NET2030: Network Structures
Students acquire an understanding of network infrastructure and assess the advantages and disadvantages of different types of networks. They also develop knowledge of data transmission principles in a computer network and compare features of different network topologies and transmission methods.
Theory
In a document, slide deck, recording, or using another (approved) media, answer the following in full sentences.
- List at least four historical telecommunications devices, not including the telegraph or the internet.
- How have standards for data transmission changed over time, from Morse code to the American standard code for information interchange (ASCII)?
- Create a time line of specific milestones in the history of computer networking.
- What is one emerging networking technology and its potential impact on global communications?
- Give three examples of resources commonly shared within a network environment.
- Compare and contrast peer-to-peer networks and server-based networks with respect to:
- number of work stations
- relative cost
- security
- administration
- data backup
- Describe and compare the structure, purpose and function of local area networks (LANs), metropolitan area networks (MANs) and wide area networks (WANs).
- What is the difference between digital and analogue signalling? Give an example of each.
- Define each of the following as they relate to data signalling and transmission:
- propagation, modulation and encoding
- baseband and broadband signalling
- transmission speed and bandwidth
- attenuation, reflection and noise
- dispersion, jitter and latency
- data collision
- Describe and illustrate the structure of data packets and frames.
- Convert binary numbers 101 and 11111111 to decimal numbers.
- Convert the hexadecimal numbers 21 and FF to decimal numbers.
Throughout the course you will also be evaluated on your basic competencies such as your ability to:
- communicate
- manage information
- use numbers
- think and solve problems
- demonstrate positive attitudes and behaviours
- be responsible
- be adaptable
- learn continuously
- work safely
- work with others
- participate in projects and tasks
Practice
- Install and use packet-sniffing software, such as Wireshark, to capture and analyze data packets and frames.
- Select an appropriate network topology and architecture, and design a network to address user needs, given a particular set of network requirements.
- For example, assemble a LAN gaming network.
- Create a schematic diagram for the physical layout of your designed network.
