Students must be able to explain the central role networks play in our interconnected world.[edit]

Networks play a central role in our interconnected world because they allow people and organizations to communicate, exchange information, and share resources. Networks can take many forms, including computer networks, social networks, and transportation networks.

Computer networks allow people to access the internet and communicate with each other through devices such as computers, smartphones, and tablets. These networks also enable people to access a wide range of resources and services, such as email, social media, online banking, and e-commerce.

Social networks allow people to connect with each other and share information and ideas. These networks can be based on personal relationships, shared interests, or professional connections. Social networks can be local, regional, or global in scope, and they can facilitate the exchange of knowledge, resources, and support.

Transportation networks, such as roads, railways, and air travel systems, enable the movement of people and goods from one place to another. These networks are essential for economic development and trade, and they also facilitate social and cultural exchange.

Overall, networks are critical to the functioning of modern society, and they play a central role in how we live, work, and interact with each other.


Students must be able to discuss the requirements of networks by considering them within a given contextual lens.[edit]

There are several requirements that networks must meet in order to function effectively within a given contextual lens. Some of these requirements include:

  1. Connectivity: Networks must be able to connect different devices, systems, or locations in order to facilitate communication and exchange.
  2. Scalability: Networks must be able to accommodate growth and change in order to support the needs of an expanding or evolving user base.
  3. Reliability: Networks must be dependable and able to operate smoothly, even in the face of disruptions or failures.
  4. Security: Networks must be able to protect against unauthorized access or attacks in order to safeguard sensitive information and assets.
  5. Performance: Networks must be able to support the demands of their users in terms of speed, capacity, and other performance-related factors.

The specific requirements of networks can vary depending on the context in which they are used. For example, a network used for critical infrastructure (such as a power grid) may have different requirements than a network used for social networking (such as a platform like Facebook). It is important for network designers and administrators to consider the needs and constraints of their specific context in order to ensure that the network is able to meet its goals and objectives.
