Client facts for kids
In internet talk, a client is like a customer in a shop. It's a computer program or device that asks for information or services from another computer, called a server. Think of your web browser (like Chrome or Firefox) as a client. When you type a website address, your browser (the client) asks a web server for the webpage.

What is a Client?
A client is any computer or software that connects to a network to use services provided by a server. It's the part of a system that you, the user, directly interact with. Clients are designed to make requests and display the information they receive.
How Clients and Servers Work Together
Imagine a restaurant. You (the client) ask a waiter (the network) for food from the kitchen (the server). The kitchen prepares the food and sends it back to you through the waiter. In the digital world, your client program sends a request over the internet. A server receives this request, processes it, and then sends back the information or service you asked for. This back-and-forth communication happens incredibly fast.
Different Kinds of Clients
There are many types of clients, each designed for a specific task.
Web Browsers: Your Internet Window
Your web browser is one of the most common clients. When you visit a website, your browser sends a request to the website's server. The server then sends back the website's files, and your browser displays them on your screen. This lets you see pictures, read text, and watch videos online.
Email Programs: Sending Messages
If you use an email program like Outlook or Thunderbird, that's also a client. It connects to an email server to send and receive your messages. When you send an email, your email client sends it to the server. When you check your inbox, your client asks the server for new messages.
Game Consoles and Apps: Playing Online
When you play online games on a video game console or a mobile app, your device acts as a client. It connects to game servers to let you play with friends, save your progress, or download new content. The client sends your actions (like moving your character) to the server, and the server sends back what other players are doing.
Other Examples of Clients
- Chat apps: Like WhatsApp or Discord, they connect to chat servers.
- File transfer programs: Such as FTP clients, they connect to servers to upload or download files.
- Streaming apps: Like Netflix or Spotify, they connect to media servers to stream videos or music.
Why Clients are Important
Clients are essential because they are the bridge between you and the vast resources of the internet. They make it easy for you to access information, communicate with others, and use online services without needing to understand the complex workings of servers. Without clients, the internet would be much harder to use!
