You are correct, there is a lot more to dive in like NAT, IPv6, static or dynamic address, UPnP, MAC address, subnet space etc.
But I wanted to keep it simple.
DHCP (Dynamic Host Configuration Protocol ) is a communication protocol that is used to coordinate a network via a server. The server in most home cases is your internet router. It coordinates the network.
Think of your network as a town with streets, every street has a unique name aka network address. So when a new device gets into the town it gets a unique address in a certain format, when requested by the clients. Mostly IPv4 i.e. 192.168.178.20.
Second there are ports. Ports are the house numbers of the streets. So if two devices use the same IP they still can be differentiated by using different ports. To address a specific port you write it behind the IP, in our example 192.168.178.20:80. So we use port 80.
To come back to the beginning the router coordinates the IP addresses and the ports from your internal network via DHCP and makes sure every device is accessible and no doubles.
There is a lot more but very briefly this is it.
Check out FHEM, you connect them via MQTT
There is a massive amount of operating systems already. List of operating systems.
Why would you like to create a new one? A lot of the existing systems are specialized for use case and or hardware.
If you want something for general PC use then you have the software problem afterwards, an OS is useless without software support. You need a critical mass of supported software before it takes off. Means money and time.
If you want to make it windows compatible you have the copyright problem, if you are flying to close to the sun it will burn you before you get to your destination .
TL:DR to high effort, low outcome.
