What do servers do?
|
|
|
| i recently visited a business that had servers up the yang. I am
wondering why do they need all of those... Like what is the importance
of having so many servers? Are they used for storage and if so then
why dont they put files on other less (in my opinion) expensive
servers...
anything would be good. thanks

| Asking what servers do is kind of like asking what books do.
Servers provide a whole mass of different capabilities. Here's a couple of
examples:
Some servers are designed to grant or deny permission to access various
networked resources
Some servers provide databases where you can obtain information such as your
account information from your bank
Some servers provide Email access and newsgroups like this one.
Just a few examples to give you an idea. Basically, servers store
centralized access to applications.

| So then how would you go about setting up a redhat or a windows server
to supply these services, do you have to program or buy software??
also is it possible to "serve" an application like Word so you dont
have to install it on a bunch of different machines?

| This has got to be a joke.
He must have some idea how a computer works, he posting on a newsgroup.
Just in case your serious, first I would suggest that you do a little
research on your own. Otherwise you're going to get answers that do nothing
but confuse you. Second you will have to post more specific questions to the
appropriate group. I'll give you little information here even though I still
half think this is a joke.
"Server"
This is a general term applied to both hardware and software that provides
some kind of service or resource to other hardware, software, and/or users.
"Server hardware" is basically a computer of some sort with all the
necessary components to run the server Operating System (OS). Usually these
are built to be more robust then a desktop PC with additional protection
from component failure. Although, as you will discover, most server OS will
run on low end hardware, just slower and less reliably.
"Server OS" Hopefully you know what an Operating System is. Some are
designed for desktops, such as Win XP, others for servers. In general a
server OS can better deal with errors, and is designed to perform file
transfers, and run background applications more efficiently then a desktop.
An example would be that while a desktop might benefit from a high-end
graphics card and be able to process the images quickly, a server OS would
not need this and usually wouldn't even have a monitor attached.
"Network Services" are provided to the network by "Servers". These services
might be included in the OS or may be additional software that must be
installed on the Server. Services include;
File storage and access
Print queues (shared printers)
DHCP
DNS
WINS (no wise-cracks)
Web servers
News server
Time server
E-Mail servers
Database servers
TAPI
and on and on
As for how to set these up, well you will have to work on this yourself. And
as far as Word goes, this is an application not a network service and is
designed to be installed on the workstation. There is a Word network
installation but in reality it is run on the local PC with the files stored
on a "File Server".
It's surprising how much you can type while you waiting for large print job
to complete ;-)

Actually, there are things such as application servers that will allow
access to applications without them being installed on the workstations.
All the programs reside on the servers, and all the processing is done
there. The clients just get screen shots. Check out Microsoft Terminal
Services and Citrix. Very nice for some basic applications, such as Word,
but fall flat on graphics intensive programs.
