š Layer 3: Network Layer (OSI Model)
How do data packets find their way across global networks? Through the Network Layer.
Here are the key points:
š¹ 1. What is it?
The 3rd layer of the OSI model. It handles logical addressing and routing across different networks.
š¹ 2. Core Functions
IP Addressing: Uses unique IP Addresses (IPv4/IPv6) to globally identify devices.
Routing: Determines the fastest and most secure path for data packets.
Packetizing: Breaks down large data into smaller packets with IP headers.
š¹ 3. Hardware & Protocols
Hardware: Routers connect different networks and forward packets.
Protocols: IP, ICMP, and routing protocols (OSPF, BGP).
š Just like Google Maps finds the best route for your car, the Network Layer finds the optimal route for your data!
š Do you know your device's IP address? Let me know!
