Module 1: AI Basics

Course Introduction

Artificial Intelligence (AI) is becoming an important part of modern workplaces and everyday digital tools. From chatbots and search engines to email assistants and document summarisation, AI is already helping people perform tasks more efficiently.

This module provides a practical introduction to Artificial Intelligence, Generative AI, Large Language Models (LLMs), AI tools, practical workplace applications, AI limitations, and responsible AI use.

By the end of this module, learners will understand what AI is, how modern AI assistants work at a basic level, where AI can be used, and why human judgment and verification remain essential.

1. Foundations of Artificial Intelligence

What is Artificial Intelligence?

Artificial Intelligence (AI) is technology that enables computers and software systems to perform tasks that normally require human intelligence.

In simple words:

AI enables machines to perform tasks that appear intelligent or human-like.

AI is not limited to robots. It is already integrated into many everyday digital tools such as chatbots, search engines, email assistants, and other software applications.

What Can AI Do?

AI can assist with tasks such as:

• 
  Understanding language
  


• 
  Recognising patterns
  


• 
  Answering questions
  


• 
  Making predictions
  


• 
  Solving problems
  


• 
  Generating content
  


• 
  Analysing information
  


• 
  Translating languages
  


• 
  Supporting decisions
  

Simple Example

Suppose an employee asks an AI system:

"Write an email requesting leave for two days."

The system interprets the instruction, processes the request, and generates a suitable email draft.

AI in Everyday Tools

You may already encounter AI in:

• 
  Email spam filters
  


• 
  Smart-reply suggestions
  


• 
  Search engine suggestions
  


• 
  Grammar and writing assistants
  


• 
  Voice assistants
  


• 
  Automatically generated meeting summaries
  


• 
  Website chatbots
  

2. Why AI Matters at Work

AI is increasingly becoming an important workplace skill. It can reduce the amount of time spent on routine work and allow people to focus on more valuable activities.

Benefits of AI in the Workplace

1. Reduces Routine Work

AI can help reduce repetitive and low-value tasks.

2. Improves Communication

AI can assist with clearer and more thoughtful communication.

3. Supports Problem-Solving

By reducing routine workload, AI can give employees more time to focus on meaningful problems and collaboration.

AI Saves Time

Many office tasks can be repetitive and time-consuming. AI can help create a first draft within seconds.

Examples include:

• 
  Writing routine emails
  


• 
  Creating notices
  


• 
  Summarising documents
  


• 
  Preparing reports
  


• 
  Preparing meeting minutes
  


• 
  Improving grammar
  


• 
  Creating Excel formulas
  

Workplace Example

Instead of spending considerable time writing a reminder to faculty members about submitting marks, an employee can provide the important details to AI and receive a professional first draft.

The employee should then review, edit, and approve the final message.

Important: AI does not eliminate human work. It assists with repetitive tasks so humans can spend more time on important work.

3. AI as a Workplace Skill

AI literacy is becoming an important professional skill.

Employees who understand AI can:

• 
  Work faster
  


• 
  Communicate more effectively
  


• 
  Automate repetitive tasks
  


• 
  Analyse information efficiently
  


• 
  Create professional documents
  


• 
  Improve productivity
  

AI Literacy Means Knowing:

A person with basic AI literacy should understand:

1. 
   What AI is
   


2. 
   What AI can do
   


3. 
   How to give instructions to AI
   


4. 
   How to check AI-generated information
   


5. 
   How to use AI responsibly
   


6. 
   When human judgment is necessary
   

4. Generative AI

What is Generative AI?

Generative AI is a type of artificial intelligence that can create new content rather than simply analysing existing information.

Generative AI can create:

• 
  Emails
  


• 
  Reports
  


• 
  Images
  


• 
  Ideas
  


• 
  Summaries
  


• 
  Presentations
  


• 
  Computer code
  


• 
  Other types of content
  

Traditional AI vs Generative AI

For example, traditional AI might identify whether an email is spam, while Generative AI might create a professional response to that email.

5. Understanding Large Language Models (LLMs)

Many modern AI assistants are based on Large Language Models (LLMs).

An LLM is an AI system designed to work with human language.

An LLM can:

• 
  Read text
  


• 
  Understand instructions
  


• 
  Generate text
  


• 
  Summarise information
  


• 
  Rewrite content
  


• 
  Translate languages
  


• 
  Answer questions
  


• 
  Draft documents
  

Easy Analogy

Think of an LLM as a highly-read office assistant that has been exposed to a huge amount of written material.

It can predict what words or responses are likely to come next.

However, an LLM should not be treated exactly like a database containing verified facts.

An AI response can:

• 
  Sound professional
  


• 
  Look logical
  


• 
  Be grammatically correct
  

…and still contain incorrect information.

Key Principle

A confident AI answer is not necessarily a correct answer.

6. AI Hallucinations

One of the important limitations of Generative AI is AI hallucination.

An AI hallucination occurs when AI generates information that is:

• 
  Incorrect
  


• 
  Unsupported
  


• 
  Invented
  

while presenting it as though it were true.

Example

You ask:

"Give me the official date of a university examination."

