2. AT THE END OF THIS MODULE, YOU SHOULD BE ABLE TO:
1. Determine requirements of task in accordance with required
output
2. Select appropriate hardware and software according to task
3. Plan a task to ensure that OHS guidelines and procedures are
followed
4. Follow client-specific guidelines and procedures
4. THE FOLLOWING ARE SOME FACTORS TO BE CONSIDERED
WHEN YOU PLAN AND PREPARE FOR THE TASKS:
1. PLACE. See to it that the place for doing the task is conducive to work, well
ventilated, clean, and has good lighting. A space provided for freedom to
move is important. A place chosen will give you idea on what task is to be
done.

THE TASK TO BE DONE. YOU SHOULD BE CAREFUL ENOUGH TO
CHOOSE TOOLS AND EQUIPMENT THAT ARE WORTHY OF USE. THEY
MUST BE IN GOOD CONDITION SO THAT IT CAN BE EASILY UTILIZED
WITHOUT DAMAGING THE PARTS.
7. 4. SAFETY. ALWAYS PRIORITIZE SAFETY. REMEMBER THAT
ACCIDENT IS NOT AN EXCUSABLE INCIDENT. IT CAN BE
AVOIDED. ALWAYS REMEMBER THE MOTTO “SAFETY FIRST”.
8. 5. PROCEDURE/TASK. IDENTIFY WHAT TASK TO PERFORM BEFORE IDENTIFYING
MATERIALS AND TOOLS TO USE. THE SERVICE PROCEDURE/TASK TO EMPLOY
WILL TELL YOU THE CORRESPONDING TOOLS AND MATERIALS NEEDED.
APPROPRIATE TOOLS TO USE WITH THE TASK WILL ENHANCE YOUR ABILITY TO
PROVIDE A COMPETITIVE AND EFFICIENT SERVICE.
10. OCCUPATIONAL/ OPERATIONAL HEALTH AND SAFETY
(OHS)
Occupational/ Operational Health and Safety (OHS) is a
cross disciplinary area concerned with protecting the safety,
health and welfare of people engaged in work or
employment.
11. SAFETY PROCEDURES(OHS)
To prevent electrical shock hazard, disconnect the power cable
from the electrical outlet before relocating the system
When adding and removing devices to or from the system, ensure
that the power cables for the devices are unplugged before the
signal cables are connected. If possible, disconnect all power
cables from the existing system before you add a device
To avoid short circuits, keep paper clips, screws, and staples away
from connectors, slots, and sockets.
Avoid dust, humidity, and temperature extremes. Do not place the
product in any area where it may become wet
12. Always Pull the cable connector on the handle and not on the
cable itself .
Use only rubber shoes when standing on the ground or in a
concrete floor
Always power off and unplug the computer before working on it.
Take away any liquid such as mineral water or soft drinks near
your working area or near computers.
Contingency measures during workplace accidents, fire and other
emergencies are recognized.
13. SAFETY PRECAUTIONS
• Do not place any combustible materials near the power outlet.
• Avoid using power cord with defects such as loose contacts and exposed
conductors.
• Avoid using connecting wires with exposed conductors.
• Do all the wiring connection inside the computer system with the power off.
• Check the proper connections before turning the circuit power on.
• Remove any jewelry, which is conductive.
• Check your measuring instruments for proper voltage, current, resistance setting
before making any measurement.
• Refer to the mother manuals for its proper jumper setting and connection.
16. At the end of this module, you should be able to:
1.Identify the types of programs/ applications software
2.Check the accuracy of information and save the
information in accordance with standard operating
procedures
3.Classify the inputted data in storage media according to
requirements
17. HOW COMPUTER WORKS?
A computer is an electronic
machine made up of hardware
and software that work together
to do a task.
18. A SOFTWARE REFERS TO A PROGRAM OR APPLICATION INSTALLED INTO A
COMPUTER TO DO A SPECIFIC TASK. THE EXAMPLES ARE WORD PROCESSING
PROGRAM AND PRESENTATION PROGRAM.
19. A HARDWARE IS COMPUTER PARTS OR DEVICE THAT YOU CAN SEE
OR TOUCH.
23. 1) SYSTEM UNIT/COMPUTER CASING-THIS BOX IS WHERE ALL THE MAIN
COMPUTER COMPONENTS ARE HOUSED – MOTHERBOARD, PROCESSOR, MEMORY, HARD DISKS,
POWER SUPPLY, AND MORE.
24. MONITOR- ARE WHERE THE TEXT, IMAGES, AND VIDEOS ARE
DISPLAYED. SOME MONITORS MAY EVEN HAVE BUILT-IN SPEAKERS,
MUCH LIKE TELEVISIONS.
Planning plays the most important role of achieving a successful task. Your ability to plan properly will enable you to attain your target or purpose goal. Many successful entrepreneurs have realized their success through proper and careful planning. Likewise, aside from planning, you should also give importance to preparation. Good preparation will boost your confidence because it means that you are ready to do the task because you have sufficient knowledge about it. As a computer system servicing student, you also need to familiarize with the materials and tools involve in order to really attain the good result of the task given in avoidance of lagging when performing the task you are about to be undertaken.
Knowing OHS is essential to minimize the hazards and risks not only to students, trainers and other people within the training institution but others who will be affected.
Technology has become the integral part of modernization in our society. It opens door to information that will be needed by people who seeks knowledge through the use of computer. Using computer, people can search and gain information by simply accessing the internet. Just a click away, the information is being presented. The things that are presented in the computer is simply coming from people who puts information using computer. It is through the use of different programs/ applications software that could process the data being inputted by the person. In this lesson, you will learn more about how a computer works.

As a computer system servicing student, to attain the desired goal in the task given, you must also familiarize the components of the computer and how the computer works in order to avoid confusions.
Each hardware performs a specific function. It could be as an Input Device or as an Output Device.
But with today’s technology, tower casings are kind of losing popularity. Most people will likely prefer to use the “integrated, lightweight, and portable computers” – All-in-one PCs, laptops, tablets, and mobile devices.
P.S. If you have read other guides on the Internet, some people refer to this box as the “CPU” (central processing unit). That is wrong and has always been a major confusion – The CPU is actually a chip inside the casing itself.
The older designs of computer monitors run off a technology called cathode ray tube (CRT). As you can guess, those bulky and power-hungry displays have been totally taken over by the slim and lightweight liquid crystal display (LCD) or LED (light-emitting diode) displays.
