Written Assignment 1
What is the most important difference between a computer and a calculator?
• A calculator is a computer with specific program or set of instruction for mathematical calculations
• A computer is equipment that is centralized around the CPU, microprocessor running specific instruction or application. Calculator is a program or app that can run on a computer
• So the most important difference is the set of instruction that each is designed for. A calculator instruction is specific for mathematical calculation and a computer can accept different programs for several different computation or task.
How are computers today similar to those from World War II? How are they different
• Today computers

• ASCII was initially designed for the English language, and the 256 character limitation struggled to keep pace with the multitude of different languages. Unicode and the support of 100,000 unique character is better suited for the majority of the world language
Why do many PC manufacturers include graphics-processing units (GPUs) in their machines?
• The Graphic Process Unit frees up the CPU for other non-graphic task this allows the GPU to focus exclusively on graphics
Describe several ways you can minimize your negative impact on the environment when you purchase and use a computer.
Proof read your work without printing, this is an easy way to contribute to green environment. Another is to print on both side of your paper. Using the power save feature put your computer in a sleep mode until activated. Screen saver are a absolute no for a green
GPU: GPU stands for Graphics Possessing Unit. It is used for 2D or 3D Graphics, outputting to display monitors,running graphic high intensity applications, etc.This is very mathematically intensive so it takes strain off the CPU.
Home health care is taking care of an individual medically at their residence. Usually, there is a home health aide that comes to the house that provides the medical care for the patient.
3) When you hear the term “making IT eco-friendly”, explain how this is related to Information Technology and the environment.
Describe each of the following properties of the graph of the Cosine Function, f(theta) = cos(theta) and relate the property to the unit circle definition of cosine.
We can reduce air pollution by Conserving energy, Use energy efficient light bulbs, Participate in your local utility’s energy conservation programs, Limit driving by carpooling, using public transportation, biking and walking, Combine Shopping trips for fewer trips, Use electric or hand-powered lawn care equipment and mobiles, Be careful not to spill gasoline when filling up your car, Run dishwashers and washing machines only when full, Choose environmentally friendly cleaners and bleaches, Advocate for emission reductions from power plants and more stringent national vehicle emission standards, Decrease construction, Decrease fuel burning, Space heaters: Use them only when someone is awake
A processor is also known as a CPU which stands for central processing unit, is how a computer/laptop functions and this is like the brain of the computer the better the processor is, the faster a computer works
Dalton Public Schools is currently encouraging that all of its schools go paperless and begin to put all of its assignments and grades on a website called Canvas. This would be a remarkable idea to encourage its staff to be environmentally friendly. Normally, I would include students in my previous statement but while the laptops are a step in the good direction, they have their faults in terms of being environmentally friendly. These
You can also drive less, take shorter showers, save paper and lots of other things to help reduce ones carbon footprint. When it comes to traveling take a bike instead of your car or if you 're flying look for nonstop flights, because therefore you will be producing less greenhouse gas emissions compared to connecting flights.
Environment conservation and protection is an issue, which has gained prominence because of deteriorating environmental balance which is threatening the sustainability of life and nature. Nowadays, environment problems have become the big matters. Every tech companies have to take the key roles to solve them including Intel. The company has proclaimed the Climate Savers Computing Initiative. The Initiative’s goal is to reduce global computer CO2 emissions by 54 million tons per year, equivalent to the annual output of 11 million cars or 10-20 coal-fired power plants. This clearly shows that Intel is trying its best to reduce the pollution of the environment.
Wasting energy- as mentioned above excess energy use in one of the major contributing factors to the deterioration of the environment. Using inefficient devices or leaving devices plugged in and turned while not in use wastes energy unnecessarily and therefore creates a higher demand which in turn means that more greenhouses gases and toxic waste is produced by the companies attempting to meet that demand. Paralowie still uses old inefficient energy systems and is not very adept at managing energy usage. Appliances and devices are left plugged in and turned on even when not in use and this wastes valuable energy. Old incandescent lighting is still used and the energy use could be cut back by investing in natural energy sources such as solar panels.
Efficiency is not always the answer. David Owen explains that society is headed in the wrong direction, believing that to be greener we need to make our everyday lives more efficient when in reality we need to change our behavior. We as consumers want to be sustainable and take care of the Earth we live on while ironically expanding our collection of trinkets. Everything we believe in being efficient and green is misrepresented and to save the Earth the truth needs to be heard.
A computer is an electronic device that stores, retrieves, and processes data, and can be programmed with instructions. A computer is composed of hardware and software, and can exist in a variety of sizes and configurations. Hardware is the physical equipment of a computer system, including the central processing unit (CPU), data-storage devices, terminals, printer, etc. Software is a program or set of instructions or rules that control the operation of a computer.
For one thing, simple lifestyle changes can save kilowatts of electricity. One of these involves turning off the lights and electrical appliances when leaving a room. Shutting off computers can save watts – turning them off at night, and having them hibernate during the day if not in use is a good way to save energy
D) Finally, by turning off unused power sources such as tv's and computers, again you will be helping the environment as well as saving money on energy bills.
The first ever computer was invented in the 1820s by Charlse Babbage. However the first electronic digital computer were developed between 1940 and 1945 in the United States and in the United Kingdom. They were gigantic, originally the size of a large room, and also need to be supply a large amount of power source which is equivalent as several hundred modern personal computers. The history of computer hardware covers the developments from simple devices to aid calculation, to mechanical calculators, punched card data processing and on to modern stored program computers. The tools or mechanical tool used to help in calculation are called calculators while the machine operator that help in calculations is called computer. At first the
