  Dear Students,
  

  Welcome to Operating System & Lab (CSE 323/324). I am Raja Tariqul Hasan Tusher, Senior Lecturer, Department of Computer Science and Engineering (CSE) and I am your instructor in this course. In addition to welcoming you to the course, I would like to say "Online courses provide a different way to study and place different skills from students". I will provide you the necessary support during the course to successfully complete this course.

  Let's move together with your Love & Cooperation.

    Course Rationale

    Operating systems are central to computing activities. An operating system is a program that acts as an intermediary between a user of a computer and the computer hardware. Two primary aims of an operating system are to manage resources (e.g. CPU time, memory) and to control users and software. Operating system design goals are often contradictory and vary depending of user, software, and hardware criteria. This course describes the fundamental concepts behind operating systems, and examines the ways that design goals can be achieved.
