Introduction to Information Networks
Assessment - Tutorial evaluation
Your Task
This assessment is to be completed individually. In this assessment, you are expected to critically analyse a specific topic from the content covered in Weeks 1 to 3. Your task is to develop a comprehensive tutorial that not only educates learners but also promotes critical thinking about the topic.
Assessment Description
This assessment will gauge your depth of understanding and ability to critically evaluate and synthesise key concepts from Weeks 1 to 3. Your tutorial should be presented as a written document that delves into the intricacies of the topic, incorporating advanced insights and promoting deeper thought. You are expected to present content that goes beyond mere description, demonstrating a critical evaluation of the topic in light of current research and developments in the field.
Learning outcome 1: Evaluate the main technologies, models and protocols used in data communications and networking.
Learning outcome 2: Explain the purpose and functionality of layered computer network models.
Assessment Instruction
Your report should be submitted in Word Document or PDF format.
Your written tutorial should:
Begin with a comprehensive introduction to your chosen topic, setting the context and highlighting its significance in the field of data communications and networking.
Engage in a detailed discussion of the topic, ensuring clarity, depth, and critical analysis throughout. This should be complemented by a synthesis of existing literature, research, and developments.
Incorporate real-world examples or scenarios, but also evaluate their significance and implications in the broader context.
Conclude with a comprehensive summary, key takeaways, and potential future developments or implications in the field.
Seamlessly integrate diagrams, charts, or visuals where they add depth and clarity to your narrative. Ensure these visuals are critically analysed in the text.
Ensure that you cite any sources or materials referenced. All citations should adhere to a recognised academic citation style of your choice, but it must be applied consistently throughout your document. KBS recommends using KBS Harvard referencing style.
Introduction to Information Networks
Learning Outcome 1: Evaluate the main technologies, models and protocols used in data communications and networking.
Learning Outcome 2: Explain the purpose and functionality of layered computer network models.
Learning Outcome 3: Identify problems that emerge among the networks that constitute today's internet architecture.
Learning Outcome 4: Recommend and apply solutions for common internet architecture problems.
Subject Description
This subject introduces students to the fundamentals of information, communication, and computer networks. Students will learn how to evaluate content related to internet architecture and associated protocols, inclusive of network layer architectures, addressing and routing. By the end of the subject, students will have also gained knowledge and skills pertaining to electronic data communication, advanced industry practices and the diagnosis and resolution of internet architecture problems.
What are Information Networks?
Information networks connect devices to enable the transfer of data and information between nodes or endpoints.
These networks can be either wired or wireless and can span a broad or limited area.
The ultimate objective of information networks is to provide reliable and efficient communication and data exchange for users.
Protocols and Standards
Protocols are communication rules for devices on a network, while standards ensure compatibility between devices and networks.
Examples of protocols and standards used in information networks include TCP/IP, HTTP, SMTP, and DNS.
Activity
Example: Online shopping illustrates the importance of protocols and standards in information networks. The HTTP or HTTPS protocol is used to communicate between a device and an e-commerce website's server. The SSL or TLS protocol encrypts and secures payment transactions. Without these protocols, payment information could be compromised.
Activity: Identify three protocols and three standards used in everyday tasks like online banking, social media, or online gaming. Explain why each one is important and how it contributes to the smooth and secure operation of these tasks.
Types of Information Networks
An information network connects nodes to transfer and share data.
It has three categories: Local Area Networks (LANs), Wide Area Networks (WANs), and Metropolitan Area Networks (MANs).
Local Area Networks (LANs)
A LAN is a local network using Ethernet for data transmission in limited geographical areas like buildings or campuses.
Wide Area Networks (WANs)
WANs cover large geographical areas and use long-distance communication technologies like satellite, microwave, and leased telephone lines.
Metropolitan Area Networks (MANs)
A MAN is a city or regional network operated by a single entity, such as a corporation or government agency.
Components of Information Networks
Nodes are network-connected devices, including computers, printers, and routers.
Links are the channels that connect nodes and can be wired or wireless.
Servers are specialised nodes providing centralised services, such as file sharing, email, and web hosting.
Activity
Form groups and research LANs, WANs, or MANs. In your groups, research and discuss the following points related to the assigned type of network:
Definition and characteristics
Advantages and disadvantages
Typical use cases
Examples of companies or organisations that use this type of network.
