Defining a Server
A server provides services to other computers on a network. A server can be an expensive Windows 2008 Server, or a simple Windows XP Home computer with a shared printer.
Operating System
Server Operating Systems are more stable and secure then Desktop operating Systems
Server Operating Systems and their Software are generally much more expensive then Desktop counterparts
Server Operating Systems are generally not as easy to administer as Desktop Operating Systems
Hardware
A Server can use ANY hardware to operate, but Server Hardware is made to be more reliable then desktop hardware.
Xeon Processors are standard processors used in servers
Redundant Power Supply allow one power Supply to Fail while the Server is Still Running
RAID -- Allows for a Hard Drive to fail without crashing the Server
ECC RAM is RAM that does a self test. It is more stable then regular RAM, but much more expensive.
Types of Servers
Software features -- multiple features can be on one box
Security and Authentication gives access to network resources
Print Servers share printers on a network
File Servers share files on a network
Web/ FTP Servers provide websites on a network
Mail Servers provide email routing for an organization
Database Servers store data for outside applications
Remote Access Servers allow Internet users to access the internal network. Usually a VPN connection.
Final Thoughts...
Buy what you need... Many people buy a $5000 server when all they need is a Dell bargain bin system.
