📦 Packets vs Frames

📘 Packets (Network Layer - Layer 3)

  1. Contain logical addressing information such as IP addresses (source & destination).

  2. Used for routing data between different networks.

  3. Created at the Network Layer of the OSI model.

  4. Protocols like IP (Internet Protocol) handle packet creation and delivery.

📗 Frames (Data Link Layer - Layer 2)

  1. Contain physical addressing information such as MAC addresses.

  2. Used for data transfer within the same local network (LAN).

  3. Created at the Data Link Layer of the OSI model.

  4. Protocols like Ethernet or Wi-Fi (802.11) define frame structure.

🖥️ Private IP vs Public IP Address

  🖥️ Private IP vs Public IP Address 🧠 Definition: Private IP Address: Used inside a private network (LAN) — identifies devices like PCs, printers, and routers within a local area. Example: 192.168.1.10 Public IP Address: Used on the Internet — identifies your network or device globally so it can communicate with other networks. Example: 8.8.8.8 🔹 Key Differences Feature Private IP Address Public IP Address Scope Used within local/private networks Used on the Internet (global scope) Uniqueness Can be reused in different networks Must be unique worldwide Assigned by Network Administrator or Router (DHCP) Internet Service Provider (ISP) Accessibility Not reachable from the Internet Reachable over the Internet Security More secure, hidden from external access Less secure, visible on the Internet Example Ranges 10.0.0.0 – 10.255.255.255 172.16.0.0 – 172.31.255.255 192.168.0.0 – 192.168.255.255 1.0.0.0 – 223.255.255.255 (except private ranges) 💡 Quick Example...
