LESSON 3; CHAPTER 3

Computer are useful instruments but have sensitive parts. Just like other equipment, they are prone to damages and malfunction. I learned that we should be very careful in using the computer. We should always remember the safety precautions in using it. But it doesn't mean that we should just take care about it only. They may also harm our health if we did not use it properly. Computers emit enough radiation to harm us. It may damage our health also, including eye strain, wrist injury, and pains in the head, shoulder, back, and neck due to prolonged use of computers. I learned the good work habits in using it, proper workstation design and the proper posture while using it. I learned that we should use the computer properly to avoid damage and malfunction of the computer and of course to avoid accidents that may harm us.
