ITPEC FE Subject A October 2025 Question 56
ITPEC FE Subject A October 2025 — Question 56 of 60
Green IT = using technology to reduce environmental impact (CO₂, energy, physical resources).
- •(d) Web conferencing instead of traveling — replaces physical travel (flights, cars), directly cutting CO₂ emissions. This is the textbook Green IT example.
Why not others:
- (a) Powerful in-house data center — consumes large amounts of energy; opposite of Green IT
- (b) Efficient in-house software — improves development productivity, not an environmental initiative
- (c) Desktop PC instead of thin client — desktops use more power; thin clients are the greener option
Key rule: Green IT = IT that replaces high-emission activities (travel, paper, hardware) or reduces energy consumption. When in doubt, pick the option that cuts CO₂ or physical resource use.
