Lecture 4: Operating System Services & System Calls | GUI, CLI, APIs (Win32, POSIX, Java)

In this Lecture 4 of our Operating Systems series, we explore Operating System Services and System Calls in detail. An Operating System provides essential services that help users and programs interact efficiently with computer hardware. In this lecture, we cover: ✔ User Interface (GUI & CLI) ✔ Program Execution ✔ I/O Operations ✔ File System Manipulation ✔ Communication Between Processes ✔ Error Detection ✔ Resource Allocation (CPU, Memory, Storage) ✔ Accounting ✔ Protection & Security ✔ System Calls and APIs (Win32, POSIX, Java API) We also discuss how system calls act as a bridge between user programs and the operating system, and how APIs simplify system-level programming. This lecture is important for students of BSCS, IT, Software Engineering, and anyone preparing for Operating Systems exams or interviews. 📌 Playlist: Operating Systems Complete Course 📌 Channel: BytePulse Lab 📌 Instructor: Taseer Ullah Don’t forget to Like, Share & Subscribe for upcoming lectures!
