Internet Server
Definition of Internet Server:
In computing, a server is a computer program or a device that provides functionality for other programs or devices, called “clients”. This architecture is called the client-server model, and a single overall computation is distributed across multiple processes or devices.
Or,
A Web server is a program that uses HTTP (Hypertext Transfer Protocol) to serve the files that form Web pages to users, in response to their requests, which are forwarded by their computers’ HTTP clients. Dedicated computers and appliances may be referred to as Web servers as well.
Or,
A server is a computer program that provides services to other computer programs (and their users) in the same or other computers. The computer that a server program runs in is also frequently referred to as a server. That machine may be a dedicated server or used for other purposes as well
Function of Internet Server:
- The client’s browser divides the URL into diff. parts dividing including address, path name and protocol.
The server is usually a high end PC - Servers provide network resources
- Server is not designed to be used
- DNS translates the domain name into the corresponding IP address the numeric combination represents the site’s true address on the internet.
- The server sends a GET request to the web server to retrieve the address it has been given. It verifies given address exists, finds necessary files, runs appropriate scripts exchanges cookies if necessary and returns back to the browser,
- The browser now converts the data into HTML and displays results to the user. If it does not locate it sends an error message to the browser and to the client.
Types of Server:
The table below lists the most common types of servers that are implemented on a network:

| 3. Communications server | Handles many common communications functions for the network, such as e-mail, fax, remote access, firewalls or Internet services |
| 4. Application server | Shares network-enabled versions of common application software and eliminates the need for software to be installed on each workstation |
| 5. Database server | Manages common databases for the network, handling all data storage, database management and requests for data |
