Activities[edit | edit source]

  1. Review Wikipedia: Computer network#Geographic scale and Wikipedia: Network topology. Consider the different networks you use on a regular basis, including home, school, work, or mobile / cellular networks. Classify each of the networks according to geographic scale as a PAN, LAN, WLAN, MAN, or WAN. Which topologies are in use on these networks? How does the media selected for these networks influence the topology?
  2. Review Microsoft: What is the Difference Between a Domain, a Workgroup, and a Homegroup. Compare and contrast different methods of sharing and storage between a domain, workgroup, and homegroup.
  3. Establish a peer-to-peer network by sharing a folder and then connect to the shared folder:
  4. Investigate whether your school or organization uses "media nets" for voice or video conferencing, and whether any industrial control systems are in place to manage or monitor utilities such as electricity, heat, air conditioning, water, equipment, facilities access, etc.
