What networking model was developed by the United States Department of Defense?

• A. ISO Model
• B. TCP/IP Suite
• C. OSI Model
• D. Decentralized Networking Model

Answer: (B)

The TCP/IP Suite is the networking model developed by the United States Department of Defense. Its development originated from efforts to create a robust and fault-tolerant network that could withstand military and governmental needs, especially during the 1970s. It was designed to facilitate communication across various types of networks and provided a practical framework for the interconnected systems we use today. This model is significant because it encompasses protocols that govern data transmission over the Internet, including the Transmission Control Protocol (TCP) and the Internet Protocol (IP). Together, these protocols form the foundational communication methods that support diverse applications and services on the internet. The incorrect options include the ISO Model and OSI Model, which are theoretical frameworks for networking developed by the International Organization for Standardization. Although very influential, they were not created by the Department of Defense. The Decentralized Networking Model, while a concept within networking, is not a recognized standard or model associated with a formal organization, making it an inappropriate choice in this context.
