What type of address is used for communication on the internet?

• A. Private address
• B. Local address
• C. Global address
• D. Static address

Answer: (C)

The type of address used for communication on the internet is a global address. Global addresses are part of the Internet Protocol (IP) addressing system, which is essential for routing data across the vast network of the internet. These addresses are unique and publicly routable, allowing devices to communicate with each other over the internet regardless of their geographical locations.

Global addresses ensure that every device connected to the internet can be identified and reached by other devices, facilitating the transmission of data packets. This is crucial for applications such as web browsing, email communication, and online services, where reliable and unique identification of devices is necessary for seamless interactions.

In contrast, private addresses are used within local networks and are not routable on the internet. Local addresses typically refer to addresses used within a specific local area network (LAN) and are not sufficient for global communication. Static addresses refer to fixed addresses assigned to a device, but they can be either global or private depending on the network configuration. Thus, a global address is specifically designed for internet communication, making it the correct choice in this context.
