Gravit Siya is planning to connect 15 office computers using Ethernet Cable. Which one of the following devices should he use for the same?

Correct option is A

The correct answer is (a) Switch.
Explanation:
● A Switch is a networking device that connects multiple devices (computers) on a computer network.
● It uses packet switching to receive and forward data to the specific destination device.
● For 15 computers, a switch with enough ports (e.g., a 16-port or 24-port switch) is the standard solution.
Information Booster:
● Unlike a Hub, a Switch is "intelligent" as it sends data only to the intended recipient.
● Switches operate at the Data Link Layer (Layer 2) of the OSI model.
Additional Knowledge:
● Booster – Used to amplify signals (like Wi-Fi) over a long distance.
● HDMI Splitter – Used to send a single video signal to multiple screens.
● Repeater – Amplifies a signal to prevent it from degrading over long cables.
