1. Meaning of Networking 🏷️

Networking is the process of connecting two or more computers or devices so they can communicate and share resources like files, internet, printers, and applications.

  • In simple words: “Connecting devices to talk to each other.” 🖥️↔️💻

  • Example: Your laptop connects to your home Wi-Fi to access the internet or share files with another PC. 📡

2. Concept of Networking 💡

Networking involves several key ideas:

  1. Devices (Nodes): Any computer, printer, smartphone, or server connected in a network. 🖥️📱

  2. Communication Medium: The physical or wireless link (Ethernet cables, Wi-Fi signals) connecting devices. 🔗

  3. Protocols: Rules that devices follow to communicate, e.g., TCP/IP. 📜

  4. Sharing Resources: Enables access to internet, printers, storage, and applications. 🗂️🖨️

  5. Network Types:

    • LAN (Local Area Network): Small area like home/office 🏠

    • WAN (Wide Area Network): Large area like the internet 🌍

    • PAN (Personal Area Network): Personal devices connected nearby 🔵

  6. IP Addressing & DNS: Each device has a unique identifier (IP) to communicate, and DNS translates website names to IP addresses. 🏷️➡️🌐

3. Why Networking is Important ⚡

  • Resource Sharing: Multiple devices can use the same printer, storage, or internet. 🖨️💾

  • Communication: Enables emails, chat, video calls, and collaboration. 📧💬

  • Cost-Effective: Reduces the need for duplicate resources. 💰

  • Data Management: Centralized storage and backup are easier in a network. 💾

4. Practical Example 🖧

Imagine a school computer lab:

  • 20 computers are connected through a LAN.

  • They share one internet connection, one printer, and can transfer files among themselves.

  • Teacher can monitor all computers from the server. 👩‍🏫

💡 Summary: Networking is all about connecting devices to communicate, share resources, and work efficiently, whether it’s in your home, office, or across the globe. 🌐💻🖥️

Internet configuration and troubleshooting

-
  1. Internet Configuration Basics ⚡ A. Connecting to Internet Via Cable/DSL: Connect modem → router → PC (Ethernet cable) 🔌 Via Wi-Fi: Connect PC/laptop to wireless SSID 📶 Mobile Hotspot: Use smartphone to share cellular data 📱 B. IP Configuration 🏷️ Automatic (DHCP): Router assigns IP, subnet mask, gateway automatically ✅ Manual (Static IP): You assign: IP Address: Unique identifier (e.g., 192.168.1.10) Subnet Mask: Usually 255.255.255.0 Default Gateway: Router IP (e.g., 192.168.1.1) DNS Server: IP to resolve domain names (e.g., 8.8.8.8 for Google DNS) Windows: Control Panel → Network & Sharing Center → Adapter Settings → IPv4 Properties Linux: sudo ip addr add 192 .168.1.10/24 dev eth0 sudo ip route add default via 192 .168.1.1 2. Internet Troubleshooting Steps 🔧 Step 1: Check Physical Connection 🔌 Ethernet cable connected? Wi-Fi enabled and connected to correct SSID? Modem/router powered on? Ste...
