CTEVT diploma  Operating system 2076 and 2075 question paper : 

Here is the Operating system question paper of CTEVT 2076 and 2075 are in this articles. This is the new course of the CTEVT Diploma. Operating system subject is available in fifth semester and This subject give the basic understanding and the feature of the operating system. The main objective of this subject is that:

1. Define operating system.

2. Explain the history and functions of operating system.

3. Describe need and role of operating system.

4. Describe operating system as resource manager and virtual machine.

5. Explain the memory management techniques.

6. Explain the file management techniques.

7. Analyze and compare different scheduling algorithms used by OS.
