This document summarizes several common server types: DNS, DHCP, FTP, Apache, Samba, NFS, and email servers. It provides brief descriptions of the purpose and functionality of each type of server, such as that DNS servers translate domain names to IP addresses, DHCP servers automatically assign IP addresses on a network, and email servers transfer emails between computers using protocols like SMTP, POP3, and IMAP.

4.  DNS Server
 DHCP Server
 FTP Server
APACHE Server
 SAMBA Server
 NFS Server
 EMAIL Server

5. Serves as the "phone book" for the
Internet
Translates human-readable computer
hostnames into IP addresses
Also stores other information

7. Automatically assigns IP addresses to
devices (I.e. hosts) on your network
Prevents having to manually enter data
Steps used in Configuration-
 DHCPDISCOVER
 DHCPOFFER
 DHCPREQUEST
 DHCPACK

9. Red Hat's standard web server
More then 60% sites are hosted on apache web
server
Apache support virtual hosts in which multiple
web sites may share the same web server

10.  Developed by Andrew Tridgell
 Allows file and print sharing between
computers running Windows and computers
running Unix
 It was originally developed for Unix and
Unix-like systems, like Linux, Solaris, Mac OS
X, etc

12.  It stands for Network File System
 It was originally developed by Sun
Microsystems
 It allows user on a client computer to
access files over a network in a manner
similar to how local storage is accessed

14. FTP is a standard mechanism for copying a
file from one host to another
FTP uses the services of TCP
It needs two TCP connections-
port 21 is used for the control connection
port 20 for the data connection.

16.  It is a computer that serves as an electronic post office for
email
 It’s a computer that performs MTA (Mail Transfer Agent)
function, i.e., it transfers mails from one computer to another
 Protocols used for
 Sending Mails- SMTP (Simple Mail Transfer
Protocol), sendmail
 Receiving Mails- POP3 (Post Office Protocol), IMAP
(Internet Message Access Protocol)
