Learn and Master C Programming - Software: BIOS, OS and Programs

The lecture covers the basics of operating systems, explaining their role in managing computer resources and providing services for programs. It defines computer programs as sets of instructions written in a language understood by computers, typically in binary format. The lecture also discusses the CPU, its components like the ALU and control unit, and the memory hierarchy, including registers, cache, and main memory. It explains how programs are stored on persistent storage and loaded into RAM for execution. The lecture concludes with a preview of the next topic, focusing on programming languages and the role of C.
