QUESTIONS [90 MARKS]
QUESTION 1 40 MARKS
GRREN COMPUTING
Green computing is the use of new technologies to reduce the amount of energy used by
computers and to make it more efficient. The energy star program, which was created by
the United States, is the best known example of computing. Green computing researches
new ways to provide energy and also ways to improve existing technologies to become
more energy efficient. They are researching the use of solar power, wind power, water
power, sugar, chemicals and nanotechnology in an attempt to find better energy sources so
that we reduce the amount of resources used and pollutants released when we use
computers and other electronic devices. Green computing also looks for ways to reduce the
resources that are used in the process of making computers and other devices. They can do
this through recycling old systems and using the materials to make newer more efficient
computers and by recycling paper and reducing paper to use to prevent wasting resources
while the computer can do all that.
1.1.1 Using practical examples, describe green computing. List and explain the steps
that you can take to contribute to green computing. (15)
1.1.2 Is video conferencing really a viable green alternative to travel for most
companies (10)
1.1.3 How big of a role do green issues such as energy efficiency, carbon footprint,
garbage, waste, water, space and transit play in the value proposition that you
pitch to prospective customers when they are looking at upgrading their data
centre? (15)
QUESTION 2 20 MARKS
2.1 You are buying a personal computer to use for your studies. What operating system
features are important to you? Using examples, differentiate between any four
operating systems that you know. Which one would you choose and why? (10)
2.2 What is an open source software? Explain the benefits and drawbacks for a business
that uses open-source software. (10)

QUESTION 3 30 MARKS
ACCEPTABLE USE POLICY
Most businesses and institutions provide Wi-Fi and internet access to employees and
students while they are at work or at school. While the intention is for the Internet to be
used for work-related purposes, employees or students often find it easy to become
distracted with other activities on the Internet, such as social media, checking personal
email, or visiting unauthorized websites for entertainment.
These activities can degrade Internet access for others or lead to poor performance, as well
as expose the company or institutions to malware viruses or other risks. Many businesses
and institutions create an Acceptable Use Policy (AUP) that outlines how employees or
students should use the Internet at work or at campuses. It also may outline consequences
for unauthorized Internet use.
You are required to:
3.1 Locate two AUPs, one from the internet (published online) and the second one
should be for your institution (Richfield Graduate Institute of Technology).
Compare the two policies and then create a policy you believe would be fair to you
as a student of RGI. Include guidelines for Internet use during school hours, breaks,
use of smartphones, and restrictions for using social media and unauthorized
websites.
Compile your findings in a report format.
