    • 5.5: Providing Resources in a Network
      Networks connect various devices in our homes, offices, schools, etc. Many devices could be simultaneously connected to the same network, such as a printer, a laptop, a smartphone, and an iPad.
    • 5.6: LANs, WANs, and the Internet
      Devices and media are the hardware of the network. The messages being sent and received from one device to another are the software, and LANs and WANs connect the two devices to facilitate sending the message from the sender to the recipient.
    • 5.7: Network Representations
      Abbreviations apply to networks as well as people's names, school names, etc. Network representations are symbols utilized to represent the different hardware and connections that make up a network.
    • 5.8: The Internet, Intranets, and Extranets

However, converged networks are built to convey data among various devices connected to the same network.
    • 5.11: Reliable Network
      Networks aid various applications and services when it comes to the physical infrastructure of the service or application. Underlying network architecture needs to deliver the four fundamental qualities, which are, Quality of Service (QoS), security, fault tolerance, and scalability.
