Servers Explained Like a Hospital 🏥 (For Newbie Tech Readers) - Part 1

If you’re new to tech, you’ve probably heard the word “server” a lot. But what is a server really? Is it hardware? Is it software? Or both? 🤔

Don’t worry—let’s break it down in a way anyone can understand. Imagine a hospital.

🏗️ Hardware = The Hospital Building

Think of hardware as the actual hospital building. It’s the walls, rooms, beds, equipment, and power supply. Without the building, doctors and nurses have nowhere to work.

In the same way, a physical server is the computer hardware—CPU, RAM, hard drives, and network cards.

👩‍⚕️ Software = The Doctors and Nurses

Now imagine the hospital staff: doctors, nurses, and specialists. They don’t own the building, but they run it, organize patients, and deliver the services.

This is what server software does. Examples:

  • Web server software (like Apache, Nginx) – serves websites.

  • Database server software (like MySQL, PostgreSQL) – manages information.

  • File server software – stores and shares files.

Without staff, a hospital building is just an empty shell. Without software, a server computer is just an expensive box.

⚡ The Combination = A Running Hospital

When you combine hardware (building) + software (staff), you get a working hospital that can serve patients.

Same with servers:

  • Hardware = the machine.

  • Software = the program running on it.
    Together, they serve users (you, me, everyone on the internet).

🌍 Real-Life Examples of Servers

  • Facebook / TikTok / YouTube → Their servers deliver the content you see every day.

  • Banks → Their servers handle online transactions securely.

  • Hospitals (real ones!) → Medical servers store patient records and images.

In short: If you’re online, you’re already using servers—even without noticing.

🏡 Bonus: Your Home Router is Also a Server!

Servers aren’t just in big data centers—they also exist in your home.

👉 You also have a server at home—your Wi-Fi router.

When you connect your phone, laptop, or smart TV, your router automatically hands out IP addresses to your devices. This process is called DHCP (Dynamic Host Configuration Protocol).

And that makes your router a DHCP Server.

It’s just like the hospital’s admissions counter:

  • New patient = new device.

  • Room number = IP address.

  • The counter assigns the room so patients know where to go.

I already explained this in a previous blog post:
👉 DHCP for Dummies: How Your Devices Get Their IP

So yes—even at home, you’re already using a server without realizing it!

📝 Quick Analogy

  • Server Hardware = The building (CPU, RAM, storage).

  • Server Software = The staff (programs providing services).

  • Server (Full) = Hardware + Software working together.

  • Example at Home = Your router as a DHCP server.

🚀 Final Words

Servers aren’t mysterious or complicated—they’re just computers designed to serve information and services.

By thinking of servers as hospitals—with hardware as the building and software as the staff—you can easily understand what they are and why they matter.

👉 Whether it’s your favorite apps or even your home Wi-Fi router, servers are working behind the scenes to keep everything connected.

  Configuration Disclaimer:  this one again is only for  ubuntu 18.04  and login as  root  user to be sure Make sure you have a good understanding of the suricata rules before doing this This might cause some disconnection from the site or services you are visiting and even the internet if not properly configured. In the real environment it is best not to run as root user but for the sake of just testing it I opted to run as root configure the following rules on your mikrotik router: /ip firewall filter add action=drop chain=input comment="Block bad actors" src-address-list=Blocked /ip firewall filter add action=drop chain=forward comment="Drop any traffic going to bad actors" dst-address-list=Blocked create a user group with all policies checked except telnet create a user allowing your local addresses with the group you created earlier Lets Start ... 1.      Install PHP         apt install php -y 2.   Navigate...

Why upload comes first before download

Before we dive into why upload comes first, let’s quickly define upload and download in data communication. Upload refers to sending data from your device to a remote server or another device. This happens when you send an email, upload a file to the cloud, or even just request a webpage. Download is the process of receiving data from a remote source to your device. This includes streaming videos, loading webpages, or saving files from the internet. Think of it like a conversation: when you ask someone a question (upload), they respond with an answer (download). The same applies to internet communication—before you can receive data, you must first send a request. Why Upload Comes First in Data Communication Now that we understand uploads and downloads, let’s put it in simple human terms. Imagine you’re having a conversation with a friend: You ask a question (Upload): Before your friend can give you an answer, you first need to say something—whether it’s a question, a request, or a ...
