Notes:

Source:

This course contains of fundamental concepts of different microprocessors, assembly language programming, basic I/O Interfaces and Interrupt operations.

To introduce the operation, programming, and application of microprocessor. To teach students how the various components of the computer works and their inter relationship from the processor to other units.

Students will have to complete the assigned practical work throughout the semester and Practical examination will be conducted at the end of academic semester. The practical exam will be graded on the basis of the following marking scheme: In-Semester Evaluation 25%, Final Exam Written 50%, Final Exam Oral 25%.

This syllabus follows the official CSIT curriculum of Far Western University. In case of any doubt or revision, the university's published syllabus shall be considered authoritative. https://cdc.fwu.edu.np/faculties.html
