Can you explain what an IP address is and why it is needed in a network?

An IP address is a unique numerical identifier of a device in a computer network, which allows for the unambiguous identification and location of that device.

It is needed for:

• Routing data between devices in the network.
• Ensuring communication and information exchange.

For example, when you visit a website, your computer uses the server's IP address to send a request and receive a response.
