Green Computing
Definition - What does
Green Computing mean?
Green computing is the environmentally responsible and eco-friendly use
of computers and their resources. In broader terms, it is also defined
as the study of designing, engineering, manufacturing, using and
disposing of computing devices in a way that reduces their
environmental impact.
Many IT manufacturers and vendors are continuously investing in
designing energy-efficient computing devices, reducing the use of
dangerous materials and encouraging the recyclability of digital
devices. Green computing practices came into prominence in 1992, when
the Environmental Protection Agency (EPA) launched the Energy Star
program.
Green computing is also known as green information technology (green
IT).

Techopedia explains Green Computing
Green computing aims to attain economic viability and improve the way
computing devices are used. Green IT practices include the development
of environmentally sustainable production practices, energy-efficient
computers and improved disposal and recycling procedures.
To promote green computing concepts at all possible levels, the
following four approaches are employed:
Green use: Minimizing the electricity consumption of computers and
their peripheral devices and using them in an eco-friendly manner
Green disposal: Repurposing existing equipment or appropriately
disposing of, or recycling, unwanted electronic equipment
Green design: Designing energy-efficient computers, servers, printers,
projectors and other digital devices
Green manufacturing: Minimizing waste during the manufacturing of
computers and other subsystems to reduce the environmental impact of
these activities
Government regulatory authorities also actively work to promote green
computing concepts by introducing several voluntary programs and
regulations for their enforcement.
Average computer users can employ the following tactics to make their
computing usage more green:
Use the hibernate or sleep mode when away from a computer for extended
periods
Buy energy-efficient notebook computers, instead of desktop computers
Activate the power management features for controlling energy
consumption
Make proper arrangements for safe electronic waste disposal
Turn off computers at the end of each day
Refill printer cartridges, rather than buying new ones
Instead of purchasing a new computer, try refurbishing an existing
device
Example
Calculate Your Energy Usage
CoSN's Energy Usage Calculator provides a quick way to estimate annual kilowatt hours and related computer costs of your infrastructure. This calculator allows you to calculate your current data center and estimate the efficacy of proposed energy saving projects.
Evaluate Purchases and Disposal
When it comes to manufacturing computers, peripherals, and other technology, not all vendors are equal, especially concerning use of toxic components and energy required to fabricate and manufacture. Vendors and specialized recyclers have developed programs for salvaging and safely disposing of old computers, displays, and other technology. Before you finalize your disposal plans, be sure to consider your options!
Proper disposal of computers and other technology starts with the purchase. This is the time to determine whether you should use an independent responsible e-waste provider or whether your vendor/supplier has a disposal program you would like to use. Environmentally friendly disposal is easier if there is minimal toxic content to begin with. The Center for Clean Products and Clean Technologies developed the Electronics Environmental Benefits Calculator (EEBC), which is intended to assist institutional purchasers in quantifying the benefits of environmentally sound management of electronic equipment.

History of Computer
The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage.
He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on.
Generally speaking, computers can be classified into three generations. Each generation lasted for a certain period of
time,and each gave us either a new and improved computer or an improvement to the existing computer.
History of the Internet
The history of the Internet begins with the development of electronic computers in the 1950s. Initial concepts of wide area networking originated in several computer science laboratories in the United States, United Kingdom, and France.[1] The US Department of Defense awarded contracts as early as the 1960s, including for the development of the ARPANET project, directed by Robert Taylor and managed by Lawrence Roberts. The first message was sent over the ARPANET in 1969 from computer science Professor Leonard Kleinrock's laboratory at University of California, Los Angeles (UCLA) to the second network node at Stanford Research Institute (SRI).
