Environmental Considerations

FOR DISPOSAL OF COMPUTERS

Recycling

Computers use a lot of raw material and therefore a lot of it can be recycled. However this does cost the company a fair bit of money for something that they don't even want, for example the transportation of the waste materials. However, if people recycle their old products, the materials can be used to make other computers which means that none of the products will be wasted and this will help the environment.

Energy/Electricity Usage

The running and usage of computer systems requires a lot of electricity as well as providing appropriate cooling systems which uses a lot of electricity as well. Because of these issues, companies have designed computer systems that use a little electricity as possible to save money and to also help the environment. A couple of the methods are:


Sleep and Hibernation Modes

For most of the day computer systems usually aren't used and don't do anything, lying idle. Therefore, sleep and hibernation modes have been created so that when the computer system hasn't been used for a while it will effectively shut down the computer system.


Virtual Servers

Real, physical servers are so powerful they will complete one action in nanoseconds and won't do anything until data is requested again. Therefore they spend most of their time doing nothing, this is very inefficient and it wastes energy and money. To solve this companies are now using 'Virtual Servers'. These are servers that are 'images' of a complete server and they run as a software program on the physical server. Many virtual servers can run on one physical machine, so the loading is much higher. Many data centres now operate with virtual servers.
