What is a server? So that is a topic of this  video. Now a server is basically a dedicated  

computer that provides services on behalf of  clients, such as ordinary desktop computers  

or workstations. So it's a centralized machine  where multiple clients connect to, either over  

the Internet or in a local area network, and they  connect to a server for a specific service. So  

for example, that service could be to retrieve a  website, to access data, or email, and so on. Now  

a server could be dedicated to handle one of these  services only, where you would have one server  

it dedicated for a website, one server for data  storage, and a server for email. And this model is  

what larger organizations use. Or you can also set  up a server to handle each of these services on  

the same machine which is what typically happens  in smaller organizations. So depending upon which  

setup is used it all depends on the needs of an  organization. Now when people talk about a server  

generally they are referring to a powerful  centralized computer that clients connect to  

over a network, and they would be correct on that.  However a server is not just a physical computer.  

A server is actually a role that a computer takes.  Because any ordinary desktop computer can be set  

up as a server and it doesn't necessarily have to  be a powerful computer. So for example you can set  

up a network in your home where you can have an  ordinary desktop computer serve as a file server.  

The computer would have those files in a shared  folder and then other computers can't connect to  

it to access those files. Or you can also use  a desktop computer to serve as a web server,  

where you would install the website data on that  computer and then the other computers can connect  

to it and retrieve the webpage. However desktop  computers do have their limitations because they  

are not designed to handle a large workload and  they can't handle a lot of incoming connections  

from users. And this is not only because of their  inferior hardware, but it's also because of software.
