Networks and the Internet

Standards > Networks and the Internet

Computing devices typically do not operate in isolation. Networks connect computing devices to share information and resources and are an increasingly integral part of computing. Networks and communication systems provide greater connectivity in the computing world.

By the end of grade 2

  • Computer networks can be used to connect individuals to other individuals, places, information, and ideas. The Internet enables individuals to connect with others worldwide.

  • Connecting devices to a network or the Internet provides great benefits, but care must be taken to use authentication measures, such as strong passwords, to protect devices and information from unauthorized access.

By the end of grade 5

  • Computing devices may be connected to other devices to form a system as a way to extend their capabilities.

  • Software and hardware work together as a system to accomplish tasks (e.g., sending, receiving, processing, and storing units of information).

  • Shared features allow for common troubleshooting strategies that can be effective for many systems.

By the end of grade 8

  • The study of human-computer interaction can improve the design of devices and extend the abilities of humans.

  • Software and hardware determine a computing system’s capability to store and process information. The design or selection of a computing system involves multiple considerations and potential trade-offs.

  • Troubleshooting a problem is more effective when knowledge of the specific device along with a systematic process is used to identify the source of a problem.

By the end of grade 12

  • The usability, dependability, security, and accessibility of devices within integrated systems are important considerations in their design as they evolve.

  • A computing system involves interaction among the user, hardware, application software, and system software.

  • Successful troubleshooting of complex problems involves multiple approaches including research, analysis, reflection, interaction with peers, and drawing on past experiences.
