Computer science is a vast and exciting field that touches almost every part of modern life. From experience working in Software industry, here's a breakdown of the major areas within computer science that can help guide you:
Software Engineering: This is where you'll spend time building applications, systems, and platforms. Whether it's creating mobile apps, web services, or large-scale distributed systems, this area is all about writing code, solving problems, and making software reliable and scalable. Popular languages include Python, Java, C++, and more.
Algorithms and Data Structures: At its core, computer science is about problem-solving, and this area is critical. Whether you’re optimizing code for performance or handling large datasets, algorithms and data structures help you design efficient solutions. Mastering things like trees, graphs, dynamic programming, and sorting algorithms will be essential as you advance.
Artificial Intelligence (AI) and Machine Learning (ML): These fields are growing rapidly, and you'll find applications everywhere, from recommendation systems to autonomous vehicles. AI/ML involves teaching computers to learn from data, adapt, and make decisions. At Google, we apply AI to everything from search algorithms to smart assistants.
Cybersecurity: Keeping systems secure is a top priority. This involves everything from encryption and secure coding practices to threat detection and mitigation. Security is everyone’s responsibility, especially when working on large-scale systems that handle sensitive data.
Databases and Big Data: Data drives everything, from small apps to global tech companies like Google. Learning how to design, manage, and query databases (SQL and NoSQL) is a key skill, especially as more data gets generated every day.
Networking: The internet connects everything, so understanding how data moves across networks is essential. Whether you're working with cloud services or building the next-gen internet protocol, this area covers everything from basic network setup to complex routing algorithms.
Operating Systems and Systems Programming: To really understand how computers work, it's important to dive into operating systems. Understanding how memory management, process scheduling, and system calls work will give you a deeper appreciation for how software interacts with hardware.
Computer Graphics: If you're into gaming, simulations, or any form of visual design, this is the field for you. From 3D modeling to rendering algorithms, computer graphics bring the digital world to life.
Theoretical Computer Science: This is where computer science meets math. Topics like computational complexity, automata theory, and cryptography fall under this umbrella. While it’s not always directly applied in day-to-day engineering, it’s foundational knowledge that helps shape the way we think about computing.
One thing to remember is that computer science is constantly evolving. The technology we use today will look different in a few years, and that’s what makes this field so exciting. Keep learning, be curious, and don’t be afraid to dive into new areas — it’s how you grow and stay ahead.
Whether you're interested in building software at scale, exploring AI, or working on cutting-edge technology, computer science offers limitless possibilities.

Hi Ibrahim! Computer Science is a wonderful field. It allows you to get a deeper understanding of the computers and technology we all use on a daily basis.
In college, you would learn a lot from this field about how the base of technology works. You first learn about the core components, how memory and processors work and things like binary. You then move on to assembly language and how languages like C and compilers work. The likely target is to learn a more high level programming language so you can create software like web and mobile applications. It's important to note that while it can be very useful to understand these core functionalities of computing, you don't need to full understand them to learn to code and create software. Many successful software engineers and developers focus on higher-level languages and frameworks (like Python, JavaScript, etc.) without a deep dive into low-level systems. For these areas, jumping into coding directly with languages like Python is very approachable and fulfilling. If that is what you're after, you can look into learning a programming language like Python, and see if you can build things that you find interesting. There are many resources online to get started like Codecademy or even just free Youtube videos.
If the core of computer science really interests you, you can actually find computer science lectures from schools like Stanford on Youtube. This could give you some insight into what classes might be like and if you would find the field truly interesting.
Look into Stanford CS courses on Youtube
Use resources like Codecademy or youtube to learn a programming language like Python
