How it works: Internet and ethernet connections!

Ethernet Cable

How it worksEthernet

  • Wired connection – You plug a cable (usually called an Ethernet cable) from your computer or device into your router or modem.

  • More stable and faster – Since it’s a direct physical connection, you get less interference, lower latency, and a more consistent speed.

  • Used for: desktops, gaming consoles, smart TVs, and situations where speed and stability are important.

Wi-Fi

  • Wireless connection – Your device connects to the internet through radio waves sent by your router.

  • More convenient – No cables, so you can move around freely.

  • Can be less reliable – Walls, distance, and other signals can interfere with it.

  • Used for: phones, tablets, laptops, smart home devices, etc.


How Ethernet Works

  1. The Ethernet cable connects your device to a network switch, router, or modem.

  2. That cable carries data using electrical signals.

  3. It's governed by a set of standards called IEEE 802.3, which define how data is sent and received.


What is Gigabit Ethernet?

  • Speed: It can transfer data at up to 1,000 megabits per second (1 Gbps).

  • "Gigabit" just means one billion bits per second.

  • Use case: Ideal for high-speed internet plans, file transfers, gaming, streaming, and connecting to network storage.

  • You need:

    • A device with a Gigabit Ethernet port

    • A Gigabit-capable router or switch

    • At least a Cat 5e or Cat 6 Ethernet cable


Why Use Gigabit Ethernet Over Wi-Fi?

  • Speed and reliability: Especially if you’re streaming 4K, gaming online, or transferring big files.

  • Lower latency: Better for real-time stuff like Zoom, Teams, or online games.

  • Consistent performance: No signal drop or lag like Wi-Fi sometimes has.
