Welcome to 'Introduction to Operating Systems' course ! This lecture introduces the concept of processes, building upon the understanding of programs. It explains how a program transforms into a process when loaded into memory for execution, highlighting the key components of a process, including the text section, data section, heap, stack, and state. The lecture then describes the concept of a memory map, illustrating how different segments of a process are organized in memory. It also discusses the role of system calls in enabling processes to request services from the operating system, such as file access. Finally, the lecture touches upon different operating system structures, comparing monolithic kernels and microkernels.
