The document provides instructions for performing computer operations safely and effectively. It discusses selecting an appropriate work place, properly disposing of waste, choosing the right tools for the job, prioritizing safety, identifying the correct procedure, and inputting data into the computer. Safety should always be the top priority when working with tools and equipment. The proper tools and materials must be selected based on the specific task to be completed.

1. PERFORMING COMPUTER
OPERATIONS

2. 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.

3. 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.

4. • 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.

5. A tool is a handheld device that aids in accomplishing a task.
Tools range from a traditional metal cutting part of a machine to an element of a computer
program that activates and controls a particular function.
Preparing for the task to be undertaken includes proper tool selection.
1.How do you select the best tool for the job? First, know and understand in detail the scope of
work to be accomplished, second, plan for the scope considering the sequence of tasks.
2.Selecting the best tool for each task requires training in the proper use of the tools, field
experience in their safe use, and following the manufacturer’s guidance and instructions for that
specific tool.
3.When obtaining the tool all the associated tooling and consumable parts, as recommended by
the manufacturer, must be included.
In addition, related consumable parts must also be selected and used according to their
manufacturer’s instructions.

6. SAFETY. Always
prioritize safety.
Remember that
accident is not an
excusable incident. It
can be avoided.
Always remember
the motto “Safety
first”.

7. 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
task will enhance your ability to provide a competitive and efficient service.

INTO
COMPUTER

10. How Computer Works?
A computer is an electronic machine made up of
hardware and software that work together to do a
task.
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.

11. A HARDWARE IS
COMPUTER PARTS
OR DEVICE THAT
YOU CAN SEE OR
TOUCH.

12. What is Data?
Data is a collection of facts and figures, such as values or
measurements.
The data is the raw material to be processed by a computer.
Data versus Information
When data are processed, interpreted, organized, structured or
presented so as to make them meaningful or useful, they are called
information

14. Types of Data
Numeric data
• The data which is represented in the form of numbers
• This includes 0-9 digits, a decimal point (.) +, /, - sign and the
letters “E” or “D”.

15. CHARACTER DATA

16. Data Processing Cycle
- Data processing is simply the conversion of raw data to meaningful information
through a process.
- The data is processed again and again until the accurate result is achieved.
Input
- Input is the task where verified data is coded or converted into
machine
- readable form so that it can be processed through a computer

17. A hardware is an input device if it is used to
enter data or give commands to the computer.
Two of the most common input devices are
keyboard and mouse. A keyboard is an input
device because if you want to enter data to the
computer, we have to press the keys or each
letter, numbers or special keys. A mouse is also
an input device because if you want to give
instruction to the computer, we have to press its
buttons.

18. Processing
- Processing is when the data is subjected to various means and methods of
manipulation, the point where a computer program is being executed, and it
contains the program code and its current activity.
• Classifying
• Sorting
• Calculating
• Summarizing
• Comparing

19. Output
- Output is presented to users in various report formats like printed
report, audio, video or on monitor.
• Text
• Graphics
• Audio
• Video
A hardware is an output device if it gives the results done by the
computer. Some of the common devices are: monitor, which displays
the text, graphics and documents done in the computer; the printer, it
prints on the paper the text and graphics that you have inputted to.
Speakers and headphones are output device because through them
you could hear sounds and music coming from your computer

20. Storage
- Storage is a location which data instruction and in
which data, instruction and information are held for
future use
- Every computer uses to hold system software and
application software
- A storage medium, also called secondary storage is
the physical material in the computer that keeps data,
instruction and information.

21. TYPES OF DATA
PROCESSING

22. Manual Data Processing
The process of data entry implies many opportunities for errors, such
as:
• Delays in data capture
• A high amount of operator misprints,
• High labor costs from the amount of manual labor required etc.
