Question

which of the following protects a computer system from electrostatic discharge while handling computer components?
○ post card
○ anti-static wrist strap
○ power supply tester
○ static shielding bag

Explanation:

To determine which option protects a computer system from electrostatic discharge (ESD) while handling components, we analyze each choice:

• POST card: Used for power - on self - test troubleshooting, not ESD protection.
• Anti - static wrist strap: Worn by technicians to ground themselves, preventing ESD from damaging components during handling.
• Power supply tester: Checks power supply functionality, not for ESD protection.
• Static shielding bag: Used for storing/transporting components, not during active handling.

Answer:

B. Anti - static wrist strap
