12. Repeaters In CN| OSI Layer 1 Network Devices | Distance Extension & Functions

Welcome back to our Computer Networks series! Today, we are focusing on one of the most fundamental networking devices operating at the Physical Layer (Layer 1 of the OSI Model): The Repeater. If you are preparing for your university semester exams, GATE CSE, or UGC NET, understanding how and why we extend network segments is crucial. We break down exactly how a repeater works, its core functionalities, and clear up the biggest confusion students have: the difference between regenerating a signal and simply amplifying it. 📝 Topics Covered in This Video: What is a Repeater? (Basic definition and need). OSI Model Layer: Why it operates purely at the Physical Layer. Core Functionality: Signal Regeneration (cleaning up attenuated signals). Repeater vs. Amplifier: The critical difference you need to know for exams. Network Extension: How repeaters connect LAN segments to increase physical distance. Key Characteristics: 2-port device, no filtering capability, and no MAC address reading. Important previous year questions for GATE & university exams. ⏳ Timestamps: 0:00 - In This Video #NetworkRepeater #ComputerNetworks #OSIModel #PhysicalLayer #GATECSE #UGCNET #ComputerScience #NetworkingDevices #BTechCSE #SignalRegeneration
