A(n) ______________ is a binary number that uniquely identifies a host computer connected to the Internet.
Correct Answer
D. IP Address
Explanation
An IP address is a binary number that uniquely identifies a host computer connected to the Internet. It serves as a unique identifier for devices on a network, allowing them to communicate with each other. IP addresses consist of a series of four numbers separated by periods, with each number ranging from 0 to 255. This addressing scheme allows for the routing of data packets across the Internet, ensuring that they are delivered to the correct destination.
