Describe the hardware that is used to support the internet

📡 The Core Hardware that Makes the Internet Work

Think of the internet as a giant city. The hardware is like the roads, traffic lights, and buildings that keep everything moving smoothly.

🛠️ 1. Routers & Switches

Routers are the traffic directors that decide which way data packets should travel. Switches are the local traffic lights that connect devices within a single building or campus.

• 📌 Router: Directs traffic between different networks.
• 📌 Switch: Connects devices within the same network.

🔌 2. Cables & Connectors

Just like roads need pavement, data needs cables to travel.

1. 🟢 Ethernet Cable (Cat5e, Cat6): Most common for LAN connections.
2. 🟠 Fiber Optic Cable: Uses light to carry data over long distances at very high speeds.
3. 🟣 Coaxial Cable: Used mainly for cable TV and some broadband.

🏗️ 3. Data Centers & Server Racks

These are the skyscrapers of the internet, housing thousands of servers that store and process data.

Servers are like librarians that fetch the information you request.

🌐 4. The Internet Backbone

Imagine a network of highways that connect major cities. The backbone uses high-capacity fiber optic cables and routers to carry traffic across continents.

Speed is measured in bits per second (bps). For example, a 1 Gbps link can transfer data at:

$1\,000\,000\,000\ \text{bits/s} = 125\,000\,000\ \text{bytes/s}$
