This chapter helps us understand how technology should be used responsibly and ethically.
5.1 Introduction to Information Technology
Information Technology is concerned with the study, design, development, implementation, support and management of computer-based information systems, particularly software applications and computer hardware.
In today's world, Information Technology has a huge effect on human life. Many activities that were previously performed manually are now done electronically.
Examples include:
- Making notes
- Preparing reports
- Maintaining daily transaction records
- Business activities
- Government services
- Transportation
- Factory operations
The chapter also points out that Information Technology is developing very rapidly. Computers and mobile devices have become smaller and faster, while the Internet has brought major changes to IT.
📖 Key Idea
Information Technology has changed the way people work, communicate, store information and perform everyday activities.
5.2 Ethics in Information Technology
Information Technology has become an important part of modern life. It affects areas such as medicine, transportation, banking, government, security and research.
Technology can affect people and society in both positive and negative ways. It also raises questions about what is right and wrong in areas such as community life, education, relationships, law and other aspects of society.
The Internet has made a major impact on global communication. It has made it possible for people to share information, find information online and perform activities such as online shopping and online grocery shopping.
Online banking has also made it possible for people to manage many daily transactions without visiting a bank physically.
However, the rapid advancement of technology can also make unethical and criminal activities more sophisticated. Therefore, knowledge of security issues, privacy issues and the negative impacts of IT is important.
💡 Remember
Computer ethics deals with the responsible and proper use of computers, information technology and digital resources.
5.3 Plagiarism
Plagiarism is the act of stealing someone else's ideas or work and presenting them as your own.
It can involve copying:
- Text
- Media
- Ideas
- Images
- Other people's creative work
When another person's work is copied and republished without an appropriate reference or citation, it is considered plagiarism.
The Internet has made information easier to access. At the same time, it has also made it easier to copy large amounts of text or images from another source.
Plagiarism may happen intentionally or unintentionally. For example, a student may deliberately copy another person's work, or may accidentally copy information without properly acknowledging the source.
📖 Definition
Plagiarism is presenting another person's ideas, words or work as your own without proper acknowledgement.
5.3.1 Is Plagiarism a Crime?
Plagiarism is considered a violation of academic integrity and a breach of journalistic ethics.
Plagiarism itself is generally not a crime in every situation. However, depending on the circumstances, copyright infringement and violation of moral rights can have legal consequences.
⚠️ Important
Plagiarism is not simply a matter of copying. It is an ethical issue because another person's work is presented without proper acknowledgement.
5.3.2 Types of Plagiarism
The chapter describes four common types of plagiarism.
| Type | Description |
|---|---|
| Direct Plagiarism | Copying complete sentences or paragraphs written by someone else without attribution or quotation marks. |
| Mosaic Plagiarism | Lifting phrases from a source without using quotation marks or replacing certain words with synonyms while retaining the original structure and meaning. |
| Self-Plagiarism | Reusing one's previous work, such as submitting parts of an earlier paper or thesis again without appropriate permission or acknowledgement. |
| Accidental Plagiarism | Plagiarism that occurs accidentally, such as forgetting to cite a source, misquoting a source or failing to attribute a paraphrased section. |
1. Direct Plagiarism
Direct plagiarism occurs when complete sentences or paragraphs are copied from another person's work without giving proper credit or using quotation marks.
Example: Copying a paragraph from a website and submitting it as your own school assignment without mentioning the source.
2. Mosaic Plagiarism
Mosaic plagiarism occurs when phrases are taken from a source without quotation marks or when some words are replaced with synonyms while keeping the original structure and meaning.
Example: Changing a few words in a paragraph copied from another source while keeping the original sentence structure and meaning.
3. Self-Plagiarism
Self-plagiarism occurs when a person reuses their own previous work without appropriate permission or acknowledgement.
Example: Submitting a previous assignment again as a new assignment without permission.
4. Accidental Plagiarism
Accidental plagiarism occurs unintentionally. It may happen when a person forgets to cite a source, misquotes information or paraphrases material without giving proper credit.
Example: Using information from a magazine or website in an assignment but forgetting to mention the source.

In Part 2, we will cover:
- Why Should You Avoid Plagiarism?
- Guidelines for Avoiding Plagiarism
- Intellectual Property Rights
- Copyright
- Trademarks
- Patents
5.3.3 Why Should You Avoid Plagiarism?
Plagiarism is an ethical issue. When a person submits someone else's work as their own with the intention of benefiting from it, they are committing an ethical violation.
This applies to students submitting school assignments as well as writers using another person's work for personal or financial benefit.
⚠️ Why is Plagiarism Wrong?
- It takes credit away from the original creator.
- It violates academic and professional ethics.
- It can involve copyright or other intellectual property issues.
- It prevents a student or writer from developing original ideas.
How to Avoid Plagiarism
The chapter provides several guidelines that can help us avoid plagiarism when using information or ideas from other sources.
1. Cite Your Source
When using an idea or wording that is not your own, add a citation that identifies the source. The citation should provide the relevant information about where the material came from.
Remember: Always acknowledge the source when you use another person's information or ideas.
2. Include Quotations
If you use the exact words of a source in your writing, place those words inside quotation marks and identify the source.
Example: When directly using someone's words, use quotation marks instead of presenting those words as your own.
3. Paraphrase the Right Way
Paraphrasing means rewriting information or an idea in your own words without changing its original meaning.
However, simply replacing a few words with synonyms is not enough. Incorrect paraphrasing can still result in plagiarism.
Important: A proper paraphrase should genuinely express the source's idea in your own words while still acknowledging the source when required.
4. Present Your Own Idea
Instead of simply repeating another person's ideas, try to develop and present your own thoughts, observations and perspectives.
Ask yourself what unique point of view or contribution you can add to your writing.
📝 Four Ways to Avoid Plagiarism
| Method | What You Should Do |
|---|---|
| Cite Your Source | Acknowledge where the information or idea came from. |
| Use Quotations | Use quotation marks when directly using another person's words. |
| Paraphrase Correctly | Rewrite the information in your own words without changing its meaning. |
| Present Your Own Idea | Contribute your own thoughts and perspective. |
5.4 Intellectual Property Rights
Property is something over which a person can have rights and which is protected by law. Similarly, ideas and creative works produced by the human mind can also be protected by law.
Intellectual Property (IP) refers to creations of the mind, including inventions, literary works, images, symbols and other creative works.
With the development of the Internet, laws surrounding intellectual property have become increasingly important. Intellectual property rights allow the owner of information or creative work to control how that work is exchanged, shared or distributed.
📖 Definition
Intellectual Property Rights are legal rights that protect creations of the human mind, such as inventions, literary works, images and symbols.
Three Important Types of Intellectual Property Protection
