TCP/IP stands for Transmission Control Protocol/Internet Protocol, and it is the basic system that allows computers and other devices to communicate over the internet. It works by breaking data down into small packets, sending them across a network, and then putting them back together once they reach the correct destination. The IP part is responsible for addressing and routing the data to the right device, while TCP makes sure the data is delivered accurately and in the correct order.
The main purpose of TCP/IP is to make sure information can be shared reliably between different devices and networks. It does not matter what type of device or operating system is being used, because TCP/IP allows them to communicate with each other. This is important for everyday activities like browsing the web, sending emails, streaming videos, and using online services. Without TCP/IP, the internet would not work the way it does today.