AI may provide a specific date that appears realistic but is actually incorrect.

Therefore, AI-generated information should follow this process:

Generated → Reviewed → Verified → Edited → Used

It should not follow:

Generated → Copy → Send

Golden Rule

Always verify AI-generated facts, names, dates, and figures before using them, especially for official work.

7. Major AI Tools

The goal is not to depend on one AI tool. The goal is to understand which tool is appropriate for a particular task.

9. Practical Applications of AI

AI can support many common workplace activities.

9.1 Writing Emails

AI can help create:

• 
  Formal emails
  


• 
  Reminder emails
  


• 
  Invitations
  


• 
  Leave-request emails

Example:

"Write a polite reminder to faculty members to submit internal assessment marks by Friday."

AI can create the initial draft.

9.2 Summarising Documents

AI can convert long documents into:

• 
  Key points
  


• 
  Short summaries
  


• 
  Bullet points
  


•

For example, a 10-page policy document can be transformed into key points, deadlines, and responsibilities.

9.3 Generating Reports

AI can help create the initial structure for:

• 
  Monthly reports
  


• 
  Meeting reports
  


• 
  Activity reports
  


• 
  Department reports
  

It can organise information into clear headings and sections.

• 
  Slide structures
  


• 
  Slide headings
  


• 
  Bullet points
  


• 
  Speaker notes
  


• 
  Example ideas
  

Human review is still necessary.

9.5 Translation

AI can translate content between languages, such as English ↔ Hindi.

Official translations should still be reviewed.

9.6 Grammar Improvement

AI can improve:

• 
  Grammar
  


• 
  Spelling

• 
  Official notices
  


• 
  Circulars
  


• 
  Letters
  


• 
  Internal memos
  


• 
  Announcements
  

These should always be human-checked before use.

10. The Basic AI Working Process

A beginner can understand AI through a simple three-stage process:

Stage 1: Input / Prompt

You provide instructions to the AI.

Example:

"Write a professional email to teachers about tomorrow's staff meeting."

↓

Stage 2: AI Processing

The AI interprets the instruction and generates a response based on patterns learned during training and the conversation.

↓

Stage 3: Output

The AI produces the requested:

• 
  Email
  


• 
  Answer
  


• 
  Summary
  


• 
  Report
  


• 
  Formula
  


• 
  Ideas
  


• 
  Other content
  

Basic Model

Your Instruction → AI Processing → AI Response

The quality of the final result depends heavily on how clearly you communicate your requirement.

11. AI Cannot Read Your Mind

An important beginner concept is that AI does not automatically know what you want.

Poor Instruction

"Write an email."

AI does not know:

• 
  What type of email?
  


• 
  Who is the recipient?
  


• 
  What is the purpose?
  


• 
  Should it be formal or informal?
  


• 
  What information should be included?
  


• 
  How long should it be?
  

Better Approach

Tell AI:

• 
  Role – Who should AI act as?
  


• 
  Task – What should it do?
  


• 
  Background – What information does it need?
  


• 
  Tone – How should it sound?
  


• 
  Format – How should the answer be presented?
  


• 
  Details – What specific information must be included?
  

This concept leads directly to the next module: Prompt Writing.

12. AI as an Assistant, Not a Decision-Maker

One of the most important principles of using AI is:

AI = Assistant

Human = Decision-Maker

AI can:

• 
  Suggest
  


• 
  Draft
  


• 
  Organise
  


• 
  Summarise
  


• 
  Analyse
  


• 
  Improve
  

Humans should decide:

• 
  What is correct
  


• 
  What should be sent
  


• 
  What action should be taken
  


• 
  Whether information is appropriate
  


• 
  Whether a decision is acceptable
  

Example

AI may draft an examination notice.

Before sending it, the employee must verify:

• 
  Date
  


• 
  Time
  


• 
  Venue
  


• 
  Department
  


• 
  Faculty names
  


• 
  Contact information
  

13. Responsible AI Use

AI should always be used responsibly.

The three important principles are:

Privacy + Accuracy + Professional Responsibility

Convenience should never be more important than these principles.

Always Do

✔ Verify facts

✔ Protect confidential organisational information

✔ Protect personal data

✔ Proofread AI-generated content

✔ Maintain human control

✔ Use AI as an assistant rather than replacing human judgment

Never Do

✘ Share confidential information

✘ Upload student or personal records

✘ Upload passwords or login credentials

✘ Blindly trust AI answers

✘ Copy AI output without proofreading

14. Practical Workplace Example

Scenario

An employee needs to send an examination reminder.

Without AI

1. 
   Think about the wording
   


2. 
   Draft the email
   


3. 
   Check grammar
   


4. 
   Format the message
   


5. 
   Review it
   


6. 
   Send it
   

With AI Assistance

1. 
   Provide the situation to AI
   


2. 
   AI creates a draft
   


3. 
   Employee reviews the draft
   


4. 
   Employee verifies dates and details
   


5. 
   Employee edits the final version
   


6. 
   Employee sends the email
   

Key Lesson

AI can reduce the drafting effort, but the employee remains responsible for the final communication.
