What is the primary function of Transmission Control Protocol/Internet Protocol (TCP/IP)?

To establish secure VPN connections
To connect computers to the Internet and enable information exchange
To store and manage data packets
To regulate internal network traffic

The correct answer is: To connect computers to the Internet and enable information exchange

The primary function of Transmission Control Protocol/Internet Protocol (TCP/IP) is to serve as the fundamental suite of communication protocols that enables computers to connect to the Internet and facilitates the exchange of information across different networks. TCP/IP defines how data is to be transmitted over the internet and ensures that it reaches its destination accurately and in the proper order. By breaking down data into packets and addressing each one, TCP/IP allows various types of devices from different manufacturers to communicate with each other, creating a unified and interoperable network. This interoperability is crucial as it enables diverse systems—ranging from servers to personal computers—to interact seamlessly. While aspects such as establishing VPN connections, storing and managing data packets, or regulating internal network traffic can be important in specific contexts, they do not encapsulate the overarching purpose of TCP/IP. Its primary role remains focused on facilitating communication and ensuring that data can be shared across networks, which is vital for the functioning of the Internet as we use it today.
