What is a Repeater in Networking? | Simple Explanation
A Repeater is a Layer 1 device that helps extend the range of a network.
It:
Receives a weak or distorted signal
Regenerates and amplifies it
Sends it forward as a clean, strong signal
Think of it like a megaphone — it doesn’t change the message, just makes it louder so it can travel farther.
Commonly used in wired and wireless networks to boost connectivity over long distances.
A basic but important concept for CCNA learners and networking beginners.
