software specific to the purpose of the server. For example, a Web server may run Apache HTTP Server or Microsoft IIS; these programs provide access to websites over the Internet.
A mail server might run Exim or iMail; these programs provide SMTP services for sending and receiving emails. A file server might use Samba or another file-sharing program to share files over a network.
