The history of the Internet began with the development of computers in the 1950s. This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks.
A network gateway is an internetworking system capable of joining together two networks that use different base protocols. A network gateway can be implemented completely in software, completely in hardware, or as a combination of both. Depending on the types of protocols they support, network gateways can operate at any level of the OSI model.Because a network gateway, by definition, appears at the edge of a network, related capabilities like firewalls tend to be integrated with it. On home networks, a broadband router typically serves as the network gateway although ordinary computers can also be configured to perform equivalent functions.
The main theme of dividing the protocol into layers is to explain the rules of each layer specifically. This helps in putting various functions in separate modules and at the same time hiding the details of what they do and how they do it from other layers. This way we could improve the performance of one function or even change it all together, without having to change the whole protocol stack.
For many years there were hundreds of internets: small groups of networks connected to each other within a university, corporation or government agency. It wasn't until widespread acceptance of the TCP/IP protocols that networks from different user communities began to be effectively connected together with compatible data communication structures. Until that point they had to go through a "gateway" that would "translate" the protocols. By definition, an "internet" is merely a connection between computers on two or more networks. Therefore, anybody can build their own two networks and connect them and call it a new "internet".
Routers connect different networks together.
IPv4 and IPv6 are two different protocols . The two protocols are not compatible with each other. But they can exist in a same network together.No, those are two different protocols. However, they can co-exist in the same network (this is known as "dual stack").No, those are two different protocols.

(Apex) Media are connected to networks that make information easier to share and access.
TCP/IP is a "protocol suite", i.e., a group of related protocols, protocols that work together. It is named after two of the most important protocols, TCP and IP - but the TCP/IP stack is made up of many more protocols, it is not just those two.TCP/IP is a "protocol suite", i.e., a group of related protocols, protocols that work together.

This is usually used to describe the Internet. A few computers connected together is a computer network. A few computer networks connected together is a network of networks.
TCP and IP protocols are used for different things. They were developed together and designed to be used together. IP is used for routing purposes. TCP is used for guaranteed reliable delivery (transport). They need each other to get packets from one place to another in a reliable fashion.
There can only be one DHCP server on a network. Two DHCP servers will conflict.
