Answer:
In the passage, the techniques that contribute to green computing are:
1. Virtualization: This technique allows the company to reduce their hardware requirements. By using virtualization, multiple virtual machines can be run on a single physical machine, thereby reducing the need for additional hardware.
2. Grid computing: This technique helps reduce the number of machines required to run a process. Grid computing allows multiple computers to work together on a task, thereby optimizing resource usage and reducing energy consumption.
3. Recycling old systems: Recycling old systems is a more environmentally friendly way of disposing of them. Instead of sending old systems to landfills, the company can recycle their components, reducing electronic waste and promoting sustainability.
4. Autonomic computing: Automated systems, such as those enabled by autonomic computing, are more environmentally friendly. These systems can optimize energy usage and resource allocation, leading to more efficient operations and reduced environmental impact.
Therefore, the correct text in the passage that describes techniques contributing to green computing is: "Virtualization will help the company cut down on their hardware requirements. Grid computing will also help reduce the number of machines required to run a process. Recycling old systems is a more environmentally friendly way of disposing of old systems. Autonomic computing can also benefit green computing since automated systems are more environmentally friendly."
