Office hours Availability of the lecturer to the student during the week 7. Course code 8. Teacher's academic profile B.sc certificate Graduated from university of Duhok. College Of scie computer science department in M.sc certificate computer sc department, College of Education University of Xakho in Keywords OS Definition, Types and Modes of Oss, OS Functions, Memory Management, Process Management, Dead File Management, Types of Famous Oss, Cache Memory Multi-Threading, Parallel Processing. 10. Course overview: This course will help the students to understand about operating system and how it is works as link betw users and hardware. Generally this course will focus on the goals and services of operating system so students will learn the fam types of Oss and it s applications in real life. Furthermore it explains the functions of OS theoretically and practically so every one can understand easy. In additional, the course provides the kinds and manageme also it allows students to know about Os that install on PC like windows XP, Win7, etc. 11. Course objective: The course will provide information for helping and understanding students the roles of OS in managing PC able them to install the reasonable systems on PC and detect faults or error when happen then fix (enhance They will know how format the PC and Install necessary Programs. 12. Student's obligation The student must lecture attention, in terms of attendance. Prepare for exams QIZ. Learn how to write reports on a topic. Students must careful in performing and non-exam cheating. 13. Forms of teaching Each lecture is being represented and demonstrated by power point.

Student learning outcome: Install and manage reasonable OS software according to their properties for example windows7, server, Linux,, etc. And install other programs on PC, Format the PC and reinstalling it, Fix the PC and changes parts of hardware if it necessary. Demonstrate an understanding of the OS functions (memory management, Process management. Distinguish between files types like FAT and NTF and properties oh each one. Talking information about computer organization like processor (CPU), primary and secondary memory and cache memory. 16.
