Reference no: EM13341922

This assignment has three major aims: 

1. Help students gain good understanding of all ITECH1002/5002 theoretical and practical material 

2. To encourage students to use summaries to help prepare for invigilated assessments like theory tests, laboratory tests and examinations. 

3. To encourage students to conduct independent investigation into networking related topics. 

Engagement with this assignment should help students to prepare for the week 7 theory test and the end of semester examination. 

The assignment requires students to: 

1. Summarize the lecture material of weeks 1-9 

2. Answer questions and carry out investigations relating to the material covered in lectures and labs. 

The material covered in ITECH1002/5002 is practically based and as such students will benefit from putting their theoretical knowledge into practice. To this end all students are advised to make use of the lab computers to experiment with Linux and XP. Keen students may also like to set up VirtualBox with associated virtual images so they have their own copy of the operating systems being studied. The Moodle site has instructions to assist students to set up VirtualBox in a similar way to lab machines.

See your course description for actual submission dates. 

Topic summary requirements 

Each topics summary should meet the following minimum standards: 

A minimum of 3 A4 pages of material (text, screen shots, tables, diagrams etc.) that summarises the topics lecture material. 

Optionally students may add extra material associated with that particular topics content. For instance a student could add content they have discovered through experimentation, or from books or the Internet. Although adding optional material will not attract extra marks on the assignment, it may help you to better understand the course content and therefore lead to a better final grade. 

A wealth of information on all topics we cover is available on the Internet. For instance there is a multitude of Linux tutorials and YouTube videos that cover introductory Linux. Engaging with such material will have positive effects on your understanding of the course material. 

As with all academic reports the material you submit must be your own work and definitely not copied and pasted material from the lecture slides, notes pages or elsewhere. 

Other requirements 

Students are also required to answer questions and carry out practical tasks as detailed in the assignment requirements below. Some tasks may require you to take screen captures for inclusion and discussion in your reports 

Part 1 of the assignment covers the following areas: 

• IP networking 

• Number system 

• File systems 

• Linux 

Part 2 of the assignment covers the following areas: 

• Windows

• Virtualization 

o Describe what virtualization is 

o How virtualization solves many driver issues 

o The differences between the Host operating system (OS) & the Guest OS 

o You may like to look up virtualization on the Internet to discover the different virtualization packages available and other useful information about virtualization. 

• Number Systems 

o Describe the structure of the main number systems we investigated in the lecture/lab, in particular Decimal, Binary, Hexadecimal & Octal.
