You’ll learn about different types of graphs, such as directed and undirected graphs, and algorithms for traversing graphs. Combinatorics is the study of counting and arranging objects. You’ll learn about permutations, combinations, and the binomial theorem. Discrete mathematics might seem abstract at times, but it provides the mathematical foundation for many computer science concepts. It's like the language that computer scientists use to communicate ideas precisely and unambiguously. Don't underestimate the importance of this course! A solid understanding of discrete math will make it much easier to grasp more advanced topics later on.

Computer Architecture and Organization

Ever wondered what's going on under the hood of your computer? Computer Architecture and Organization will give you a peek inside. You’ll learn about the different components of a computer system, such as the CPU, memory, and input/output devices. You’ll learn how these components work together to execute instructions. Expect to study topics like instruction set architecture, memory management, and cache design. You'll also learn about the different types of buses and how they are used to connect the different components of the system. This course often involves a fair amount of low-level programming, such as assembly language. Assembly language is a low-level programming language that is close to the machine code that the computer actually executes. Learning assembly language can give you a deeper understanding of how computers work at the hardware level. Computer architecture and organization is a fascinating subject that will give you a newfound appreciation for the complexity and ingenuity of modern computer systems. It's like taking apart a clock to see how all the gears and springs work together to keep time.

Operating Systems

Operating Systems are the software that manages the hardware resources of a computer system and provides services to applications. In this course, you’ll learn about the different types of operating systems, such as Windows, macOS, and Linux. You’ll also learn about the different components of an operating system, such as the kernel, the file system, and the process manager. Expect to study topics like process scheduling, memory management, and file system design. You'll also learn about concurrency and how to handle multiple processes running simultaneously. This course often involves a fair amount of systems programming, such as writing device drivers or implementing system calls. Systems programming is a specialized area of programming that requires a deep understanding of the operating system and the underlying hardware. Operating systems is a crucial subject for any computer scientist. It's like learning how the city works – the roads, the utilities, and the services that make it all function smoothly. A solid understanding of operating systems will make you a better programmer and a more effective problem solver.

Elective Subjects

Beyond the core subjects, you'll also have the opportunity to choose elective courses that align with your interests. This is where you can start to specialize in a particular area of computer science. Here are a few popular elective subjects:
