Server

A server is a powerful computer designed to provide data, resources, and services to other computers, known as clients, over a network. Servers can host various types of services, including web pages, email, file transfer, and name resolution. In a client-server architecture, the server is a central computer that manages resources, shares file storage, and handles communication across a network.

Examples

  1. Web Server: Sends web pages to clients’ browsers on request. Examples of web servers include Apache HTTP Server and Microsoft Internet Information Services (IIS).
  2. Mail Server: Manages and delivers email messages. Examples include Microsoft Exchange Server and Postfix.
  3. FTP Server: Stores files and facilitates file transfers. Common examples are FileZilla Server and vsftpd.
  4. List Server: Administers mailing lists, allowing for automated email distribution to subscribers. Examples include Mailman and Majordomo.
  5. Name Server: Provides information about Internet host names and addresses. Domain Name System (DNS) servers are a typical example.

Frequently Asked Questions

  1. What is the primary function of a server?

    • A server’s primary function is to provide resources, data, services, or programs to other computers, known as clients, over a network.

  2. Can a single server perform multiple tasks?

    • Yes, a single server can be configured to perform multiple tasks, such as being a web server, mail server, and FTP server simultaneously.

  3. What is a local area network (LAN)?

    • A LAN is a network that connects computers within a limited area such as a residence, school, or office building.

  4. How does a web server work?

    • A web server listens for incoming requests from clients (web browsers), retrieves the requested pages or resources from web storage, and sends them to the clients’ browsers.

  5. What are the benefits of using a centralized server in a network?

    • Centralized servers can simplify resource management, ensure data integrity, enhance security, and provide centralized backup and recovery solutions.
  • Client-Server Model: A network architecture where clients request resources and services from a centralized server.
  • DNS (Domain Name System): A hierarchical naming system for computers, services, or any resource connected to the Internet or a private network. It translates domain names into IP addresses.
  • HTTP (HyperText Transfer Protocol): An application protocol for distributed, collaborative, hypermedia information systems, primarily used for web communications.
  • SMTP (Simple Mail Transfer Protocol): An Internet standard for email transmission across IP networks.
