What function does an IP address serve?

• B. Tracks internet browsing history
• C. Imposes security measures on a network
• D. Encrypts data being sent over the internet

Answer: (A)

An IP address serves the essential function of identifying a device on a network. Each device connected to a network, whether it's a computer, smartphone, or server, is assigned a unique IP address that distinguishes it from all other devices. This unique identifier enables devices to send and receive data to and from one another effectively over the internet or within local networks.

The primary role of an IP address is to facilitate communication between devices by providing a specific address that allows data to be routed correctly. For example, when you access a website, your request is sent to the server associated with that website's IP address, which then responds with the requested information.

This identification is critical for the smooth operation of the internet, as it allows for the proper delivery of packets of data, ensuring that the information reaches the correct destination without confusion among multiple users and devices.
