What is a Server?

A server is nothing more than your desktop PC but a little more reliable, scalable and provides more redundancy. It "serves" clients or users requesting information from it. There are several ways a server can be used. Use it as a central unit to store multiple files in the network, ISPs use it as a DNS or a DHCP to convert domain names or assign IP addresses to users. There can be a 100 uses of a server. You just need to choose the right one for you or your business.

How can a server help me?

It all depends on what you're trying to do with it. If you are setting up a business where there are multiple computers connecting to a network, you can connect all the systems to the server such that they act as clients and store all the information in the server. Servers are manufactured such that they would be able to run 24 hrs a day, 7 days a week and 365 days a year meaning minimum downtime. So if you think you need a server at home, then think again.

What do I need to set up a server?

Setting up a server is pretty much easy. All you need to do is install a server operating system and you have all the options included right in them. Here are a few that rock the charts:

  • Windows Server 2012
  • Redhat (RHEL 7.0)
  • Oracle Solaris 11.2
  • VMWARE ESX Server 5.5
These are just a few of them. There are several other operating systems out there that provide robust features depending on your needs. 

What can a server do?

A server can perform multiple tasks at the same time (termed multitasking) such as print your documents, allow you to play games on LAN, block entry of unwanted threats into the network, help you send and receive emails in your network or outside if connected to Internet and the list goes on and on. So before you decide to get a server, find out what you are planning to do with it. 

Types of Servers:

Depending on their capabilities and performance, servers are divided into several types. Here's a small list with a brief intro:

  • Rack Servers: Usually mounted on racks present in datacenters, these servers are mounted in a bunch along with other servers.

  • Blade Servers: Blade servers are really in the trend today. These guys are also setup in a big unit called the blade enclosure that provides them with basic needs such as the power supply and temperature management. Not just that, they have higher potential and the hardware also is more easily accessible. 

  • Tower Servers: These servers are independent that are placed in cases just like our old desktop PCs. They come with high configurations and make it easier if you need to extend the hardware features.

The above types are just a few to mention. There are several more that are out there but these three are widely used in most of the datacenters. So this was just an introduction of what servers are and what they can do. Let's catch up again later for some more news on them.
