What is a server
In the world of I.T., a server is a computer that provides access or data to other computers. It can deliver data to devices on a local area network (LAN) or a wide area network (WAN) through the internet.
There are many types of different servers that currently exist which include web servers, file servers, domain controllers, media servers and mail servers. Each server runs software which is specific to the purpose of the server. A web server may run Microsoft IIS or Apache HTTP Server, which both allow access to websites through the internet. A mail server will run iMail, Exchange or Exim which allows SMTP services for sending and receiving email. A file server can utilize integrated software or third party software such as Samba to share resources over a network.
