Along with IP, which protocol is considered one of the original protocols of the Internet?

The correct answer is TCP. TCP, or Transmission Control Protocol, is one of the foundational protocols of the Internet protocol suite, alongside IP (Internet Protocol). Together, they provide a reliable communication mechanism over the internet.

TCP is responsible for ensuring that data packets are delivered accurately and in the correct order between devices on a network. It establishes a connection-oriented session between the sender and receiver, enabling features such as error checking, data recovery, and flow control. This reliability is crucial for applications that require certainty that data has been successfully transmitted, such as file transfers and web page loading.

While other protocols, such as UDP (User Datagram Protocol) and ICMP (Internet Control Message Protocol), serve specific functions within the network, they do not provide the same level of reliability and connection-oriented service as TCP. UDP is used for applications where speed is more important than reliability, while ICMP is utilized for diagnostic and control purposes in networking. HTTP (Hypertext Transfer Protocol) operates on top of TCP and is used primarily for transferring web pages but is not one of the original protocols of the Internet in the same foundational sense as TCP or IP.

This makes TCP a pivotal protocol in the functioning of the Internet, establishing it as one of the original and essential
