What network protocol must be installed on a Windows workstation to browse the Internet using broadband DSL?

1. FTP

2. IP

3. TCP

4. UDP

The correct answer is: IP

To browse the Internet using broadband DSL, the Internet Protocol (IP) is essential. IP is a fundamental networking protocol that governs the way data packets are addressed and routed across networks. It provides the mechanism for sending and receiving messages between devices, making it critical for any form of online communication. When a workstation connects to the Internet, it obtains an IP address, which serves as its identifier within the network. This allows the device to send and receive information across the Internet, facilitating web browsing and other online activities. Without IP, the workstation would not have a framework to transmit or receive data packets, rendering it incapable of accessing the Internet. While TCP (Transmission Control Protocol) also plays a crucial role in Internet communication by ensuring the reliable transmission of data, it works in conjunction with IP within the TCP/IP suite. However, IP is the core protocol needed for addressing and routing, which is essential for basic Internet connectivity. Other options like FTP (File Transfer Protocol) and UDP (User Datagram Protocol) serve specific functions, but they are not required for basic Internet browsing; IP is the fundamental protocol for that purpose.
