What is a Server?

A server is a computer system or software application that provides services, data, or programs to other computers, known as clients, over a network. Servers are powerful machines designed to manage, store, send, and process data 24/7.

Core Functions of a Server

Servers perform critical networking functions such as:

• File Hosting: Storing and sharing files between users and systems.
• Database Services: Managing and retrieving structured data using database software like MySQL or MongoDB.
• Web Hosting: Delivering website content through HTTP/HTTPS protocols.
• Application Services: Running applications that clients can access remotely (e.g., mail servers, game servers).

Types of Servers

There are various kinds of servers tailored to specific tasks:

• File Server: Shares files across a network.
• Web Server: Hosts websites (e.g., Apache, Nginx).
• Database Server: Manages databases (e.g., Oracle, PostgreSQL).
• Email Server: Manages and transfers emails.
• Application Server: Hosts and runs specific applications or services.

Client-Server Model

Servers operate on the client-server model, where clients request resources or services, and servers respond. This model provides centralized control, easier maintenance, and secure data sharing, making it a foundational architecture in modern networking.

Importance of Servers in Networks

Servers are the backbone of modern networks. They manage user requests, ensure data integrity, provide resource availability, and play a pivotal role in cloud computing and enterprise IT infrastructures.
