Which device is commonly used to connect computers within a LAN?
Switch
A switch is a device that connects multiple computers within a LAN (Local Area Network). It forwards data packets between devices based on their MAC addresses, allowing them to communicate efficiently.
Switch
✅ Correct Answer: Switch
Explanation:
A switch is commonly used to connect multiple computers within a Local Area Network (LAN).
It efficiently forwards data only to the device it's intended for, improving network performance.
Router connects different networks (e.g., LAN to internet)
Modem connects a network to the internet
Repeater boosts signal strength over long distances
Switch
The correct answer is:
✅ Switch
Explanation:
Switch: The primary device used to connect multiple computers within a Local Area Network (LAN). It efficiently directs data packets to the correct devices using MAC addresses.
Example: Connects PCs in an office/school.
Why Not Other Options?
Modem: Converts digital signals to analog (for internet access, not LAN connectivity).
Router: Connects multiple networks (e.g., LAN to WAN/internet), not devices within a single LAN.
Repeater: Extends network range by boosting signals (doesn’t manage connections).
Key Difference:
Switch → LAN-only, hardware-based forwarding.
Router → Inter-network, IP-based routing.
Answer: Switch (Option 3) ✅
