Operating System Fundamentals for Beginners

Operating System Fundamentals for Beginners, Introduction to Operating Systems, Complete course for Beginners.

Hello everyone, welcome to the first lecture in the course Operating system.  So operating system is very important as far computer science is concerned. and also electronic students you may have this subject in your course. This subject consists of theory so we will see what the subject means and what we can learn from the subject.  so First of all it is just an introduction to the Operating system and we will see what this Operating system means and what are the functions of the operating system, what are the types of the operating system, its goals, and different characteristics we will try to get the brief idea of this subject.

Moreover, I will discuss the file systems, their various concepts and make the students familiar with the different techniques of file allocation and access methods.

Then I am going to talk about the various issues of CPU scheduling plus my students will get to know the in-depth knowledge of the types of schedulers.

My students, you will learn about disk scheduling and will get familiar with the characteristics of the disk that affect the performance of the disk scheduling algorithms and the know-how for memory management.

Last but not least in my course my students will get acquainted with the

problem of deadlocks. In this topic, we characterize the problem of deadlocks

and discuss policies, which an Operating system can use to ensure their absence.

Following the course of the conceptual evolution of operating systems, we have identified the main characteristics of the program execution & development environments provided by the bare machine, serial processing, including batch & multiprogramming. On the basis of their attributes & design objectives, different types of operating systems were defined & characterized with respect to scheduling & management of memory, devices, & files.

Alright, so let’s get started.
