer to which they belong.
Which protocols are active at the network layer?
As previously said, IP is a network layer protocol in charge of routing. It is, however, not the sole network layer protocol.
IPsec: Internet Protocol Security (IPsec) establishes encrypted and authenticated IP connections across a virtual private network (VPN). IPsec is not a protocol in and of itself but rather a set of protocols that comprises the Encapsulating Security Protocol (ESP), Authentication Header (AH), and Security Associations (SA).
Internet Control Message Protocol (ICMP):
The Internet Control Message Protocol (ICMP) detects faults and gives status updates. If a router, for example, cannot deliver a packet, it will send an ICMP message back to the originator of the package.
The Internet Group Management Protocol (IGMP) establishes one-to-many network connections. IGMP facilitates multicasting, allowing several computers to receive data packets directed at a single IP address.
What Additional Internet Protocols Are There?
The following are some of the most critical procedures to understand:
TCP: As previously stated, TCP is a transport layer protocol assures consistent data delivery. TCP remains intended to remain used in conjunction with IP, and the two protocols remain frequently referred to as TCP/IP.
The Hypertext Transfer Protocol (HTTP) is the cornerstone of the World Wide Web, the Internet with which most users interact. It remains used for data transport between devices. HTTP is part of the application layer (layer 7) since it converts data into a format that programmes can understand. (For example, a browser) can utilize without additional interpretation. The bottom levels of the OSI model remain handled by the operating system of a computer, not by applications.
HTTPS: The issue with HTTP is that it remain not encrypted, which means that an attacker who intercepts an HTTP message may read it. HTTPS (HTTP Secure) addresses this by encrypting HTTP requests and responses.
TLS/SSL: Transport Layer Security (TLS) is the encryption mechanism used by HTTPS. TLS was previously known as Secure Sockets Layer (SSL).
Conclusion
What exactly is the protocol? It is a collection of rules or processes used in computer science to convey data between electronic devices such as computers. To transmit information between computers, there must first be an agreement on how the information will remain organized and how each side will send and receive it.
