What I Need to Know
OCCUPATIONAL HEALTH AND SAFETY POLICIES AND PROCEDURES
During installation and initial test, careful planning and preparation are to be done. To
avoid personal injury and damages to wiring due to sharp pins on connectors and printed
circuit assemblies, rough chassis edges and corners, and hot components.
Adhere to warnings and limitations regarding accessibility into areas designated only
for authorized technical personnel.
SOME BASIC PRECAUTIONS AND PROCEDURES:







Before starting the installation, read carefully the documentation and procedures on
any hardware and software settings that may be required.
Failure to do the proper jumper setting may cause damage to your CPU.
Without an effective cooling fan, the CPU can overheat and cause damage to both
CPU and the motherboard.
Each bank must have the same size and type of memory installed in pairs.
Before adding and removing any other system components, make sure that you unplug
your power supply. Failure to do so may cause damage to your motherboard and in the
system component.
Test the computer, ensuring that it meets the necessary system requirements before
booting up.
If the computer does not pass any of the power on self-test (POST), the computer will
receive an irregular power on self-test. An irregular POST is a beep code which is
different from the standard beep which can either be no beeps at all or a combination
of different beeps.

EFFECTS OF COMPUTERS
Some effects of computers relating to the violation of privacy, the impact on the labor
force, health risks, and the impact on the environment.
1. Violation of Privacy
Nearly every life event is stored in a computer somewhere--in medical records,
credit reports, tax records, etc. It is crucial that personal and confidential records be
protected properly. In many instances, where these records were not properly
protected, individuals have found their privacy violated and identities stolen.
2. Health Risks
Prolonged or improper computer use can lead to injuries or disorders of the hands,
wrists, elbows, eyes, necks, and back. Computer users can protect themselves from these
health risks through proper workplace design, good posture while at the computer, and
appropriately spaced work breaks. Another health risk, called computer addiction, occurs
when someone becomes obsessed with using the computer. Once recognized, computer
addiction is a treatable disorder.
3. Public Safety
Adults, teen, and children around the world are using computers to share publicly their
photos, videos, journals, music, and other personal information. Some of these
unsuspecting, innocent computer users have fallen victim to crimes committed by
dangerous strangers. Protect yourself and your dependents from these criminals by being
cautious. For example, do not share information that would allow others to identify or locate
you.
4. Impact on Environment
Computer manufacturing processes and computer waste are depleting natural
resources and polluting the environment. The amount of resources required to
manufacture a personal computer equals that of a mid-sized car. When computers are
discarded in landfills, they release toxic materials and potentially dangerous levels of lead,
mercury, and flame retardants. Strategies that can help protect the environment include
recycling, regulating manufacturing processes, extending the life of computers, and
immediately donating replaced computers.

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

What I Need to Know
Basic Hardware Components of Computer System
A computer is an electronic machine, operating under the control of instructions stored in its
own memory, that can be programmed to accept data (input), process it into useful information
(output), and store it away in a secondary storage device (store) for safekeeping or later reuse.
The processing of input into output is directed by the software but performed by the hardware.
Figure below shows some common computer hardware components.
Commons.wikimedia.org
https://bit.ly/352JmZu
Common Computer Hardware Components
Computer system hardware components
include devices that perform the functions of input,
processing,
data
storage;
output
and
communication. The devices responsible for these
five areas are as follows:
Input devices. Input devices allow you to enter
data or commands in a form that the computer can
use; they send the data or commands to the
processing unit. Commonly used input devices
include keyboard, mouse, microphone, scanner,
digital camera, and PC camera.
https://bit.ly/3l2s7wM
8
Output devices. Output devices show people the
processed data—information. In understandable
and useful form. Four commonly used output
devices are a printer, a monitor, speakers, and a
portable media player. Input/output devices are
playing an increasingly significant role in our lives.
The number and variety of input/output devices are
expanding.
https://bit.ly/3l2s7wM
Processing devices. Processing devices are the computer electronic circuitry housed in the
system unit. The processor, formally known as the central processing unit (CPU), has
electronic circuitry that manipulates input data into the information people want. Computer
instructions are actually are executed in the central processing unit. Memory is a series of
electronic elements that temporarily holds data and program instructions while they are being
process by the CPU. Both the processor and memory consist of chips. A chip is an electronic
device that contains many microscopic pathways designed to carry electrical current.
Storage devices. Storage usually means secondary
storage that can store data and programs outside the
computer itself. Storage devices hold data, information,
and programs permanently. Common storage devices
include a hard disk, USB flash drives, CDs, DVDs, and
memory cards.
https://bit.ly/38bJd7Y
Communications devices. Communications devices provide connections between
the computer and communications networks, and enable computer users to
communicate and to exchange data, information, and programs with other computers.
Communications devices transmit these items over transmission media such as
cables, telephone lines, satellites, and cellular radio. A widely used communications
device is a modem.

