Which of the following is not an internet protocol?
In the vast and complex world of the internet, protocols play a crucial role in ensuring that data is transmitted efficiently and securely. However, with so many protocols available, it can be challenging to determine which ones are actually internet protocols and which ones are not. This article aims to shed light on this topic by identifying the protocol that does not belong to the internet protocol suite.
The Internet Protocol Suite, commonly known as TCP/IP, is a set of communication protocols used for the internet and similar networks. It includes several key protocols that work together to enable data transmission across the internet. Some of the most well-known internet protocols are:
1. Internet Protocol (IP): This protocol is responsible for addressing and routing packets of data across the internet. It assigns unique IP addresses to devices and ensures that data is delivered to the correct destination.
2. Transmission Control Protocol (TCP): TCP provides reliable, ordered, and error-checked delivery of a stream of octets between applications running on hosts communicating over an IP network. It breaks data into packets, ensures they are delivered in the correct order, and reassembles them at the destination.
3. User Datagram Protocol (UDP): UDP is a connectionless protocol that allows applications to send datagrams without establishing a connection. It is often used for real-time applications, such as streaming video and voice over IP (VoIP).
4. Hypertext Transfer Protocol (HTTP): HTTP is the protocol used for transmitting web pages and other resources over the internet. It defines how clients (web browsers) and servers communicate and exchange data.
5. Simple Mail Transfer Protocol (SMTP): SMTP is the protocol used for sending and receiving email messages. It ensures that email is delivered to the correct recipient and handles the transmission of messages between mail servers.
Now that we have discussed some of the key internet protocols, let’s move on to the protocol that does not belong to the internet protocol suite.
Protocol that is not an internet protocol
The protocol that does not fit into the internet protocol suite is the Hypertext Transfer Protocol Secure (HTTPS). While HTTPS is closely related to HTTP, it is not an internet protocol itself. Instead, it is a security protocol that builds upon HTTP to provide secure communication over the internet.
HTTPS uses Transport Layer Security (TLS) or Secure Sockets Layer (SSL) to encrypt the data transmitted between the client and server. This encryption ensures that sensitive information, such as login credentials and personal data, is protected from eavesdropping and tampering.
In summary, the internet protocol suite consists of protocols like IP, TCP, UDP, HTTP, and SMTP, which are essential for data transmission and communication over the internet. However, HTTPS, while crucial for securing web traffic, is not an internet protocol itself but rather a security protocol that complements the existing suite.
