3. Advantages and Disadvantages of Using
Computers
 Society has acquired many benefits from using computers.
 A user is anyone who communicates with a computer or
utilizes the information it generates.
 Both business and home users can make well informed
decisions because they have instant access to information
from anywhere in the world.
 Students, another type of user, have more tools to assist
them in the learning process.

4. Advantages of Using Computers
 The benefits from using computers are possible because
computers have the advantages of;
1. speed
2. reliability
3. consistency
4. storage
5. and communications

5. Speed
 When data, instructions, and information flow along
electronic circuits in a computer, they travel at incredibly
fast speeds.
 Many computers process billions or trillions of operations
in a single second.

6. Reliability
 The electronic components in modern computers are
dependable and reliable because they hardly ever break
or fail.

7. Consistency
 Given the same input and processes, a computer will
produce the same results — consistently.
 Computers generate error-free results, provided the input
is correct and the instructions work.

8. Storage
 Computers store huge amounts of data and make this data
available for processing anytime it is needed.

9. Communications
 Most computers today can communicate with other
computers, often wirelessly.
 Computers allow users to communicate with one another.

10. Disadvantages of Using Computers
 Some disadvantages of computers relate to the
following;
 violation of privacy
 public safety
 impact on the labor force
 health risks
 impact on the environment

11. Violation of Privacy
 In many instances, where personal and confidential
records stored on computers were not protected properly,
individuals have found their privacy violated and
identities stolen.
Manolo L. Giron RMTU

12. Public Safety
 Adults, teens, 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.
Manolo L. Giron RMTU

13. Impact on Labor Force
 Although computers have improved productivity and
created an entire industry with hundreds of thousands of
new jobs, the skills of millions of employees have been
replaced by computers.
 Thus, it is crucial that workers keep their education up-
to-date.
 A separate impact on the labor force is that some
companies are outsourcing jobs to foreign countries
instead of keeping their homeland labor force employed.

14. Health Risks
 Prolonged or improper computer use can lead to health
injuries or disorders.
 Computer users can protect themselves from health risks
through proper workplace design, good posture while at
the computer, and appropriately spaced work breaks.
 Two behavioral health risks are computer addiction and
technology overload.
 Computer addiction occurs when someone becomes
obsessed with using a computer.
 Individuals suffering from technology overload feel
distressed when deprived of computers and mobile
devices.Manolo L. Giron RMTU

15. Impact on Environment
 Computer manufacturing processes and computer waste
are depleting natural resources and polluting the
environment.
 Green computing involves reducing the electricity
consumed and environmental waste generated when using
a computer.
 Strategies that support green computing include recycling,
regulating manufacturing processes, extending the life of
computers, and immediately donating or properly
disposing of replaced computers.
