Which content area would focus on computer networking in KOSSA?

The correct choice is the content area that focuses on Information Technology. This area encompasses a wide range of topics related to computers, software, systems, and networks, making it the most appropriate for studying computer networking specifically. Computer networking involves the design, implementation, and management of network systems that enable computers to communicate and share resources. This includes understanding various protocols, network configurations, hardware, and security measures.

The other content areas, such as Healthcare, Human Services, and Manufacturing, primarily deal with their specific fields. Healthcare focuses on medical knowledge and practices, Human Services emphasizes social programs and support services, and Manufacturing revolves around industrial processes and production. None of these areas directly address the technical intricacies and skills associated with computer networking, which is why Information Technology is the clear choice for this subject matter.
