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.
Communication Links
- 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.
