📚 What You'll Learn in This Video:
Operating System Services:

Discover the essential services provided by operating systems, including program execution, I/O operations, file-system manipulation, communication, error detection, resource allocation, and more.
Learn how these services play a crucial role in the functioning and management of computer systems.
System Calls:

Understand what system calls are and why they are vital for the interaction between a running program and the operating system.
We'll explore different types of system calls, such as process control, file management, device management, information maintenance, and communications.
System Programs:

Get to know the various system programs that serve as interfaces between the system call interface and the user, such as file manipulation, status information, file modification, programming-language support, program loading and execution, and communications.
Operating System Design and Implementation:

Gain insights into the design and implementation process of operating systems.
We'll discuss the various design goals, from user goals like convenience and ease of use, to system goals like efficiency and reliability.
Operating System Structure:

Delve into different OS structures, including simple structure, layered approach, microkernels, and modules.
We'll compare and contrast these structures, highlighting their advantages and disadvantages.
Virtual Machines:

Learn about virtual machines and how they allow multiple OS environments to run simultaneously on a single physical machine.
We'll explore the concept of hypervisors and the difference between Type 1 and Type 2 hypervisors.
Operating System Generation:

Explore the process of OS generation, including the role of system programs and the process of building an operating system from source code.
System Boot:

Understand the booting process, from the boot loader to the initialization of the operating system.
We'll discuss how the OS is loaded into memory and the steps involved in starting the system.
