TCP/IP, or Transmission Control Protocol/Internet Protocol, is like the secret language of the internet.
Think of it like a giant, interconnected web of information, where every device has its own unique address and can send and receive messages from other devices. TCP/IP is what makes all of this possible, ensuring that your data gets to where it needs to go.
Devices connected between a switch can talk to each other using certain protocols.
In the same way devices in different networks can speak to each other using gateways between networks.
The protocols which are used during this data exchange use the TCP/IP network model. It is a standard that devices follow to have interoperable data transfers.
In networking, a protocol is a standardized way of doing certain actions and formatting data so that two or more devices are able to communicate with and understand each other.
It requires the use of communications techniques that are understandable by all connected computers, just as two people who grew up in different parts of the world may need to speak a common language to understand each other.
This problem is solved with standardized protocols.
One example might be UDP, which is a faster protocol compared to TCP. It is faster yet less reliable, as it does not involve any verification of a connection between the source and the destination. Therefore we see UDP all around applications that require significant amounts of data exchanges such as gaming and video streaming.
Also, it is less secure for DDoS attacks than TCP. As UDP requires no handshake between the source and destination.
