What is client/server network and types of servers?

Local Area Networks are of two types − Peer to Peer network and client/server network.

A client/server network is a network architecture where certain computers act as servers that provide resources and services, while other computers act as clients that request and use these services. This centralized approach forms the foundation of most modern business networks.

How Client/Server Networks Work

In this architecture, a server is a dedicated computer that provides network resources and services to other computers when requested. A client is a computer running programs that request services from servers. All network resources such as files, directories, applications, and shared devices are centrally managed and hosted on servers, then accessed by clients as needed.

Advantages

• Enhanced security − Centralized security management and access control

• Better performance − Dedicated server resources optimize network performance

• Centralized backup − All critical data stored on servers can be backed up systematically

• High reliability − Server redundancy and professional maintenance ensure network availability

Disadvantages

• Professional administration required − Needs skilled network administrators

• Hardware intensive − Requires powerful server hardware and infrastructure

• Higher costs − Expensive server software licenses and maintenance

Types of Servers

File Server − Provides centralized file storage, retrieval, and management services. Users can read, write, exchange, and manage files through the network.

Print Server − Controls and manages network printing resources, handling print queues and providing fax services to network users.

Application Server − Hosts and runs applications that can be accessed by multiple network clients, sharing expensive software and computing resources.

Database Server − A specialized application server that manages database operations, storing and retrieving data for client applications.

Web Server − Serves web pages and handles HTTP requests from web browsers, hosting websites and web applications.

Mail Server − Manages email services, handling the sending, receiving, and storage of electronic messages across the network.

Conclusion

Client/server networks provide a centralized, secure, and efficient approach to network resource management. While they require professional administration and higher costs, they offer superior performance, security, and reliability for business environments.
