Learning objectives, network hardware fundamentals, types of network hardware.

00:12.000 --> 00:18.000
We're going to learn about network hardware, the devices that help computers talk to each other.

00:18.000 --> 00:23.000
Imagine the internet as a giant web connecting billions of devices, but how do they communicate?

00:23.000 --> 00:27.000
That's where network hardware comes in, routers.

00:27.000 --> 00:31.000
A router is a networking device that connects multiple devices to the internet.

00:31.000 --> 00:41.000
Example, a home Wi-Fi router connects smartphones, laptops, and smart devices to the internet.

00:41.000 --> 00:43.000
Switches

00:43.000 --> 00:54.000
A switch is a networking device that connects multiple devices within the internet and transfer data only to the connected user.

00:54.000 --> 01:04.000
Example, in your computer lab, a switch connects computers, printers, and servers, enabling fast communication between them.

01:04.000 --> 01:16.000
Hubs, a hub, is a simple device that connects many computers in a network and sends the same message to all of them, even if only one needs it.

01:16.000 --> 01:22.000
Example, in a school, if a teacher sends a message to one student, but all students hear it,

01:22.000 --> 01:29.000
that's like how a hub works. It shares everything with everyone.

01:29.000 --> 01:36.000
Access points, Wi-Fi devices. Wireless access points allow devices to connect without cables.

01:36.000 --> 01:41.000
Example, your phone connects to Wi-Fi at school using an access point.

01:41.000 --> 01:49.000
Cables, Ethernet cables are physical wires used to connect devices within a network, ensuring fast and stable internet connections.

01:49.000 --> 01:56.000
They are commonly used to link computers, routers, switches, and other networking hardware.

01:56.000 --> 02:07.000
We learned about routers, switches, hubs, and Wi-Fi access points. These devices work together to keep us connected.
