Network and Protocols
When two or more computers connect with each other they form a network. Usually all devices in the network are connected to a router.

Network connections are what make intergalactic communications and the Internet possible. The "network layer" sends packets of data back and forth between different networks.
A basic network link is the Ethernet cable and optic fiber cables that you plug into a modem to access the internet. Nowadays, we also have Wi-Fi, which uses non-physical links to send data wirelessly.

Network connections are what make intergalactic communications and the Internet possible. The "network layer" sends packets of data back and forth between different networks.
A network can also include subnetworks or smaller subdivisions of the network.
Subnetworking is how very large networks, such as those provided by galactic internet service providers, are able to manage thousands of IP addresses and connected devices throughout the galaxy.
Internet protocols handle addressing and routing information and retransmission requests. Network protocols also define rules for communicating in a particular networking environment.
You can think of Internet protocols as traffic rules that a traveling data needs to follow. Things have to be in a specific format addressed to standard addresses and follow the correct path.
The Internet Protocol (IP) is one of the main protocols used at this layer to help different devices around the globe to find and exchange information with each other along with several other protocols for routing, testing, and encryption.
The fundamental flaw within TCP/IP is in its inherent openness, which consequently results in a lack of privacy.
This openness serves the purpose of identifying that device and its user. Even though the information necessary to connect an IP address to either an individual or even a device is frequently not publicly available.
Armed with the IP address, the date, the time and other information like fingerprint information about the devices third parties can determine who the IP address was assigned at that time.
As identity is used simultaneously as a device's address, hackers can simply mock a valid IP address to gain access to your network, observe and record your habits, steal your data, and do much more.
