Server software is a type of program designed to manage and deliver services to other computers, known as clients, over a network. It runs on a server, which is a powerful computer that stores data and applications, allowing multiple users to access resources simultaneously. Common examples of server software include web servers, database servers, and file servers. These software applications handle requests from clients, process them, and send back the appropriate responses. For instance, a web server delivers web pages to users' browsers, while a database server manages data storage and retrieval for applications. Overall, server software is essential for enabling communication and resource sharing in a networked environment.
