Lesson III
USER'S HEALTH RISKS AND PREVENTION
PART II
PC's are said to be 'user-friendly," but this doesn't mean using them does not have health risks. There are many illness that we can gain in using computer. So if we use computer we make sure we do it right.
GWH(Good Working Habits)
- Tap on the keys and mouse buttons gently
- Avoid long, uninterrupted periods of typing. You can stretch your fingers for 20 minutes.
- Avoid starring at the monitor for long periods. You may take a break for 10 minutes.
PWD(Proper Workstation Design)
- Proper posture. comfortable room.
- Use adjustable workstation and an ergonomic computer chair.
- Place the monitor 16-24 inches away, at eye level or slightly at a lower angle.
- Use extendable legs of the keyboard.
- Place mouse where it is easily accessible by your dominant hand.
- Use a a document holder to minimize vertical head movements.
PP(Proper Posture)
- Sit up straight and put the fee flat on the floor. Use a footrest if needed
- Position you lower arms parallel with the floor and level to your keyboard, with the ekbows at our side.
- Keep wrists straight.

Lesson III
PC CARE AND SAFETY PROCEDURES
FOR USERS(PART 1)
How to take care of your PC
1. Computers should be place in dry and cool place with an electric fan or air conditioning.
2. All cables and connectors must be tied together to keep them away from the walkways to avoid accidents.
3. Avoid eating near the computer cause food bits attracts insects can penetrate the hardware. Spilled drinks might cause short circuits.
4. Always use of AVR(automatic voltage regulator) to regulate electricity.
5. Do no tbump or drop computer components as any damage may cause them to malfunction.
6. Avoid clutter around your computer. Use soft cloth in cleaning the external parts.
7. Always scan computer viruses.

COMPUTER HISTORY
Early Start
Computers have been around for quite a few years. Some of your parents were probably around in 1951 when the first computer was bought by a business firm. Computers have changed so rapidly many people can not keep up with changes.
One newspaper tried to relate how the fast changes in computer technology would look to a similar pace in the auto industry:
The First Computing Machines "Computers"
Since ancient times, people have had ways to deal with data and numbers. Early people tied knots in rope and carved marks on clay tablets to keep track of livestock and trade. Some people considered the 5000 year old ABACUS-- a frame with beads strung on wires to be the first true computing aid.
As trade and tax system grew in complexity, people saw that faster, more reliable and exact tools were needed for doing math and keeping records.
In the mid-1600's, Blaise Pascal and his father, who was a tax officer himself, were working on
taxes for the French government in Paris. The two spent hours figuring and refiguring taxes that each citizen owed. Young Blaise decided in 1642 to build an adding and subtraction machine that could aide in such a tedious and time consuming process. The machine Blaise made had a set ofeight gears that worked together much like an odometer keeps track of a car's mileage. His machine encountered many of problems. For one, it was always breaking down. Second, the machine was slow and extremely costly. And third, people were afraid to use the machine thinking it might replace their jobs. Pascal later became famous for math and philosophy, but he is still remember for his role in computer technology. In his honor, there is a computer language named Pascal.
The next big step for computers arrived in the 1830's when Charles Babbage decided to build a machine to help him complete and print mathematical tables. Babbage was a mathematician who taught at Cambridge University in England. He began planning his calculating machine calling it the Analytical Engine. The idea for this machine was amazingly like the computer we know today. It was to read a program from punched cards, figure and store the answers to different problems, and print the answer on paper. Babbage died before he could complete the machine. However because of his remarkable ideas and work, Babbage is know as the Father of Computers.
The next huge step for computers came when Herman Hollerith entered a contest given by the U.S. Census Bureau. The contest was to see who could build a machine that would count and record information faster. Hollerith, a young man working for the Bureau built a machine called the Tabulating Machine that read and sorted data from punched cards. The holes punched in the cards matched each person's answers to questions. For example, married, single, and divorces were answers on the cards. The Tabulator read the punched cards as they passed over tiny brushes. Each time a brush found a hole, it completed an electrical circuit. This caused special counting dials to increase the data for that answer.
Thanks to Hollerith's machine, instead of taking seven and a half years to count the census information it only took three years, even with 13 million more people since the last census. Happy with his success, Hollerith formed the Tabulating Machine Company in 1896. The company later was sold in 1911. And in 1912 his company became the International Business Machines Corporation, better know today as IBM.
The First Electric Powered Computer
What is considered to be the first computer was made in 1944 by Harvard's Professor Howard Aiken. The Mark I computer was very much like the design of Charles Babbage's having mainly mechanical parts, but with some electronic parts. His machine was designed to be programmed to do many computer jobs. This all-purpose machine is what we now know as the PC or personal computer. The Mark I was the first computer financed by IBM and was about 50 feet long and 8 feet tall. It used mechanical switches to open and close its electric circuits. It contained over 500 miles of wire and 750,000 parts.
The First All Electronic Computer
The first all electronic computer was the ENIAC (Electronic Numerical Integrator and Computer). ENIAC was a general purpose digital computer built in 1946 by J. Presper Eckert and John Mauchly. The ENIAC contained over 18,000 vacuum tubes (used instead of the mechanical switches of the Mark I) and was 1000 times faster than the Mark I. In twenty seconds, ENIAC could do a math problem that would have taken 40 hours for one person to finish. The ENIAC was built the time of World War II had as its first job to calculate the feasibility of a design for the hydrogen bomb. The ENIAC was 100 feet long and 10 feet tall.
M ore Modern Computers
A more modern type computer began with John von Neumann's development of software written in binary code. It was von Neumann who began the practice of storing data and instructions in binary code and initiated the use of memory to store data, as well as programs. A computer called the EDVAC (Electronic Discrete Variable Computer) was built using binary code in 1950. Before the EDVAC, computers like the ENIAC could do only one task then they had to be rewired to perform a different task or program. The EDVAC's concept of storing different programs on punched cards instead of rewiring computers led to the computers that we know today.
While the modern computer is far better and faster than the EDVAC of its time, computers of today would not have been possible with the knowledge and work of many great inventors and pioneers.

"Had the automobile developed at a pace (equal) to that of the computer during the past twenty years, today a Rolls Royce would cost less than $3.00, get 3 million miles to the gallon, deliver enough power to drive (the ship) the Queen Elizabeth II, and six of them would fit on the head of a pin!"These changes have occurred so rapidly that many people do not know how our modern computer got its start.
