A Network Client is a software application or device that requests services or resources from a server in a computer network. It operates by sending requests over the network, which the server processes and responds to. Common examples of network clients include web browsers, email clients, and file transfer applications. Network clients rely on protocols, such as HTTP for web browsing or SMTP for email, to communicate effectively with servers. They can be found on various devices, including personal computers, smartphones, and tablets, allowing users to access and utilize networked resources seamlessly.
