Week 1: Introduction to Information Technology

Information Technology (IT) is more than just computers—it is the foundation of how we live, work, and communicate today. IT refers to the use of systems, networks, software, and devices to manage and process information. From payroll systems at work to the apps on our phones, IT surrounds us in nearly every aspect of life.

For me, IT connects closely with both my career and education. In my current role at ADP, I work in payroll support, where technology allows businesses to operate efficiently and employees to get paid accurately. Before this, I worked at UPS as a Customs Brokerage Representative and at Apple via Kelly Services, where I focused on technical problem-solving through chat and email support. These experiences showed me how powerful IT is in helping businesses solve problems and stay connected.

Looking at the bigger picture, IT shapes society by making communication faster, businesses more productive, and personal lives more convenient. It is also a growing career field with endless opportunities, which motivates me as I pursue my bachelor’s degree in Cyber and Data Security.

Week 2: Understanding Hardware and Software

One of the most important lessons I’ve learned is the difference between hardware and software. Hardware is the physical part of a computer, like the motherboard, memory, or hard drive. Software is the programs and applications that run on the hardware, like Microsoft Office, Zoom, or web browsers.

In my IT coursework, I’ve had hands-on experience with labs that explored motherboards, installing network adapters, and connecting different components. These exercises helped me understand how all parts of a computer work together to make it functional. For example, without a properly installed network adapter, a computer cannot connect to the internet—something most of us rely on every day.

This lesson connects directly to real-world IT careers. Whether you are in technical support or cybersecurity, knowing how hardware and software work together is essential for diagnosing problems, upgrading systems, and ensuring security. Understanding these basics has given me more confidence as I build toward advanced IT concepts.

Week 3: Databases and Networking

Data drives everything. Every website we visit, every app we use, and every transaction we make creates and stores data. Databases organize this information in ways that make it accessible and useful.

Recently, I worked with Microsoft Access to run queries and explore how databases filter and analyze information. This exercise showed me how businesses track inventory, monitor customer activity, and improve decision-making. It was fascinating to see how a simple query could return specific results out of thousands of entries.

Networking is equally important. Networks connect computers and devices, allowing data to flow securely between them. Without networking, we wouldn’t have email, cloud storage, or even social media. As technology evolves, networking skills are becoming more essential, especially in careers like technical support, system administration, and cybersecurity.

Together, databases and networking form the backbone of IT. They ensure that information is stored safely and shared efficiently—skills I know I’ll use as I move forward in both school and my career.

Week 4: Ethics and Security in IT

Technology is powerful, but it also comes with responsibility. Ethics in IT is about using technology in ways that are honest, fair, and respectful of privacy. With cyber threats constantly increasing, security and ethics are closely linked.

One case study that stood out to me involved the moral question of whether it is ever right to break a rule (or law) if it means protecting someone. This connects to cybersecurity, where ethical hackers may test systems to identify weaknesses before criminals exploit them. While their actions might look like “breaking in,” they actually serve a greater good by improving security.

As I pursue my degree in Cyber and Data Security, I see ethics as central to my future career. Protecting sensitive data—whether it’s financial records, healthcare information, or personal communications—is not just about following laws; it’s about doing what is right.

Strong ethics in IT builds trust between companies, customers, and communities. For me, this means striving to be both skilled and responsible in every aspect of my IT career.
