The round plastic or metal pegs that separate the motherboard from the bottom of the case are known as standoffs. These standoffs are essential for preventing the motherboard from making direct contact with the case.
Step-by-step explanation:
The round plastic or metal pegs that separate the motherboard from the bottom of the case are known as standoffs. These standoffs are essential for preventing the motherboard from making direct contact with the case, which could cause short circuits or damage to the components.
Standoffs are typically made of brass or plastic and are threaded on one end to screw into the case, while the other end has a round or hexagonal shape to hold the motherboard securely in place.
Standoffs serve to provide insulation and prevent the motherboard from touching the metal surface of the case, ensuring proper grounding and preventing electrical interference.
