On my first day in Introduction to Computers, the lecturer welcomed us and explained that every computer starts with Input Devices, then processing, then Output Devices.

We discussed what makes a computer work: Hardware is the physical parts, and Software is the programs that tell the hardware what to do.

The demonstration focused on the CPU, RAM, and Secondary Storage. The CPU executes instructions, RAM is fast temporary memory, and secondary storage keeps files even when the computer is powered off.

Next, we learned the difference between Data and Information. Data are raw facts, and information is what we get after processing data into a useful form.

We also covered digital representation: computers store values using Bit and Byte, and the Binary number system.

In the practical session, we wrote our first Algorithm on paper, then turned it into a simple program using a Programming Language.

The lecturer explained that the Operating System manages hardware resources and runs programs, while an Application is software designed for a specific task (like a browser or a document editor).

For the web part of the lecture, we opened the course Website using a Browser. We talked about how the Internet connects networks, including a LAN on campus.

We finished by learning that devices use an IP Address to identify each other on a Network. Finally, we covered basic Security: keep your Password safe, understand Encryption, and use Debugging when software behaves unexpectedly.
