Introduction
If you’re asking “what is information technology?“ you’re not alone. This fundamental question drives millions of searches as our world becomes increasingly digital. This definitive guide breaks down exactly what information technology means today, why it matters more than ever, and how it impacts every aspect of modern life.

What Is Information Technology?
Information technology (IT) is the use of computers, networking, storage, and other physical devices and infrastructure to create, process, store, secure, and exchange all forms of electronic data. In simple terms, information technology is how we handle information using digital systems.
When people ask “what is information technology?” they often think of tech support. But modern information technology is far broader—it’s the backbone of banking, healthcare, education, and entertainment.
The 5 Core Components of Information Technology
Understanding what information technology truly encompasses requires looking at its essential parts:
- Hardware – The physical equipment: servers, computers, routers, and devices
- Software – The programs and operating systems that run on hardware
- Networking – Systems that connect devices to share data and resources
- Data Management – Systems that organize, store, and protect information
- Cybersecurity – Protection of all digital assets from threats
These components work together to form complete information technology systems.
