Computer Networking: Lecture 1 by Dr. Dina Fawzy

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.

Test your understanding of the first lecture in computer networking by Dr. Dina Fawzy, based on the book 'Computer Networking: A Top Down Approach' by Jim Kurose and Keith Ross. This quiz covers topics from the initial chapters of the book.
