This course is designed to give you a complete understanding of how computers and modern IT systems work—from the lowest level of binary data to the global infrastructure of the internet.

Instead of memorizing definitions, you will develop a mental model of how hardware, software, operating systems, and networks interact to power real-world applications. This knowledge is critical for anyone pursuing software engineering, DevOps, cybersecurity, or any technical career.

We begin with the fundamentals of computers, including how data is represented using binary and how hardware components such as CPUs, memory, and storage operate. You will then learn how operating systems manage processes, files, and permissions, and how to interact with systems using the command line.

The course also covers networking and internet fundamentals, helping you understand how devices communicate, how websites are accessed, and how modern cloud systems are structured. You will gain practical skills such as navigating file systems, managing software packages, and understanding system-level operations.

By the end of this course, you will have a strong technical foundation that makes learning advanced topics like programming, system design, and cloud computing much easier.
