OSI vs TCP/IP 🌐

The OSI model explains how networking works conceptually.

The TCP/IP model is what actually powers the internet.

1. Physical / Network Interface
→ Handles physical data transmission

2. Data Link / Internet Access
→ Identifies devices using MAC addresses

3. Network / Internet Layer
→ Routes packets across networks using IP

4. Transport Layer
→ Enables reliable communication with TCP/UDP

5. Application Layer
→ Connects applications like browsers & servers

OSI has 7 layers.
TCP/IP simplifies them into 4 layers.
