Information Technology, or IT, is a vast and continuously evolving field that encompasses hardware, software, networks, databases, and so much more. In today’s digital age, it has become an essential part of our lives, from using smartphones to perform everyday tasks to relying on complex systems for business operations.

However, with its ever-growing complexity and constant changes in technology, IT can be intimidating and overwhelming, especially for those who don’t have a technical background. If you find yourself in this situation, don’t worry; you are not alone.

This document will provide some guidance on where to start when you don’t know anything about IT. It will also give an overview of the general topics and concepts that make up the world of IT, helping you gain a better understanding of this vast field.

Understanding IT

Before diving into specific topics and concepts, it’s essential to have a general understanding of what IT is and its role in our daily lives. As mentioned earlier, IT encompasses various components that work together to manage information effectively. It involves the use of technology to store, process, retrieve, and transmit data or information.

IT is not just limited to computers and devices; it also includes the management of networks, databases, and software applications. The primary goal of IT is to improve efficiency, productivity, and communication within an organization or individual.

Let’s dive into some key topics that make up this field. These topics are interconnected and continuously evolving, so it’s crucial to have a basic understanding of each.

Computer Hardware

Computer hardware refers to the physical components of a computer system, such as the central processing unit (CPU), random access memory (RAM), hard drive, and peripherals like monitors, keyboards, and mice. Understanding computer hardware is essential as it forms the foundation of any IT system.


Software is a set of instructions or programs that tell a computer what to do. It includes operating systems, applications, and programming languages. Without software, hardware would be useless. Understanding different types of software and their functions is essential in navigating the world of IT.

Computer Networking

Computer networking involves connecting multiple devices, such as computers, printers, and servers, to share data and resources. Understanding how networks operate is crucial in today’s digital age when most organizations rely on interconnected systems for their day-to-day operations.

Database Management

As the amount of data generated continues to grow exponentially, the need for database management has become more critical than ever. Database management involves organizing, storing, and retrieving data efficiently. It’s a crucial aspect of IT as it enables organizations to make informed decisions based on their data.


With technology comes the risk of cyber threats such as hacking, phishing, and malware attacks. Cybersecurity is the practice of protecting computer systems and networks from these threats. It’s a rapidly evolving field, and understanding the basics of cybersecurity is vital in today’s digital landscape.

IT may seem like a daunting field to navigate, but with the right guidance and foundational knowledge, anyone can gain a better understanding of it. This document has provided an overview of where to start when you don’t know anything about IT and introduced some key topics that make up this vast field. With continuous learning and exploration, you can expand your knowledge and become more comfortable with technology and its constantly evolving landscape. So, if you are someone who wants to learn more about IT, use this document as a starting point and continue exploring the different topics and concepts that make up this ever-evolving field.
