COMPETENCY STATEMENT (S):
To handle & maintain computer systems.
To troubleshoot computer system.
RATIONALE:
Knowledge of Computer and its peripherals is essential for information technology students. Students must aware of specifications, types, varieties and vendors supplying different peripherals of computer systems. Installing and testing of these peripherals will help students to diagnosis the minor hardware problems and to rectify the same immediately. This will increase the confidence of students of handling hardware and software problems simultaneously.
