Foundations of Computer Science and Systems Design

The Complete CS Foundation — From Transistors to Transformers

Foundations of Computer Science & Systems Design is a first-principles, Python-integrated technical textbook that takes B.Tech, BS/MS, BSe, B.E., BCA, and diploma engineering students on a complete journey — from the physics of transistors and Boolean algebra, through computer architecture and operating systems, to machine learning, neural networks, and cloud computing. Eighteen chapters. Six structured parts. One coherent path.

What You Will Learn

• Boolean algebra, logic gates, Karnaugh map minimisation


• Number systems: binary, octal, hexadecimal, and BCD arithmetic


• Combinational circuit design — adders, decoders, multiplexers, ALUs


• Sequential circuits — flip-flops, registers, counters, finite state machines


• CPU architecture, instruction sets, pipelining, and memory hierarchy


• Operating systems: process scheduling, memory management, file systems


• Python programming from fundamentals to recursion and OOP


• Data structures and algorithms with Big-O complexity analysis


• NumPy, Pandas, and Python for data science and analytics


• Machine learning: regression, classification, decision trees, SVMs


• Neural networks, deep learning, and Transformer architectures


• Cloud computing infrastructure, virtualisation, and green IT
