Client
In computing, a client is a piece of hardware or software that accesses a service made available by a server as part of a client-server model. It initiates requests to servers and processes the responses, typically in networked environments like the web, databases, or distributed systems. Clients can range from web browsers and mobile apps to desktop applications and IoT devices.
Developers should understand client concepts when building applications that involve network communication, such as web development, mobile apps, or microservices architectures. It's essential for designing user interfaces, handling API calls, managing state, and ensuring efficient data exchange between front-end and back-end systems, particularly in modern full-stack or cloud-native development.
