A client is a piece of computer hardware or software that accesses a service made available by a server. The server is often located on another computer system, in which case the client accesses the service by way of a network.
Client Examples
1. Web Browser
A web browser is a prime example of a client. Everyone who uses the internet is familiar with web browsers such as Google Chrome, Safari, Firefox, or Internet Explorer. These browsers request information from servers and then display that information as web pages for users to interact with.

When you type in a URL or click on a bookmark, your browser sends a request to the server where that website’s data is stored. The server then sends back the data, which your browser interprets and displays as a webpage. This happens every time you visit a site, making your web browser an essential client in your daily internet use.
2. Email
Your email application, whether it’s Outlook, Gmail, or any other platform, serves as a client. Typically, these apps are responsible for sending, receiving, and storing emails. They do this by continually interacting with an email server.
When you click “Send” on a new email, your email client sends that message to the email server. The server then sends the email to the recipient’s server, which the recipient’s email client retrieves. In this process, both sending and receiving software act as clients, making email a great example of the client-server model.
3. Online Gaming
Online gaming provides another example of a client. Any online game, from MMORPGs to mobile games, relies on a client-server model for functionality. The game installed on your device is the client, interacting with the central game server to interpret and portray accurate real-time gameplay.
When you perform an action in the game, your game client sends an update to the server. The server then incorporates that action into the game’s overarching state, sending back data about the new game state to your client and those of other players. Through this interaction between client and server, multiple players can participate in the same game session from all around the world.
Conclusion
In the digital world, the client is an essential part of the client-server model, facilitating interactions between users through internet browsers, email, and online games, among other applications. These clients, whether they are web browsers, email applications, or online games, help to establish efficient and effective communication in our increasingly connected world.

Related Questions
1. What is a server in the context of the client-server model?
A server is a central computer or system which hosts data and other services that are accessed and consumed by the client. This can be a web server hosting a website, an email server hosting an email service, or a game server hosting an online game.
2. Can a computer function both as a client and a server?
Yes, a computer can function as both a client and a server. For example, in peer-to-peer networks, each computer can act as both a client requesting resources and a server offering resources.
3. What’s the difference between a web client and a web server?
A web client, like a browser, sends requests to a web server. The server receives these requests, processes them, and sends back the requested information, such as a web page or data, to the client.
4. In email communication, what roles do the client and server play?
The email client is the application, like Gmail or Outlook, used by the person sending or receiving email. The client communicates with the server, which permanently stores the emails and ensures they get to the right destination.
5. How do online games use the client-server model?
Online games use this model to manage real-time interactions between players. The game client on a player’s device communicates with the game server. Player actions are sent from the client to the server, which updates the game state and communicates changes back to all connected clients.
