History Of Computer
When was the first computer invented?
The first mechanical computer was invented by Charles Babbage in 1822.
Who was the most important History pioneer?
The most important history pioneer in computer was Charles Babbage because he was the first one to introduce a mechanical computer. He invented and developed he Difference Engine (1820's) and the Analytical Engine (late 1830's) but failed to complete it. His idea leads to further development of computers up today. Because of these, he was considered the father of computing.
What was the first Video Game? what year?
Spacewar is considered the first digital game and was first released in February 1962. It was programmed by Steve Russell.
Who invented the world wide web?
Tim Berners-Lee of London, England invented the world wide web.
Who invented the mouse?
The mouse was invented by Douglas Engelbart.
What was the first Programming language?
The first programming language for a computer was Plankalkül. It was developed by Konrad Zuse for the Z3 between 1943 and 1945. However, it was not implemented until 1998.
Who is considered the "Father" of Computing? Computers? Personal Computing?
Charles Babbage was considered the father of computing; Konrad Zuse, the father of the computer developed Z1, Z2, Z3, and Z4; Henry Edward Roberts coined the term "personal computer" and is considered to be the father of the modern personal computers after he released of the Altair 8800 on December 19, 1974.
Why was Alan Turing so important to Computing history?
He proposed a machine called turing machine in 1936 that became the foundation for theories about computing and computers. The machine was a device that printed symbols on paper tape in a manner that emulated a person following a series of logical instructions.

Entrpreneurship
What does an entrepreneur have that other people don’t have?
They take greater risk than other people do and they work on their own rather than working with somebody else.
Do you know anybody with that ambition? Who? What do they do?
Yes, my dad, he owns a business in the Philippines. He inherited the business from my grandfather. We have a store selling fishes and other He usually get stressed because he needs to gain profit

Explain the difference:
| Career | Job | Entrepreneur |
| It is a chosen occupation or profession that is usually a long term. | It is a regular activity in exchange of payment for the work and is usually a short term. | a person who manages a business that takes greater financial risks than what is usual in order to do so in order to make profit. He works with himself rather than with someone else. |
Drones, Humans Greatest Weapons?
The video implies that drones aren't the humans greatest weapons because even the chimpanzee's tool which is a "stick" can knock it down. It's funny how a chimpanzee defeated a human under the control of drones. What more if a human targets a drone using a weapon like missile? The missile will easily destroy it. Drones still lack a feature to be considered as the greatest weapon.
DRONES
If we believe in freedom, democracy and justice, what is your opinion of Drones in war?
For me, drones should not be used in war for several reasons. First of all, war is a man to man conflict. It should not involve technology that could be controlled over a place not in the vicinity of the war. It is real bravery if you offer your own life to protect your country and people. Secondly, drones can harm the residents of the country more than the the war without using drones. With drones, great chances of number of deaths in the entire country is expected. Lastly, world peace would be harder to solve if drones is used as a future weapon since its a long range technology.

What are brominated flame retardants and why are they needed in computers?
Find out all the chemicals used in the making of a computer:
The industry uses many potentially dangerous gases. Gases are found in ion implanters, diffusion furnaces, expitaxial reactors, etc. Gases are also used in quality control to detect flaws in electronic components. According to an industry journalist, many semiconductor diffusion furnaces are "all too likely to explode." So the exposure can be over a long period of time, or from a short blast.

How can St Pats students do something to recognize Earth Day and increase Awareness of E waste?
Brominated flame retardants (BFRs) are organobromide compounds that have an inhibitory effect on the ignition of combustible organic materials. It is needed in computers because computers are the most widely used electronic technology in a long period of time. Using this, computers will have a reduced flammability.
Who is the Greenest Computer Company? a. Dell? b. Apple
Dell is much a greener computer company than Apple.
Solvents
Xylene(xylol, dimethylbenzene) - High fire hazard
Chlorinated Hydrocarbons
Glycols
The chip manufacturing industry is extremely complicated. Here are two of the most common ways workers are being exposed to chemicals.Solvents are widely used in electronics for cleansing, stripping, degreasing, operations, encapsulation, and as solders. These are activities which are defining the work day for many workers in Silicon Valley. Solvents are also the cause of a large portion of workplace hazards and exposure problems in the industry. The following have been chosen because of their frequency in the industry.

How can St Pats students do something to recognize Earth Day and increase Awareness of E waste?
St Pats should have a seminar, symposium, or camps in which they are educated on what is e waste and what should we do aboout it.They should impliment a program in the school to prevent rapid accumulation of e waste. The action should start first in school and they could also help different communities about this.
