COMPUTER ARCHITECTURE AND HARDWARE MAINTENANCE
RATIONALE
The subject provides the students with the knowledge of detailed organization of currently available personal computers in order to understand their functioning .The students will also get familiar with Architecture of multi processor systems.
LEARNING OUTCOMES
After undergoing the subject, students will be able to:
- use CPU, register and stack.
- compare micro programmed and hardwired control.
- compare RISC and CISC architecture.
- understand memory hierarchy and memory types.
- explain the function of BIOS.
- illustrate multi processor systems.
- set-up, diagnose problems troubleshoot & Maintained the computer components.

INSTRUCTIONAL STRATEGY
Since the subject is theoretical one, the practical aspects should be taught along with the theory instruction. The students should be given quiz tests and asked to give seminars on small topics. There is sufficient time in the subject and the students can be taken to
laboratory for demonstration.
MEANS OF ASSESSMENT
− Assignments and quiz/class tests, mid-term and end-term written tests
− Viva-voce
