Computer science is often associated with school lessons, programming, or calculations. However, the world of computer science is much broader and deeper. It’s not just a school subject—it’s present in our everyday lives, often in ways we don’t even realize. Moreover, understanding its principles is a skill that opens doors to many modern professions and solutions that make life easier. Let’s explore where computer science and technology play a key role beyond the classroom.

1. Daily use of the Internet and social media

Every day, millions of people around the world use the internet—checking news, communicating via social media, or watching videos. All of this relies on tools and systems created through computer science. Programming websites, mobile applications, as well as managing servers and data, are the work of IT professionals. Used wisely and in moderation, technology fosters development and changes the way we see the world.

Everyday example: When you search for something on Google or post on Instagram, you’re using IT technologies. Search engines, content management systems, and even algorithms that select content on social media are the fruits of programmers’ and data engineers’ labor.

Why isn’t the Internet pure evil?

As mentioned, it should be used wisely and in moderation. But let’s recall the days of traveling with paper maps in the rain. Think about both car and public transport journeys. Would we want to go back to those days without online maps (especially abroad) or apps that guide us from point A to point B? Some might say yes, but in general, the world seems simpler with these tools, saving us time—an increasingly scarce resource.

2. Artificial intelligence and automation

Artificial intelligence (AI) is one of the fastest-growing fields in computer science. We use it daily, often unknowingly—voice assistants like Siri or Google Assistant, recommendation systems on Netflix or Spotify, and even smart home devices are examples of AI applications. AI automates many tasks, making our lives easier.

Everyday example: When you use navigation on your phone, AI analyzes traffic data to suggest the shortest route. In smart homes, automated systems manage lighting or heating, adjusting to our needs.

3. Online shopping and e-banking

In the era of online shopping and digital payments, computer science plays a key role in ensuring safety and convenience. Payment systems, data encryption, and even e-commerce platforms are created by IT professionals to allow shopping from the comfort of your home.

Everyday example: When you shop online, you rely on security systems that encrypt your data. When you pay by card or use a banking app, technology ensures your transactions are fast and secure.

4. Education and e-learning

In recent years, education has undergone dynamic changes, and computer science has had a significant impact. E-learning platforms like Microsoft Teams, Google Classroom, or Moodle enable remote learning. Students and teachers can collaborate, share materials, and participate in lessons regardless of location.

Everyday example: During the lockdown, most schools moved online, and students used platforms for remote learning. Computer science made it possible to continue education in difficult conditions, creating new opportunities and tools for learning.

5. Healthcare and medicine

Technology plays a crucial role in healthcare. Patient data management systems, diagnostic tools, and even surgical robots are the work of IT professionals. This enables doctors to treat patients more quickly and effectively.

Everyday example: When you visit a doctor, your test results are often stored and analyzed using specialized IT systems. Technologies like telemedicine allow remote consultations with doctors, which is particularly useful for people living in remote areas. Many radiological images or ultrasounds are analyzed by AI to speed up the early detection of cancer.

Computer science as the future

Understanding how computer science works opens up enormous opportunities. It’s not just about programming but also logical thinking, problem-solving, and a creative approach to technology. Teachers should inspire students to explore this field, and parents should support their children in developing a passion for new technologies.

Computer science is not just a school subject but also the key to understanding and navigating the modern world.
