👉Subscribe to our new channel: null In this video, Varun sir has discussed Physical layer of computer networks. Physical layer is the lowest or last layer of the OSI model. It is responsible for the physical transmission of data over the network. It deals with the actual hardware and physical components that enable communication between devices. 0:00 - Introduction 1:52 - Cables and Connectors 4:13 - Topology 5:37 - Hardware (Repeaters, Hubs) 6:34 - Transmission mode 7:04 - Multiplexing 8:32 - Encoding ►Repeaters in Computer Networks: https://www.youtube.com/watch?v=mf4bRP_puNQ ►Hub in Computer Networks https://www.youtube.com/watch?v=3N5a9cHYzCM ►Computer Networks (Complete Playlist):    • Computer Networks (Complete Playlist)   Other subject-wise playlist Links: -------------------------------------------------------------------------------------------------------------------------------------- ►Design and Analysis of algorithms (DAA):    • Design and Analysis of algorithms (DAA)   ►Database Management System:    • DBMS (Database Management system) Com...   ► Theory of Computation    • TOC(Theory of Computation)   ►Artificial Intelligence:    • Artificial Intelligence (Complete Pla...   ►Computer Architecture:    • Computer Organization and Architectur...   ►Operating System:    • Operating System (Complete Playlist)   ►Structured Query Language (SQL):    • Structured Query Language (SQL)   ►Discrete Mathematics:    • Discrete Mathematics   ►Compiler Design:    • Compiler Design (Complete Playlist)   ►Number System:    • Number system   ►Cloud Computing & BIG Data:    • Cloud Computing & BIG Data   ►Software Engineering:    • Software Engineering   ►Data Structure:    • Data Structure   ►Graph Theory:    • Graph Theory   ►Programming in C:    • C Programming   ►Digital Logic:    • Digital Logic (Complete Playlist)   --------------------------------------------------------------------------------------------------------------------------------------- Our social media Links: ► Subscribe to us on YouTube: null ►Subscribe to our new channel: null ► Like our page on Facebook: https://www.facebook.com/gatesmashers ► Follow us on Instagram: https://www.instagram.com/gate.smashers ► Follow us on Instagram: https://www.instagram.com/varunainashots ► Follow us on Telegram: https://t.me/gatesmashersofficial ► Follow us on Threads: https://www.threads.net/@gate.smashers -------------------------------------------------------------------------------------------------------------------------------------- ►For Any Query, Suggestion or notes contribution: Email us at: gatesmashers2018@gmail.com #ComputerNetworksbyGateSmashers #ComputerNetwork #physicalLayer
