This article focuses overall on the explanation of what is green computer science and several different ways for you to practice that very same thing. Green computer science is definite as "the study or practice of eco-friendly computing or IT." This type of computing, while growing around the world and being a large part of the overall energy consumption, the problems with that grow as well. With the e-waste that comes with computing, green or otherwise, it is becoming more important than ever to try and find other ways of eco-friendly computing in order to combat the a,punt of e-waste that is produced as a result of the computing. The article highlights 3 different ways of eco-friendly to make sure you are doing your part and it also includes a symbol or brand to look for to make sure that the computer you do use or plan to use is eco-friendly as well. The secondary ways are as follows: 1. Dynamic power scaling which is a technique that allows a drastic reduction in the working rate or frequency of a microprocessor or link interfaces to reduce energy consumption and generation of heat by the chip. 2. Virtualization is a modern IT paradigm which allows separation of technology implementations and computing functions from physical hardware, while cloud computing is virtualization of computer programs via the internet. 3. Using terminal servers is a green computing technique that allows multiple users to connect to a central server, which performs all the processing; however, each user experiences the system on his or her terminal. Finally, the brand or symbol to look for on the computer to make sure that it is eco friendly and consume less power is the Energy Star located on products. In addition, it's not just for laptops; it's for computer monitors, printers, and desktops as well.
