An IP address is something like a telephone number. It allows another computer with an IP address to send or receive data between the two computers.
Also like a phone number, the IP address can't be duplicated on the same network, each computer needs it's own, and there needs to be a known route between the two.

IP addresses are used to track computers, and to block certain computers from things. Without IP addresses we would not know who is who, also the whole networking would not work.
Computer networking can be defined as the process the establish communication between autonomous systems in a network. Computer networking uses TCP/IP that acts as a guide line or rule book to the computers to know how to talk to other computers.

IP scanners will detect what IP addresses are connected to your computers and what packets are being relayed through and to your personal computers systems.
Computers don't have URLs, they have IP addresses. And yes, you can get someone else's IP address.

what are the similarties between IP and TCP protocol in data communication and networking.
It is the IP address that allows computers to be accessed from other computers. In a way, this is like a name for the computer.
Every computer has MAC address unique to the device. For networking, all computers connect to an IP address, which is initially provided by an ISP. If you have your own router, you can modify your personal IP address to some extent. All pages on the web at their lowest level are an IP address.
