Client-Server Model§
Definition§
The client-server model is a network architecture where tasks or services are distributed between service providers (servers) and service requesters (clients). In this configuration, the server is a central computer that provides resources, data, or services to multiple client computers, which communicate via a network.
Examples§
- Web Browsing: Web browsers (clients) request web pages from web servers using HTTP/HTTPS protocols.
- Email Services: Email clients (like Microsoft Outlook or Gmail) communicate with email servers to send, receive, and store emails.
- Database Access: Applications use SQL clients to request data or services from a database server.
- File Sharing: File servers store data that can be requested and accessed by multi-user client computers.
- Gaming: Online multiplayer games often use game servers to manage and synchronize the actions of multiple gaming clients.
Frequently Asked Questions (FAQs)§
Q1: What roles do clients and servers play in a client-server model?
A1: Clients request services or resources, while servers fulfill those requests by providing the necessary data and resources.
Q2: Can a computer function both as a client and a server?
A2: Yes, a computer can act as both a client and a server depending on the tasks and roles it is assigned in the network.
Q3: What are the advantages of the client-server model?
A3: It offers centralized resource management, better security and data management, and easier maintenance of client functions.
Q4: What are some common protocols used in the client-server model?
A4: Common protocols include HTTP/HTTPS (web services), SMTP/IMAP/POP3 (email services), and SQL (database access).
Q5: What are the potential disadvantages of the client-server model?
A5: It can be costly to set up, is vulnerable to server failures, and may have performance bottlenecks if the server is overloaded.

- Thin Client: A lightweight computer that relies heavily on the server for processing power and data storage.
- Thick Client: A client that performs the bulk of processing tasks and has its own storage but relies on the server for certain services and data.