What I Need to Know
Perform BIOS Configuration
BIOS stands for Basic Input Output System. It
is also known as the system BIOS. It is a set of
routine programs shared on a chip on the
motherboard. The BIOS enables the OS to talk
to the hardware of the computer. A BIOS chip
is shown below.
The three subsystems of a BIOS are:
1. ROM BIOS
2. CMOS or BIOS setup
3. Plug-and-Play (PnP) BIOS
https://bit.ly/3parKD5
BIOS has a Set-up utility stored in the BIOS flash memory. The configured data is
provided with context-sensitive Help and is stored in the system’s battery-backed CMOS RAM.
If the configuration is stored in the CMOS RAM is invalid, the BIOS setting default to the
original state specified at the factory.
20
The BIOS setup or CMOS setup contains a setup program to configure settings for the
hardware devices. The configuration data is saved to a memory chip called a Complimentary
Metal Oxide Semiconductor (CMOS). The BIOS program usually has the following menu items:
- Main
- Advanced
- Boot
- Security
- Power
- Exit
https://bit.ly/3eujhWl
Common options that you can make changes to include:
a. System Time/Date – Set the system time and date
b. Boot Sequence – The order that BIOS will try to load the OS
c. Plug and Play – A standard for auto-detecting connected devices; should be set to
“Yes”
d. Mouse/Keyboard – “Enable Num Lock”, “Enable the Keyboard”, “Auto-Detect Mouse”,
etc.
e. Drive Configuration – Configure hard drives, CD-ROM and floppy drives
f. Memory – Direct the BIOS to shadow a specific memory address
g. Security – Set a password for accessing the computer
h. Power Management – Select whether to use power management, as well as set the
amount of time for standby and suspend
The following information are shown at the BIOS Configuration:




CPU manufacturer name, CPU speed
RAM manufacturer, RAM speed, number of memory slots
Hard drive manufacturer, size, type. And number of hard disk controllers
Optical drive manufacturer and type Common security features found in the BIOS are:
1. Supervisor Password – this allows access to all settings and user-password
2. User Password – this defines the access level of user to the BIOS setup screen.
Four access levels available are full access, limited access, view-only access and
no access.
3. Data Encryption – sets encryptions of the data on the hard disk. Encryption
changes data into code that cannot be understood by other systems.
4. Lojack – this allows a lost computer to contact an agent in the event that the
computer is lost/stolen. The agent can:
o Lock the computer remotely
o Display a message to ask that computer be returned to the owner
o Delete sensitive data
o Locate computer using geotechnology
21
The BIOS has hardware monitoring features. It collects information on the hardware
or of the motherboard. Some of the information collected include:
1. Temperature of the CPU, if the CPU gets to hot, it might be shut down by the system
2. Temperature of the PSU, if it gets too hot, the system will shut down automatically
3. Speed of the cooling fan, this speed will be adjusted according to the temperature of
the other hardware
4. Voltage of the CPU, if the voltage is too high, the CPU can be damaged
5. Bus speed
Built-in BIOS diagnostics allow you to run tests to identify problem areas. These tests
include:
 Start Test – this test checks to see if the main components are working normally. It
should be run when the computer does not boot normally.
 Hard Drive Test – this test checks the hard drive for damaged areas
 Memory Module Test – this test checks the memory modules for normal operation
 Battery Test – this test checks if the battery is in normal operating condition. If it is
not, it should be replaced with a new, working battery.
What I Can Do
Additional Information: Research the following.
1. How do you set BIOS to default setting?
2. What key will you press to enter BIOS?
3. What happens when you reset BIOS?
4. What is the main function of BIOS?
5. Why can’t you access BIOS directly from within the Windows?
