MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Resource efficiency means using the Earth’s limited resources in a sustainable manner while minimising impacts on the environment. Resource efficiency includes for example re-manufacturing, repair, maintenance, recycling and eco-design.

Detailed explanation-2: -Many factors determine resource use and productivity, including climate, population density, infrastructure needs, domestic availability of raw materials versus reliance on imports, prevailing fuel in the power generation sector, the rate of economic growth, technological development, and the structure of the economy.

Detailed explanation-3: -The term efficiency can be defined as the ability to achieve an end goal with little to no waste, effort, or energy. Being efficient means you can achieve your results by putting the resources you have in the best way possible. Put simply, something is efficient if nothing is wasted and all processes are optimized.

Detailed explanation-4: -Efficiency is when you do the same things faster or with less waste. For example, you might find a better way to run a project status meeting so it takes 30 minutes on average rather than 45 minutes. Effectiveness is finding a way to improve outcomes, perhaps by doing something very differently.
