A computer server is a powerful computer or system of computers that is dedicated to managing and serving network resources and services to other devices, known as clients, within a computer network. It is designed to handle various tasks and provide specific functionalities to support the smooth operation of networked systems.
Servers can serve different purposes depending on their configuration and the services they provide. Some common types of servers include:

Servers are typically more robust and have greater processing power, memory, and storage capacity compared to regular desktop or laptop computers. They often run specialized server operating systems and software designed for managing and delivering network services efficiently and securely.
In organizations and businesses, servers play a crucial role in supporting network infrastructure, data storage, collaboration, communication, and application delivery. They enable the efficient sharing and processing of information across the network and ensure reliable and secure access to resources for clients.
