Client Server Computing Paradigm

 

Client

  • A client is a software application that initiates requests for resources or services from a server.
  • Examples of clients include web browsers, email clients, and mobile apps.

 

Server

  • A server is a computer program or dedicated computer that provides resources or services to clients.
  • Servers can handle multiple client requests simultaneously.
  • Examples of servers include web servers, email servers, and database servers.

 

Communication

  • Clients and servers communicate with each other over a network, often the internet.
  • Clients typically send requests using standardized protocols like HTTP (web) or SMTP (email).
  • Servers process the requests, retrieve or generate data, and send responses back to the clients.

Benefits of Client-Server Computing

  • Centralized Management: Data and applications are stored on the server, simplifying administration and updates.
  • Scalability: Servers can be upgraded to handle more clients or additional clients can be added easily.
  • Security: Access to sensitive data can be controlled on the server side.
  • Resource Sharing: Clients can share resources like printers and databases provided by the server.
