MODULE 5 – INFORMATION TECHNOLOGY & SOCIETY
(Full Detailed Teaching Notes in Simple Words — Nothing Skipped)
1. What is Information Technology (IT)?
IT means using computers, networks, and communication systems to store, retrieve, and send
information.
It includes hardware, software, internet, data storage, security systems, and everything used to
manage digital information.
IT is mainly used for business operations, not entertainment. It helps organizations work faster and
safer.
2. What IT Includes
- Computers and servers
- Storage devices
- Networks and communication systems
- Security and data protection tools
- Software used in companies
This makes IT important for almost all industries—banking, railways, airlines, hospitals, government,
and more.
3. Major Roles of an IT Department
1. Deploys and maintains systems:
• Installs business applications, servers, storage, and networks.
• Ensures software and hardware work properly together.
2. Monitors, optimizes, and troubleshoots:
• Checks system performance.
• Fixes crashes, slowdowns, and failures.
• Ensures smooth daily operations.
3. Oversees security and governance:
• Protects data from hacking and misuse.
• Detects unauthorized access attempts.
• Makes sure the company follows safety rules and policies.
4. Examples of IT in Real Workplaces
A. Security Monitoring
• IT systems watch activity happening in networks and apps.
• If someone tries to open a restricted file, IT receives an alert.
• They check logs, find the root cause, and fix the issue.
• This improves long-term security.
B. New Software Development
• Business decides to build a mobile app.
• Developers create and update the app.
• Operations team uploads new versions and manages servers.
• IT ensures the backend works properly.
5. IT Degree Subjects
- Business analysis
- Project management
- Telecommunications
- Network administration
- Database design
- Database management
These subjects teach students to understand business needs, manage systems, and work with data.
6. Information Technology Act 2000
Purpose:
• Gives legal recognition to digital signatures and electronic records.
• Makes online contracts legally valid.
• Supports electronic filing with government agencies.
• Amended IPC, Evidence Act 1872, Banker’s Books Act 1891, and RBI Act 1934.
• Main Indian law for cybercrime.
Importance:
Before this act, digital documents had no legal value. Now online transactions, emails, and digital
signatures are accepted legally.
7. Intellectual Property Rights (IPR)
Definition:
IPR gives creators legal rights to protect their inventions or works for a limited time. These rights stop
others from copying or misusing the creation.
IP is intangible — it cannot be touched.
Examples: artworks, brand logos, inventions, software, product designs.
Key Points:
- IPR protects creativity.
- Some IPR expires (copyright, patent), some can last forever (trademark with renewal).
- Unauthorized use is called infringement.
8. Types of IPR
A. Copyright
• Protects original content such as books, music, videos, software.
• Only owner can copy or distribute.
Example: You cannot copy someone’s song or drawing without permission.
B. Patent
• Protects new inventions.
• Normally valid for 20 years.
• Prevents others from making or selling the invention.
Example: A new machine, medicine formula.
C. Trademark
• Protects brand names, symbols, and logos.
• Helps identify products.
Example: Nike logo ✓.
D. Performers’ Rights
• Protects live performances.
• Others cannot record or reproduce a performance without permission.
E. Database Rights
• Protects databases.
• Fair use allowed for teaching or research (not for commercial use).
F. Design Right
• Protects the physical appearance of a product.
Example: furniture shape, car body design.
9. Applications of IT in Railways
- Online reservation system (IRCTC)
- Live train status and PNR checking
- Seat availability information
- Route-based ticketing: tickets from any station → any station
- Multi-lap journey tickets
- 24x7 service availability
- Automatic database recovery during failures
IT makes railway services faster, reliable, and widely accessible.
10. Applications of IT in Airlines
- Reservation and ticketing systems
- Inventory management (seats, baggage, cargo)
- Worldwide communication between airline branches
- IT improves safety, efficiency, and performance in aviation
- Helps air traffic management through real-time updates
Aircraft, airline operations, and air traffic control form a connected system that uses IT for decisions.
11. Applications of IT in Banking
Indian banks use many IT systems:
- NEFT (National Electronic Funds Transfer)
- RTGS (Real Time Gross Settlement)
- ECS (Electronic Clearing Service)
- Cheque Truncation System
- Mobile banking, debit/credit cards, prepaid cards
Electronic Fund Transfer (EFT):
• Money transfer between accounts without staff involvement.
Customer Services through IT:
- SMS/email alerts
- Online balance check
- View statements
- Pay bills online (electricity, telephone, water)
- Fixed deposit enquiry
- Cheque status enquiry
12. Applications of IT in Insurance
- Faster customer service
- Accurate data instantly available
- Quick responses to customer needs
- Better digital data management
Insurance companies no longer depend on paperwork; IT makes everything faster.
13. Applications of IT in Inventory Control
Benefits:
- Inventory software tracks stock efficiently.
- Helps make better decisions using data.
- Smartphones/tablets allow remote access.
- Increases accuracy and speed.
Challenges:
- Technical problems: bugs, glitches, compatibility issues.
- Data security risks.
- High cost: requires training and updates.
- New technology may require investment.
Businesses must use inventory technology carefully and plan for upgrades.
