Data server

(also database server, DS)

Data server definition

A data server is a computer or platform used for storing, securing, managing, and processing data. Data servers can have various purposes — from hosting websites and storing files to running applications and handling data requests from devices. Sometimes, computer hardware can also be considered a database server.

How does a data server work?

  1. 1.The server stores data (like files or websites) on its hard drives.
  2. 2.When another computer on the network wants to access that data, it sends a request to the data server.
  3. 3.The server processes the request and finds the requested data.
  4. 4.It sends the data back to the computer over the internet or network.
  5. 5.The server has several security measures in place to keep data safe from unauthorized access.

Those responsible for the servers (e.g., system admins) typically check them regularly to make sure they’re working well.

Real-world applications of data servers

  • E-commerce companies (e.g., Amazon) use data servers to manage product catalogs, customer accounts, and transaction data.
  • Social media sites like Facebook, Twitter, and Instagram rely on data servers to store millions of user profiles, posts, images, and videos.
  • Email providers (e.g., Gmail, Outlook, and Yahoo Mail) use data servers for delivering email messages to users.
  • Banks use servers to securely manage customer account information and transaction history.
  • Healthcare systems use data servers for storing and managing patient medical records, test results, and treatment histories.
