What are the essential protocols?
There are several protocols that you can know about on the Internet. But, the two most important protocols in discussions will always be the Transmission Control Protocol (TCP) and the Internet Protocol (IP).
In simple words, these protocols set some rules regarding how the information must pass through the Internet. Other devices must also understand the language of a particular device, letting out some info. Without this protocol, a direct connection is the only option to transmit data.
Each device that is connected to the Internet has an IP address. These IP addresses follow the Internet Protocol, making it easier to find another machine through this massive network. The TCP and the IP protocols make the transmission possible when you send a message to another computer or retrieve information from it. While sending a message, your request first hits the DNS ( Domain Name Servers) in search of the target server. It is the reliability of the DNS to point the message in the right direction. Once the target receives the news, it can send back a response to your computer.
