Digital Society: How Information Technology Changes Our Lives

A digital society (also called an information society) is a society where making, sharing and using information with computers and networks is a main part of life, work and government. Information moves fast, reaches everywhere and can be copied at almost no cost. Software has changed shopping, banking, health, school and friendship. New jobs appear (app developer, data analyst) while some old jobs shrink. Every online action leaves data, so privacy matters. Not everyone is connected (the digital divide), and too much screen time or gaming can harm health. A good digital citizen uses the benefits and manages the risks.

🎬 Step-by-step story

  1. Look at the timeline. First the printing press, then the telegraph, the computer, the internet and the smartphone. Each step made information travel faster.
  2. Today people are linked in a giant network. The yellow dot is a message. It crosses the world in under a second, day and night.
  3. Technology changes work. The red bars are jobs that are shrinking. The green bars are new jobs that are growing.
  4. Each time you use an app, you leave data: your location, photos, purchases. It flies to the cloud. The lock is your privacy setting.
  5. There are problems too. Grey homes are not connected: this gap is the digital divide. The clock shows hours lost to too much screen time.
  6. Your turn. Drag the slider to change how many homes are online. Count how many people are left behind.

Tip: drag the 3D scene to turn it. Use two fingers to zoom.

🤔 Common doubts, cleared

Was there no information before computers?

There was, but it moved slowly by hand, print or wire. Step 1 shows how each invention made it faster.

Why is it called a 'network society'?

Because people, computers and services are all linked and pass information to each other. See the linked dots in step 2.

Will computers take away all jobs?

No. Some shrink, but new ones grow and many simply change. Compare the red and green bars in step 3.

Where does my data actually go?

To computers (servers) owned by app companies, often called the cloud. Watch the coloured cubes fly up in step 4.

Why are some people still offline?

Cost of devices and data, no network in the area, or no one to teach the skills. Step 5 shows grey, unconnected homes.

What is an information (digital) society?

A society is a large group of people who live together and share rules. In an information society, creating and sharing information is a main activity, like farming was in the past and factories were later.

Features:

How software changed the world

Software is the set of instructions that tells a computer what to do. It changed many parts of life:

Search engines, social media and open-source software let people share knowledge and work together across the world.

Digital society and jobs

Computers do repeated tasks quickly. So some jobs shrink: typists, ticket counter clerks, some factory jobs. Automation means machines or software doing work people used to do.

New jobs grow: app and web developers, data analysts, cyber-security experts, online teachers, delivery and gig work through apps.

Many jobs change rather than vanish: a shopkeeper now also sells online. That is why lifelong learning (learning new skills all through life) matters.

Data, privacy and social change

Every search, click and payment creates data. Companies use it to improve services and to show adverts. Governments use it to plan roads and hospitals.

Privacy means control over your own information. Risks: data leaks, identity theft, tracking. Many countries now have data-protection laws that say companies must ask permission and keep data safe.

Data can change society for good (finding disease outbreaks early) or for harm (spreading fake news, unfair targeting).

Problems: digital divide and overuse

The digital divide is the gap between people who have devices, internet and skills and those who do not. It often follows income, age, gender and town versus village.

Overuse: too much gaming, scrolling or video can hurt sleep, eyes, posture, mood and study. Warning signs: losing track of time, feeling upset without the phone, skipping sleep or homework.

Healthy habits: set screen-time limits, keep phones out of the bedroom at night, take breaks every 30–40 minutes, and do real-world activities.

Try it at home

For one day, write down every digital service your family uses (payments, maps, video, messages). Next to each, write one benefit and one risk. Then check your phone's screen-time tool: how many hours did you use it yesterday? Set a goal for tomorrow.

Key formulas and definitions

Worked examples

1. Give two features of an information society with an example of each.

Speed: a WhatsApp message reaches another country in a second. Low cost copying: one online lesson video can be watched by a million students.

2. A railway reservation counter closes because people book online. Which jobs shrink and which grow?

Counter clerk jobs shrink. Jobs in app development, server maintenance and customer support for the online system grow.

3. A town where 40% of homes have no internet starts online-only school forms. What problem appears and how could it be fixed?

The digital divide: 40% of families are left out. Fix: keep a paper option, open help desks or free Wi-Fi at the school or library.
