    Study Notes

    Network Fundamentals

    • Network edge components do not include the network core or intermediate devices.

    Network Devices

    • Smart devices, such as smartphones and laptops, are referred to as devices with a microprocessor.

    Packet Switching

    • Packet switches facilitate the routing of packets between devices on a network.
    • Heterogeneous networks use a combination of copper wire, optical fiber, and radio spectrum for communication.

    Network Performance

    • The transmission rate of a link is measured in bits per second (bps).

    Network Devices

    • Routers forward packets between networks, directing traffic and facilitating communication.

    Non-Traditional Devices

    • Examples of non-traditional computing devices include thermostats, appliances, and other smart devices.

    Network Core

    • The network core mainly consists of packet switches, routers, and other intermediate devices.

    Protocols

    • In the context of networks, protocols refer to standardized rules governing data transmission and communication.

    Lecture References

    • The lecture references a book, with Chapter 1 covering the introduction to computer networks and the internet.

    Lecture Agenda

    • The main focus of the lecture agenda is to introduce computer networks and the internet.

    Network Edge Definition

    • The network edge is defined as the collection of devices that connect to the network, including computers, smartphones, and other endpoints.

    Performance Metrics

    • One of the performance metrics discussed in the lecture is throughput.

    Network Definition

    • The internet is described as 'a network of networks', consisting of interconnected networks.
