This document provides information on performing computer operations and inputting data into computers. It discusses planning tasks by considering factors like safety, tools, and procedures. It describes occupational health and safety guidelines for working with computers, including preventing electric shock and keeping computers dry. The document also explains how computers work by discussing software, hardware, input/output devices, and basic computer components like the system unit, motherboard, CPU, RAM, graphics card, and cooling systems. It provides details on the functions of these core internal computer parts.

1. PERFORMING COMPUTER OPERATIONS
MODULE 2

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

3. LESSON 1.
Plan and Prepare for Task to be
Undertaken

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.

5. 2. WASTE DISPOSAL. USED WIRE OR WIRE STRIPS OR OTHER THINGS
THAT CAN’T BE USED ANYMORE MUST BE DISPOSED IN PROPER
STORAGE BIN OR CONTAINER.

6. 3. TOOLS/EQUIPMENT. TOOLS AND EQUIPMENT MUST MATCH WITH
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.

14. LESSON 2
INPUT DATA INTO COMPUTER

15. GUESS ME??

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.

20. INPUT DEVICES-any hardware components that allows
you to enter data and instructions into a computer.

21. OUTPUT DEVICES- ANY DEVICE USED TO SEND DATA
FROM A COMPUTER TO ANOTHER DEVICES OR USER.

22. BASIC PARTS OF COMPUTER AND ITS
FUNCTIONS

23. 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.

25. KEYBOARD-USED TO TYPE AND ENTER DATA WITH THIS DEVICE. THE
MOST COMMON KEYBOARD LAYOUT IN THE WORLD IS QWERTY.

26. MOUSE-A POINTING DEVICE THAT WE USE TO MOVE THE CURSOR
ON THE SCREEN, THE MOUSE BUTTONS ARE USED TO INTERACT
WITH VARIOUS ON-SCREEN ELEMENTS.

27. UPS (UNINTERRUPTIBLE POWER SUPPLY)-ALSO KNOWN AS A
BATTERY BACKUP, PROVIDES BACKUP POWER WHEN YOUR REGULAR
POWER SOURCE FAILS OR VOLTAGE DROPS TO AN UNACCEPTABLE
LEVEL.

28. INSIDE THE SYSTEM UNITS

29. POWER SUPPLY UNIT (PSU)-THIS IS THE COMPONENT THAT
CONVERTS POWER FROM THE WALL OUTLET TO ONE THAT THE
COMPUTER NEEDS.

30. MOTHERBOARD-THE HEART AND BIGGEST CIRCUIT BOARD OF THE
COMPUTER. ALL THE COMPONENTS AND DEVICES ARE CONNECTED
TO THE MOTHERBOARD.

31. CPU-IT IS THE BRAIN OF THE COMPUTER WHERE ALL DATA
CRUNCHING AND PROCESSING IS DONE.

32. HARD DISK DRIVE (HDD)-THE HARD DISK IS WHERE DATA IS
PERMANENTLY STORED – THE OPERATING SYSTEMS, THE
APPLICATIONS, YOUR PICTURES, MUSIC, DOCUMENTS, AND MORE.

33. RANDOM ACCESS MEMORY (RAM)-IT IS ALSO USED FOR DATA
STORAGE, BUT TEMPORARILY (POWER OFF AND ALL DATA IN THE
RAM WILL BE LOST).

34. GRAPHICS CARD-IT PROCESSES ALL “GRAPHIC THINGS” FOR
GAMING, VIDEO, AND PHOTO EDITING.

35. FANS & HEATSINKS-USED TO COOL THE COMPONENTS, TO
PREVENT A MELTDOWN FROM OCCURRING.
