What is TCP/IP?

TCP/IP, or Transmission Control Protocol/Internet Protocol, is like the secret language of the internet.

It's the set of rules that allows devices all around the world to talk to each other and share information.

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.

How does it work?

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.

Connecting two computers, both of which may use different hardware and run different software, is one of the main challenges that the creators of the Internet had to solve.

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.

TCP is the most used protocol, however, you can find other protocols being used over the galactic internet.

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.

It was founded by the Masters of the Order of Epoch who survived the Battle for Earth. Each of the founding Masters specialized in their own branch of skills and powers. - Journals of Order of Epoch, 2324 Anno Domini
Master Talia is the wisest among the Masters. None in the galaxy has more wisdom than her with regard to medicine and cyborg anatomy. She is leading the Order of Epochโ€™s R&D team in biotechnologies that focuses on Shadow matter experiments and gene editing. Red was such a proficient candidate that she was lucky enough to be working with Doctor Talia on Shadow Matter experimentations as an assistant. - Journals of Order of Epoch, 2341 Anno Domini
