Computer networking is the foundation of modern digital communication. Whether you're connecting two devices or managing hundreds in a business, understanding how networks operate is crucial. Here, we’ll cover key concepts:
1. What is a Network?
A network is a group of interconnected devices that communicate and share resources like files, internet, and printers. Networks can be as small as two devices or span across the globe.
2. LAN vs WAN
LAN (Local Area Network) connects devices within a small area like a home or office. WAN (Wide Area Network) spans large geographical regions — like the internet. Learn more about LAN vs WAN →
3. Routers and Switches
Routers connect different networks and handle internet traffic, while switches connect multiple devices within a LAN and manage internal data traffic. Read more on Routers & Switches →
4. IP Addressing
Every device on a network gets an IP address—a unique identifier for communication. There are static and dynamic IPs. Understand IP Addressing →
5. Wired vs Wireless Networks
Wired networks use cables like Ethernet for fast, secure connections. Wireless networks (Wi-Fi) offer mobility and convenience. Each has its own advantages. Compare Wired vs Wireless →
6. Network Troubleshooting
Common network issues include slow speed, disconnections, or IP conflicts. Tools like ping, traceroute, and checking cables can help solve problems. See basic troubleshooting tips →
7. Structured Cabling & PABX
Structured cabling ensures neat and reliable connectivity, especially in offices. PABX systems manage internal/external calls efficiently. Explore structured cabling and PABX →
