FAQ

Information Technology (IT) is everything involved in using computers and digital systems to store, process, send, and secure information. Think of it as the technology behind how data travels and how devices communicate.

Here’s a simple breakdown of how IT works — in 5 major components:

---

✅ 1️⃣ Hardware – The Physical Machines

These are the devices that handle data:

• Computers, laptops

• Servers (powerful computers that store and deliver data)

• Smartphones

• Network devices (routers, switches)

They are the body of IT.

---

✅ 2️⃣ Software – The Programs & Apps

Software tells the hardware what to do:

• Operating systems (Windows, Linux, macOS, Android)

• Applications (browsers, games, business apps)

• Databases and management tools

Software is the brain of IT.

---

✅ 3️⃣ Data – The Information Itself

Data is the reason IT exists:

• Text, files, images, videos, records, transactions

• Stored in databases or the cloud

• Processed to make decisions

Data is the knowledge that must be protected and managed.

---

✅ 4️⃣ Networking – The Connection Between Devices

Networking allows information to move:

• Internet

• Wi-Fi

• Mobile networks (4G/5G)

• Local networks (LAN)

Networking is the nervous system that lets devices communicate.

---

✅ 5️⃣ Security – Protection from Threats

IT security ensures:

• Data is safe from hackers

• Systems run without disruption

• Only trusted users have access

Security is the shield of IT.

🚀 Putting It All Together

Component	What It Does	Example
Hardware	Stores and runs info	Laptop, server
Software	Processes info	Word, Facebook app
Data	Information being processed	Photos, financial records
Networking	Sends info between systems	Internet, Wi-Fi
Security	Protects data and systems	Passwords, firewalls

A Real-life Example 🏦

You buy a product online:

1. You use a device (hardware)

2. Through a browser app (software)

3. Your order details become data

4. Sent through the internet (networking)

5. Protected using encryption (security)

IT makes the transaction fast, safe, and possible.
