A computer or other device that stores and transmits web pages, applications, and other types of data via the internet is called a server. It is a crucial part of every website since it offers the underpinning infrastructure needed for users to access the website's content. Important data on user data, security precautions, backups, and other topics are also stored on servers. A website must be hosted on a server that can serve web pages swiftly and securely for it to function correctly.
