Client-Server Architecture is a computing model that divides tasks between service providers, known as servers, and service requesters, known as clients. In this setup, clients send requests to servers, which process the requests and return the appropriate responses. This structure allows for efficient resource management and enables multiple clients to access shared resources simultaneously. The architecture is commonly used in various applications, including web services and database management. Servers can host applications, store data, and perform complex computations, while clients can be personal computers, mobile devices, or any other system that interacts with the server. This separation enhances scalability and performance.
