In computer networking, a client refers to a device or computer application that requests a service or resources from a server.
Clients can take many forms, such as web browsers, email clients, file transfer clients, and other applications that require access to resources or data provided by a server. Clients typically connect to servers over a network, such as the internet, and communicate with them using protocols such as HTTP, FTP, and SMTP.
When a client requests a service or resource from a server, the server responds with the requested data or service. For example, a web browser is a client application that requests web pages from a web server, and the server responds with the requested web pages.
Clients can run on various devices, including desktop computers, laptops, tablets, smartphones, and other mobile devices. They can be stand-alone applications or web-based applications that run within a web browser.
In summary, a client is a device or application that accesses resources or services provided by a server over a network.
