Start Networking

Thanks to your intervention, the monitoring system is back online.
The team lead thanks you for resolving the incident.

Now, you need to know a few basics.
We will continue practicing together and move step by step.

End Devices vs Network Devices

To continue practicing, you first need to understand what types of devices exist in a network.
In a network, equipment can be grouped into two categories.

Figure 1 - End Devices and Network Devices

• End devices
  Computers, laptops, phones, or printers.
  These are the devices used directly by people and applications.

• Network devices
  Switches, routers, and firewalls.
  These devices make communication possible between end devices.

As a network administrator, you will mostly work with network devices, starting with switches.

For now, there is nothing to configure.
This step is here to make sure these basics are clear before moving on.

When you are ready, mark this step as complete and continue.

Imagine it is your first day as a network administrator.
You sit at your desk and connect your computer to the company network by plugging it into a switch.

Figure 2 – A computer connected to a switch in a local network.

Why the Switch Matters

A switch allows multiple devices to connect and communicate with each other.
In an office, you are usually connected to the same switch as other employees.

Figure 3 – The switch connects end devices in the network.

In the next step, you will access the switch and interact with it directly.
Your first goal will be to name the switch.

Open the CLI

You do not need to understand everything yet.
Just follow the instructions and observe what happens.

Nothing can break.
This is a safe environment designed for learning.

When you are ready, click Start CLI to begin, then follow the instructions.

Once the Instructions Are Complete

You can see that the hostname has changed.
Great job!

These are simple actions, but they are exactly how network administrators start.

Understanding will come step by step.
For now, what matters is that you were able to do it.
