Client
Definition
A client is a device or software that requests and uses services provided by a server in a network.
What Problem It Solves
It allows users or devices to access shared resources (like websites, files, emails, or applications) without needing to store or manage everything locally.
What Happens If Not Used
Without clients, users would not be able to request or interact with services from servers. Every system would need to operate independently, making networks useless for sharing resources.
Easy Wording
A client is something (like a computer or app) that asks a server for information or services.
Layman Example
When you open YouTube on your phone and watch a video, your phone is the client asking YouTube’s servers to send the video.
Technical Example
A web browser (like Chrome) acting as a client sends an HTTP request to a web server. The server processes the request and responds with HTML, CSS, and JavaScript, which the browser renders as a webpage.
