What Is a Server?
A server is a hardware or software system that provides services, resources, and functionality to client devices or programs. This relationship is defined by a client-server model.
Servers exist in 2 primary forms: hardware servers and software servers. A hardware server is a physical machine specifically designed to run server software. These machines are built for continuous operation, often featuring redundant components like power supplies and cooling systems to minimize downtime. A software server refers to the programs or applications that provide services to clients. For example, a web server like Apache or Nginx is software that runs on a hardware server to deliver website content.
How Does a Server Work?
Servers operate using a request-response model. In this model, a server listens for incoming requests from clients over a network. When a request is received, the server processes it and responds to fulfill the request with the appropriate data or service.
To handle these tasks efficiently, servers rely on specialized operating systems (OS). These operating systems help the server manage resources, handle multiple simultaneous requests, and ensure security. Servers also rely on runtime environments, which are a software layer that provides an execution context for server applications to run smoothly.
