1、Definition of a Server

A server is a computer or system that provides services to other computers or devices over a network. These services can include storing, managing, and processing data, hosting websites, running applications, and facilitating communication. Servers are designed to handle multiple requests simultaneously, making them more powerful and robust than regular computers.

2、Core Functions of Servers

2、1 Data Storage and Management

One of the primary functions of servers is to store and manage data. Servers are equipped with large storage capacities, allowing them to store vast amounts of data, including documents, images, videos, and databases. This data can be accessed and managed by authorized users, ensuring the availability and security of the information.

2、2 Hosting Websites

Web servers are specialized servers that host websites and make them accessible over the internet. When a user enters a website's URL, the web server retrieves the corresponding web pages and delivers them to the user's browser. This enables organizations and individuals to showcase their content, services, and products to a global audience.

2、3 Running Applications

Application servers host and manage applications, allowing users to access and use them over a network. These servers can run various types of applications, such as email servers, database servers, and collaboration tools.
