OPERATING SYSTEMS

Course Code: BTE 405 Credit Units: 03

Course Objective:Operating Systems serve as one of the most important courses for undergraduate students, since it provides the students with a new s

to envision every computerized systems especially general purpose computers. Therefore, the students are supposed to study, practice

discuss on the major fields discussed in the course to ensure the success of the education process. The outcome of this course implic

and explicitly affects the abilities the students to understand, analyze and overcome the challenges they face with in the other courses

the real world.
